CDi DriveCore Series Operation Manual

Hardware Setup

Connecting the AC Power Cord

IMPORTANT: The ampliﬁer output mode must be properly conﬁgured for the application before connecting the speakers and powering on the ampliﬁer.

By default, all outputs are conﬁgured for Low Z operation. See "Conguring the Amp" on page 11 for more information.

Connect your ampliﬁer to the AC mains power outlet using the supplied AC power cord. First, connect the IEC end of the cord to the IEC connector on the

ampliﬁer. Then plug the other end of the cord to the AC mains.

WARNING: The third prong of the power connector (ground) is an important safety feature. Do not attempt to disable this ground connection

by using an adapter or other methods.

Make certain the AC mains voltage and current ratings are sufﬁcient to deliver full power to all ampliﬁers. CDi DriveCore Series ampliﬁers use a universal

power supply. The AC voltage requirements are 100V-240V~, 50/60Hz (±10%). If the AC line voltage varies outside of this acceptable range, the ampliﬁer’s

power supply will turn off and the blue Power LED will ﬂash. The ampliﬁer will turn back on when the AC line voltage returns to safe operating levels.

Power Up Procedure

When turning on the ampliﬁer for the ﬁrst time:

1� Ensure all connections are disconnected with the exception of the power cord.

2� POWERPress the ampliﬁer's button. The Power indicator will light blue and the ampliﬁer will boot as long as sufﬁcient mains power is provided.

3� ENCODEROnce boot up is complete, turn the counter-clockwise until all amp levels are set to -80dB in the front panel LCD.

4� Conﬁgure the ampliﬁer as described in "Conguring the Amp" on page 11.

NOTE: The ampliﬁer output mode must be properly conﬁgured for the application before connecting the speakers and powering on the ampliﬁer. By

default, all outputs are conﬁgured for Low Z operation.

5� Once the ampliﬁer has been properly conﬁgured for the application, turn off the power — by pressing and holding the Power button for 2 seconds —

then disconnect the power cord.

6� Turn down the level of your audio source.

7� Make all connections as described in "Wiring Input Connectors" "Wiring Output Connectors" on page 7. and

8� Once all connections have been made, reconnect the power cord and turn on the ampliﬁer power.

9� Turn your audio source up to an optimum level. Refer to all device meters and ensure that at no point in the signal chain is the signal being clipped in

any way. If any of the ampliﬁer's Clip indicators light yellow, reduce the source level until the Clip LEDs no longer light.

10� Turn the ampliﬁer's clockwise until the desired loudness or power level is achieved, while making sure the ampliﬁer's clip LEDs do not ENCODER

light.

IMPORTANT: Always turn off the ampliﬁer — by pressing and holding the Power button for 2 seconds — and disconnect the power cord before making

any wiring or installation changes.

IMPORTANT: When powering a fully conﬁgured PA system, always turn the ampliﬁers on last and off ﬁrst.

For help with determining your system’s optimum gain structure (signal levels) please refer to the Crown Ampliﬁer Application Guide, available online at

www.crownaudio.com.

Page 6 CDi DriveCore Series Operation Manual

Hardware Setup

Precautions

Your ampliﬁer is protected from internal and external faults, but you should still take the following precautions for optimum performance and safety:

1� Conﬁgure the ampliﬁer for proper operation, including input and output wiring hookup. Improper wiring can result in serious operating difﬁculties.

For information on wiring and conﬁguration, please consult "Wiring Input Connectors" "Wiring Output Connectors" on page 7 and .

For advanced setup techniques, consult Crown’s Ampliﬁer Application Guide available online at www.crownaudio.com.

2� Use care when making connections, selecting signal sources, and controlling the output level. The load you save may be your own!

3� Do not short the ground lead of an output cable to the input signal ground. This may form a ground loop and cause oscillations.

4� Never connect the output to a power supply, battery, or power main� Electrical shock may result�

5� Tampering with the circuitry or making unauthorized circuit changes may be hazardous and invalidate all agency listings.

6� Do not operate the ampliﬁer with the Clip LEDs constantly ﬂashing.

7� Do not overdrive the mixer, which will cause clipped signal to be sent to the ampliﬁer. Such signals will be reproduced with extreme accuracy, and

loudspeaker damage may result.

8� Do not operate the ampliﬁer with less than the rated load impedance. Due to the ampliﬁer’s output protection, such a conﬁguration may result in

premature clipping and speaker damage.

REMEMBER: Crown is not liable for damage that results from overdriving other system components.

• The HiQnet address is not displayed, instead a dash is displayed as grayed out.

NOTE: A conﬂicting HiQnet address may be edited inline if you want to change the device HiQnet address.

NOTE: Devices are not discoverable at the IP level. A device which is not discoverable at the IP level (invalid IP address, etc.) will not be able to

report a HiQnet address. In this instance, the HiQnet ID ﬁeld will display a "?" to indicate that the ﬁeld may exist but that the software does not have

enough discoverability of the device to determine the value. A blank ﬁeld or "-" implies the value is null and the HiQnet ID ﬁeld may not be edited

inline.

NOTE: Apply Current Edits Apply and ExitOnce edits have been made, it is critical to click the or buttons for the changes to take affect.

7� Random ID Reboot

When enabled, the device will be given a random HiQnet address. If you want to set the HiQnet address of a device to a random ID, check the Random

ID checkbox. If the checkbox is unchecked before applying current edits, the prior HiQnet ID value will be restored.

All devices in the current ﬁlter view may be set to Random HiQnet ID by checking the checkbox in the column header — the individual checkboxes for

all devices will become checked. If any individual checkbox is subsequently unchecked, the column header Random ID checkbox will automatically

be unchecked. Conversely, if all devices in the current ﬁlter view are set to Random ID on and the Random HiQnet ID column header checkbox is

checked, all devices may be set to Random ID off by unchecking the column header checkbox — the individual checkboxes for all devices will

become unchecked.

NOTE: Devices are not discoverable at the IP level. A device which is not discoverable at the IP level (invalid IP address, etc.) will not be able to

report a HiQnet address. In this instance, the Random ID checkbox will be unavailable.

Displays the current discovery status of the device. The Status ﬁeld may not be edited. Discovery status hierarchy is as follows:

a� Discovered

If a device has a unique IP address and a unique HiQnet address, this condition will be shown unless the device is access controlled. When the

device is not selected, the "Discovered" label is represented in green.

The "Discovered" status is determined by the following conditions:

• The device is discoverable at the MAC address level.

• The device has a valid and unique IP address (manual or DHCP/Auto-IP).

• The device has a unique HiQnet address.

Page 29

CDi DriveCore Series Operation Manual

Installing Audio Architect & Conguring the Network

• The device is not access controlled.

b� IP Conﬂict

If a device has an IP address conﬂict, this error will be shown regardless of other status notiﬁcations. When the device is not selected, the "IP

conﬂict" label is represented in blue.

The "IP conﬂict" status is determined by the following conditions:

• The device is discoverable at the MAC address level.

• The device has an IP address that conﬂicts with another device which has already been discovered by NetSetter.

c� HiQnet Conﬂict

If a device has a unique IP address yet has a HiQnet address conﬂict, this error will be shown regardless of other status notiﬁcations. When the

device is not selected, the "HiQnet conﬂict" label is represented in red.

The "HiQnet conﬂict" status is determined by the following conditions:

• The device is discoverable at the MAC address level.

• The device has a valid and unique IP address (manual or DHCP/Auto-IP).

• The device has a HiQnet address that conﬂicts with another device which has already been discovered by NetSetter.

d� Locked

If a device has a unique IP address and a unique HiQnet address, this condition will be shown if the device is access controlled. When the device

is not selected, the "Locked" label is represented in yellow.

The "Locked" status is determined by the following conditions:

• The device is discoverable at the MAC address level.

• The device has a valid and unique IP address (manual or DHCP/Auto-IP).

• The device has a unique HiQnet address.

• The device is access controlled.

When a device has been discovered in a Locked state and any ﬁeld is attempted to be edited for the ﬁrst time, a dialog prompting for the Admin

password will appear. Only a successful login with the Admin password will enable all ﬁelds to be edited. This state may need to be reset on

rediscovery after applying current edits, requiring the Admin password to be entered again.

e� Discovering

This condition will be displayed if the device has had changes made to its IP conﬁguration or HiQnet address and HiQnet NetSetter is waiting to

re-establish connection. When a device being rediscovered is not selected, all ﬁelds within the device row are displayed but grayed out.

The "Discovering" status is determined by the following conditions:

• The device had been previously discovered at the MAC address level.

• Edits had been made to one or more ﬁelds.

• The device is being rediscovered after applying current edits.

NOTE: Since the sort order automatically updates when a ﬁeld within the sorted column is updated, the rediscovered device will occupy the

same row on rediscovery. The exception is when DHCP/Auto-IP or Random ID has been set prior to applying current edits, in which case the

rediscovered device will occupy the appropriate row in the current column sort order.

9� Device Type

The device class name is displayed here, as reported by the discovered device. To the left of each device class name, the brand icon is displayed.

The software application name is displayed for discovered PCs running an instance of HiQnet software. HiQnet software programs include System

Architect, Audio Architect, and Performance Manager.

display a "?" to indicate that the ﬁeld may exist but that the software does not have enough discoverability of the device to determine the value. A blank

ﬁeld or "-" implies the value is null.

12� Locate

The Locate feature allows a device to be easily identiﬁed within a network full of HiQnet devices. Clicking in the Locate column for a device will put

the corresponding networked device into a Locate state — the Locate icon will be displayed on-screen and something will happen on the device

to indicate the Locate state is active (e.g., an LCD or LED will ﬂash, etc.). Clicking an active Locate icon will disable the Locate state for the device.

Disabling the Locate state from the device will clear the icon. Devices may be put into a Locate state independently from selection so that more than

one device can be located at any one time.

Page 31

CDi DriveCore Series Operation Manual

Using HiQnet Audio Architect

Crown CDi DriveCore ampliﬁers have Digital Signal Processing built in. When using a CDi DriveCore amp, the loudspeaker processing (crossovers,

limiters, EQs, and delays) are in the onboard DSP, making discrete rackmount loudspeaker processing devices unnecessary. This drastically reduces setup

time, commissioning, rack space, and costs. The CDi DriveCore's internal DSP can be used to perform the following:

• Conﬁgure signal ﬂow

• Optimize system gain structure

• Conﬁgure DSP settings (set driver levels, crossover bands, delays, equalization, and limiting for your particular speakers)

• Conﬁgure output bridging, high Z/low Z operation, and much more

Much of the CDi DriveCore's DSP can be monitored and controlled from the front panel. However, additional control and functionality can be achieved via a

networked PC running the HiQnet Audio Architect software. The following sections describe how to start using Audio Architect to conﬁgure CDi DriveCore

Series ampliﬁers. For additional information on using Audio Architect, please refer to the Audio Architect help ﬁle.

Launching the Audio Architect Software

After launching Audio Architect, a prompt will appear if the

connected HiQnet devices are properly conﬁgured for the network

and discovered (see Figure 29). Checking the "Add discovered

devices to the Venue automatically" checkbox can save a step when

getting started.

Figure 29: Discovered Devices prompt

Page 32 CDi DriveCore Series Operation Manual

Using HiQnet Audio Architect

Ofﬂine & Online Operation Explained

Audio Architect has two deﬁned modes

of operation: Ofﬂine and Online. When

operating in Ofﬂine mode, system setting

changes made in Audio Architect will not

be reﬂected in the system hardware devices

in real time; ofﬂine changes must be sent

to the system devices in a second step, at

which point device settings will be updated.

Conversely, when operating in Online mode,

any changes made in Audio Architect will be

reﬂected in the system devices in real time.

When operating in Ofﬂine mode, the Ofﬂine

Design ribbon is presented at the top of the

Main Audio Architect window. From this

window, discovered devices can be added to

the venue by clicking on them in the Devices

tab on the left and dragging them into the

Room window on the right (see Figure 30).

Note that when a device is added to the venue, it is automatically removed from the "Discovered" device list. If the "Add discovered devices to the Venue

automatically" checkbox was checked upon launching Audio Architect, as previously mentioned, discovered devices were already added to the Venue and

this step is not necessary.

Each device added to the venue will have an IP address listed to the left of the ampliﬁer

image and a Name ID to the right (see Figure 31). The Name ID can be edited in the

Properties menu at the bottom of the window. The number to the left of the Name ID is the

HiQnet Device Address. The green circle indicates that the ampliﬁer has been discovered on

the network.

TIP: Double clicking a device image will open the device's Main Control panel (see

"Main CDi DriveCore Control Panel" on page 34 for more information).

Going Online

You will have to go online in Audio Architect before any changes can be made to device settings.

To go online:

1� From the Ofﬂine Design ribbon at the top of the Main Audio Architect window, click the Go Online

button. The Ofﬂine Design and Add Devices ribbons will now be replaced with the Online Operate

ribbon and, in some cases, the Match Devices ribbon.

2� When going online, the following scenarios are possible:

a� If one or more devices in the venue are not matched AND corresponding devices are available

on the network, going online lands in Match Devices mode.

NOTE: Before you can go online with a device, it must be "matched". See "Matching

Devices" on page 33 for more information.

b� If all the devices in the venue are matched, going online lands in Synchronize Venue mode. In

Synchronize Venue mode, and icons will appear for each device in the venue, Receive Send

as well as for a rack if more than one device has been added (see Figure 32). This provides the ability to send/receive data either to/from a

single device, or to/from all devices within the rack with a single click.

c� If no devices require matching or synchronization, going online lands in Run Venue mode. In this mode, Audio Architect is online with the

devices in the venue and real-time setting changes can be made.

Matching Devices

The Match Devices ribbon appears at the top of the Main Audio Architect

window after clicking on the button from the Ofﬂine Design Go Online

ribbon, then clicking the button from the Online Operate Match Devices

ribbon.

The Match Devices feature allows devices within the venue design to be

associated with the hardware devices on the network. If a device image in

the venue says "UNMATCHED", the device must be matched before it can be

associated and controlled with Audio Architect. This can usually be accomplished by simply clicking the button (see Auto-Match Venue Figure 33).

In the Match Devices ribbon, the following options are available:

• Networking

Clicking the button will temporarily take Audio Architect ofﬂine, then restart the network.Refresh

• Match

Clicking the button will automatically match devices on the network with the devices in the Audio Architect venue. Selecting a Auto-Match Venue

device then clicking the button removes the device's virtual connection with Audio Architect.Detach

• Editing

Clicking the button will undo the last change made and revert back to the previous state. Clicking the button will redo the last action that Undo Redo

was undone.

• Show

Any checked items in this section will be displayed alongside the appropriate devices in the Main Audio Architect window. The available items include

Device Names, Rack/Array Names, HiQnet Addresses, IP Addresses, Matched Indicator, and Unmatched Indicator.

Ampliﬁer Information

The Global Settings panel can be accessed by clicking the button from Global Settings

the Main CDi DriveCore Control panel (Figure 35 Figure 36). The Global Settings panel ( )

displays ampliﬁer information such as current ﬁrmware version, power supply temperature,

channel temperature, and more.

The following functions can also be conﬁgured

from the Global Settings panel:

1� Output Labels

These ﬁelds allow user-deﬁned names to be

entered for the analog output channels for

reference.

2� Front Panel Lockout

When turned on, the front panel controls

will be locked to prevent tampering. The

exception is the Power button, which will

remain functional.

TIP: The front panel controls can also

be locked directly from the front panel,

however, if the front panel has been locked

from Audio Architect, it must be unlocked

from Audio Architect. See "Security/Front

Panel Lockout" on page 66 for

more information on locking/unlocking the

front panel controls from the front panel.

3� Front Panel Blackout Mode

Turns the front panel display on or off.

4� Amp Status Port

Selects whether a 2Hz square wave heartbeat or +5VDC signal is sent to the Amp Status pin on the AUX port — either can be used to remotely

determine amp health/status.

5� Mute Input

Determines which output channels will be muted when using GPIO Input 1 (pin 3). By default, a high condition will cause all checked input channels

to mute. Checking the Invert checkbox will invert the polarity/functionality, meaning a low condition will cause all checked inputs to mute.

6� Fault Output

Inverts the polarity/functionality of GPIO Output 1 (pin 1). When checked, GPIO Output 1 will indicate an amp fault when in a low state, rather than the

default high state. See "System Protection" on page 72 for more information on faults.

7� Preset Recall Input

Loads one of two presets depending on the high/low state of Input 2 (pin 5) on the GPIO port. By default, these values are set to 0, which disables the

function.

8� Manual Aux Output

When this button is switched on, GPIO pin 2 (Output 2 ) will go high; when the button is off the state will be low. This provides a general purpose

output which can be used to control many external devices such as relays, indicators, PLC system controllers, or any other 3rd party device with logic

control inputs. This button can be controlled from its default loacation on the Global Settings panel, from a user-created custom control panel, using

logic functions in Audio Architect, or from a compatible HiQnet wall controller. The state of this button and the resulting output are stored/recalled

along with device presets.

9� Power Modes

Use these settings to turn the APD and ACD power saving modes on or off and adjust the behavior of the ACD feature. See "Power Saving Modes"

on page 71 for more information.

Conﬁguring Inputs & Outputs in Audio Architect

Assigning Input Sources in Audio Architect

All channels of the CDi DriveCore signal processing share a single Input Selector panel (shown in

Figure 38). From this panel, you can select the audio signal that will be routed to each ampliﬁer

channel and adjust the levels entering each channel's DSP chain.

The Input Selector panel can be accessed by clicking any of the buttons from the Main CDi DriveCore Control panel (see INPUT Figure 37).

1� Levels, Meters, & Clip Indicators

The level faders are used to adjust

signal levels entering the DSP chains

from the various input sources. The

meters in this panel display both peak

and RMS levels — the wider left meter

shows RMS level and the right meter

shows peak level for each channel. The

clip indicators light to indicate clipping

at the signal point just before the

loudspeaker management processing

(delays, EQ, crossover, etc.).

2� Input Selector Dropdown Menus

From these dropdown menus,

input channel assignments can be

selected for each channel. Analog

inputs are available for selection in

all CDi DriveCore amp models. Mono summed analog options are also available. Additional BLU link channel options are available in BLU link

CDi DriveCore amp models. When assigning BLU link channels, a second dropdown menu will appear, where the desired BLU link channel can be

selected, as shown in Figure 38. These BLU link channel assignment dropdown menus provide an easier method for assigning BLU link channels,

however, note that BLU link channels can also be assigned from the BLU link Input Channel Assignment window (see Figure 41).

3� Input Labels

These ﬁelds allow user-deﬁned names to be entered for the analog input channels, which can be used for reference and added to custom control

panels.

4� Input Conﬁguration and Output Conﬁguration Buttons

Clicking the button opens the Input Conﬁguration panel, where input levels and analog gain structure can be adjusted (see Input Conﬁguration

"Conguring Inputs" on page 37 for more information). Clicking the Output Conﬁguration button (available only in BLU link amp models)

opens the BLU link Output Conﬁguration panel, where the ampliﬁer's BLU link output channels can be conﬁgured (see "Conguring BLU link

Outputs" on page 38 for more information).

5� Triggered Source Selects Button

Pressing this button will open the

Triggered Source Selects panel (see

Figure 39). This panel makes it easier

to program a BSS Contrio Ethernet wall

controller to recall up to four source

selection states (Trigger A-D), along

with input gain settings and on-screen

controller labels. See "Programming

BSS Contrio Ethernet Wall

Controllers" on page 49 for

more information on using this panel

and conﬁguring Contrio wall controllers.

Using HiQnet Audio Architect

Conﬁguring Inputs

The Input Conﬁguration panel can be accessed by clicking the Input Conﬁguration

button from the Input Selector panel (see Figure 38).

The Input Conﬁguration panel (Figure 40) allows you to adjust signal levels entering

the ampliﬁer from the various sources. The BLU link CDi DriveCore models will display

additional BLU link (Network) inputs.

The meters in this panel display both peak and RMS input levels — the wider left meter

shows RMS level and the right meter shows peak level for each channel. Input Mute

buttons are available for each channel. Network Signal Status LEDs below each BLU link

input channel provide conﬁrmation of BLU link signal presence.

The Gain Mode option is used to set the maximum amount of gain the ampliﬁer will

provide. The available options are +26 dBu, +34 dBu, and +37 dBu. Note that changes to

this setting will affect all channels.

Clicking the button opens the Advanced Settings panel, where BLU Advanced Settings

link sample rate and mastership clock priority can be set. See "Conguring BLU link

Clock" on page 38 for more information.

If using one of the BLU link CDi DriveCore models, the button will be Audio Routing

available in the Input Conﬁguration panel (Figure 40). Clicking the Audio Routing

button opens the BLU Link Input Channel Assignment window (see Figure 41). This is

the traditional Audio Architect window used for assigning BLU link channels. From this

window, any available BLU link audio streams can be assigned to the CDi DriveCore's

inputs. Note that CDI DriveCore ampliﬁers provide an easier method for assigning BLU

link input channels directly from the Input Selector panel (see Figure 38).

Conﬁguring BLU link Clock

The Advanced Settings panel can be accessed by clicking the button from either Advanced Settings

the Input Conﬁguration panel (see Figure 40 Figure 43) or from the Output Conﬁguration panel (see ).

From the Advanced Settings panel, BLU link sample rate and mastership clock priority can be set. This

panel also displays clock sync status and BLU link input/output connection status. Input/output errors

and corrected errors are also displayed and can be reset from this panel. For more information on these

parameters, see "Conguring BLU link Settings" on page 22 "BLU link Status" on and

page 62.

Conﬁguring BLU link Outputs

Clicking the button from the Input Selector panel (see Output Conﬁguration Figure 38) opens the BLU

link Output Conﬁguration panel (see Figure 43). From this panel, audio source signals can be routed

("on-ramped") back onto the BLU link bus as follows:

• Pre-processed audio from the inputs can be routed to the BLU link bus.

NOTE: The audio from the analog inputs will still pass through the ampliﬁer input gain stage. This

means the signals will be affected by the Gain Mode setting and the Input Level faders located in the

Input Conﬁguration panel (Figure 40) before being sent out to the BLU link bus.

• Amp output channels can be routed to the BLU link bus.

NOTE: The output audio is bussed from a point at the end of the

amp's signal processing chain and includes the Transducer Thermal

Limiter. This is effectively analogous to taking the audio from the

physical output of the ampliﬁer, which feeds the loudspeaker, and

routing it onto the BLU link bus.

To route ampliﬁer audio onto the BLU link bus, select the audio source for

each output channel using the Audio Source dropdown menus, then select

which BLU link channel to route each signal to using the BLU link Channel

dropdown menus.

NOTE: Audio Architect also provides the traditional BLU link Output Channel Assignment window (Figure 44) for routing BLU link audio onto the BLU

link bus. Either method can be used to assign BLU link output channels.

Conﬁguring Amp Wiring & Output Modes in Audio Architect

The CDi DriveCore ampliﬁers are very capable and ﬂexible ampliﬁers. From the Ampliﬁer Mode

Settings panel, the following items can be conﬁgured:

• Inputs can be cascaded ("Y'ed") to multiple outputs.

• Output pairs can be bridged for mono operation.

• Outputs can be independently conﬁgured for Low Z or High Z (70V/100V) operation.

The Ampliﬁer Mode Settings panel can be accessed by double-clicking the button from the Main CDi DriveCore Control panel (see MODE Figure 45).

Cascading Inputs

The ability to cascade inputs (or "Y" channels)

makes the CDi DriveCore Series amps even more

ﬂexible. One input can be used to drive some or all

of the ampliﬁer outputs (see Figure 46).

NOTE: By cascading the inputs, the

corresponding input DSP functions for individual

channels will be removed and only the output DSP

functions will be available, as shown in Figure

47.

Figure 45: Mode button

Conﬁguring Outputs for Bridge Mono Operation

When more output power is required for

the application, output channel pairs can be

conﬁgured for bridge mono operation. This

can be conﬁgured in the Ampliﬁer Mode

Settings panel (see Figure 48).

When selecting the Bridge Mono option for an

output pair, only the odd-numbered input

channel will need to be wired.

NOTE: When conﬁgured for bridge mono

operation, only one channel in the channel

pair DSP will be available, as shown in

Figure 49.

Conﬁguring Outputs for Low Z/High Z Operation

The CDi DriveCore's output channels can be conﬁgured for Low Z or High Z operation. To

conﬁgure the ampliﬁer for High Z operation, select either the 70V or 100V option (see

Figure 50).

NOTE: If an ampliﬁer output channel pair is conﬁgured for bridge mono operation and

one of the High Z options is selected, the ampliﬁer output will produce 140V or 200V (rather

than 70V or 100V).

NOTE: When conﬁgured for High Z operation, a 35Hz

high-pass ﬁlter will automatically be applied to the

signal. When conﬁgured for Low Z operation, a 10Hz

high-pass ﬁlter will automatically be applied to the

signal.

Input/Output Delay Panels

The CDi DriveCore Series ampliers offer an Input (pre-Crossover) and Output (post-

Crossover) Delay for each channel. The Output delay is typically used for driver alignment

and provides up to 100ms of delay time per channel. The Input Delay provides up to 1 second

of additional delay time and can be used for delaying the system to the stage backline, delay

lls, or whenever more delay time is required than the Output Delay has to offer. Delay can be

adjusted in seconds, feet, or meters (see Figure 57).

The Input Delay panel can be accessed by clicking the button, and the Output Delay panel can be accessed by clicking the Input Delay Output D

button from the Main CDi DriveCore Control panel (see Figure 56).

LevelMAX Panel

The LevelMAX panel contains the entire LevelMAX suite of limiters, which consist of a peak

voltage limiter, RMS power limiter, and transducer thermal limiter (see Figure 59).

The LevelMAX panel can be accessed by double-clicking the button from the Main LevelMAX

CDi DriveCore Control panel (see Figure 58).

NOTE: If speaker tunings have been congured for a channel, the LevelMAX panel will not be available for that channel.

Available options/parameters:

• LevelMAX (Off, On)

Turns the limiters on or off.

• Mode (Auto, Advanced)

Sets whether certain parameters will be set automatically or available

for manual conguration. The following Mode options are available:

Auto Mode – When this option is selected, the software

determines the best settings based on the signal characteristics.

You can modify only the RMS Threshold, Thermal Threshold,

and Thermal Time Constant. All other parameters will be set

automatically.

Advanced Mode – Selecting this option allows the

parameters which are set automatically when "Auto" mode is

selected to be manually adjusted. This includes Peak Threshold,

Peak Release, and RMS Release.

• Peak Threshold (1 – 200 VPK)

Sets the peak level, in absolute voltage, which the limiter will allow

from the amplier. In Automatic mode, the Peak Threshold value is automatically determined from the dened RMS threshold and the low p

frequency dened in the crossover.

• Peak Release (0 – 10 seconds)

Sets the release time of the peak limiter. The release time is dened as the time it takes the limiter to increase the output signal by 20dB.

• RMS Threshold (1 – 400 VRMS)

Sets the RMS level, in absolute voltage, which the limiter will allow from the amplier. The RMS Threshold should be set to correspond to

term (2 hour) power handling of the transducer or system.

• RMS Release (0 – 10 seconds)

Sets the release time of the RMS limiter. The release time is dened as the time it takes the limiter to increase the output signal by 20dB.

• Thermal Voltage (1 – 500V)

Sets the long-term output power limit of the amplier to what the loudspeaker load can handle without overheating and going into thermal

compression. This is based on the AES power/voltage ratings of drivers outlined in the AES2-2012 standard.

• Thermal Response (1 – 600 sec)

Sets the time it takes for the thermal limiter to adjust output voltage. This is based on the AES power/voltage ratings of drivers outlined in th

2012 standard.

• Metering

These meters display levels in dBFS and include Amp Output (peak level on the left meter and RMS level on the right), Gain Reduction (pe

and total), and Thermal Limiting amount. The Transducer Thermal Limiting indicator lights to indicate the Thermal Threshold has been exc

NOTE: The LevelMax limiters include sidechain EQ for advanced speaker tunings. Sidechain EQ parameters are not user adjustable.

Using BLU link

BLU link is a digital audio bus found on the BLU link CDi DriveCore amplier models. BLU link devices are connected using standard Categor

higher cabling. This minimizes cable connections and reduces the amount of cable required, hence, cable cost. BLU link connections carry up to

channels of high-resolution digital audio at 48kHz, or 128 channels at 96kHz, both at 24-bit.

BLU link Specications

• Based on Gigabit Ethernet technology

• Up to 100m over CAT5e cable between each point (>100m using bre converters)

• 256 channels at 48kHz

• 128 channels at 96kHz

• 24-bit audio resolution

• Bus-like architecture — audio transmitted on a channel is available at all other devices on the bus automatically

• Wired in a loop for redundancy — recovers from a single cable break

• Up to 60 BLU link nodes (devices) can exist in a single BLU link system

BLU link Latency

Path Total Latency (for selected path)

Analog Input to Amplier Output 1.78ms

BLU link Input to BLU link Output (48kHz) 4.47ms

BLU link Input to BLU link Output (96kHz) 3.57ms

NOTE: Latency through the BLU link/analog mixed paths will be greater than the "Analog Input

to Amplier Output" path but less than the "BLU link Input to BLU link Output" paths.

Making BLU link Connections

On the rear panel of BLU link devices there are two BLU link ports: a BLU link input port and a

BLU link output port. Devices are connected together by wiring the output port of the rst device

to the input port of the next, then repeating for each BLU link device on the bus. If redundancy is

required, the last BLU link device on the bus should be connected back to the rst. This allows

audio to still pass through the BLU link ring when a single BLU link cable is compromised or

disconnected.

If ferrites were included with the amplier, they should be attached to the BLU link cables at the

back of the amplier as shown in Figure 74. If no ferrites were included, they are not required.

NOTE: Only connect BLU link ports to other BLU link ports. Connecting BLU link ports to

networking peripherals, such as an Ethernet switch or router, will not work.

See "Assigning Input Sources" on page 14 for information on assigning BLU link input

channels.

See "Conguring BLU link Settings" on page 22 for information on assigning BLU

link output channels and conguring the BLU link sample rate.

BLU link Port LED Indicators

Each BLU link port has LEDs that indicate the following:

Both Yellow LEDs On

This indicates the device is the BLU link master (meaning it's providing the clock for the entire BLU link

system).

The green LEDs light to indicate the port has established a link with the BLU link bus. If there are no cables

connected, the green LEDs will not light.

BLU linkIN OUT

One Yellow LED On

This indicates the device is slaved to the BLU link clock received from the connected device.

The green LEDs light to indicate the port has established a link with the BLU link bus.

BLU linkIN OUT

No Yellow LEDs On

This indicates the device is not receiving BLU link clock and will not pass audio. This either indicates the IN

and OUT ports are swapped (an OUT port is connected to an OUT port and an IN port is connected to an IN

port), or there is a mismatch between the BLU link sample rates of the amplier and the connected device(s).

See "Conguring BLU link Settings" on page 22 for information on conguring the amplier's

BLU link sample rate.

CDi DriveCore Series Operation Manual

Using BLU link

Mastership

The BLU link bus requires one device on the bus to act as master. The master will provide the clock for all other devices on the bus. This means

whole bus is synchronised to a single audio clock.

NOTE: The BLU link sample rate for all device's on a BLU link bus must be congured to match. By default, the CDi DriveCore amps are con

the BLU link sample rate set to 96kHz.

In certain cases, it is possible to incorporate devices of more than one Ethernet transport type (i.e., AVB, CobraNet™, or Dante™) connected wi

same BLU link system. In other words, if you’re careful, you can design a Harman system which actually includes two or more transports. For e

it’s possible for a Harman system to have CobraNet audio being converted to BLU link audio (BLU-800 and BLU-320 both have the ability to “

CobraNet to/from BLU link), which is then converted to Dante audio (BLU-806 and BLU-326 both have the ability to “bridge” BLU link to/from

depends on a given transport’s ability to “slave” (AKA “re-clock”) to a clock being generated by a separate transport.

Which transports support "slaving" to the clock of another transport?

Transport Supports Slaving to Another Transport

AVB No

BLU link Yes

CobraNet No

Dante Yes

The previous table has critical implications on system design when combining two or more transports. Any system based on Soundweb London

Architectural Media Systems) supports the multi-transport combinations shown in the following table.

Combined Transports Clock Master

BLU link + AVB AVB provides the clock

BLU link + CobraNet CobraNet provides the clock

BLU link + Dante Either BLU link or Dante provides the clock

BLU link + Dante + AVB AVB provides the clock

Any multi-transport combination NOT specically listed in the previous table is not allowed in Soundweb London systems (without being force

analog interconnects between transports). For example, BLU link + AVB + CobraNet is NOT allowed, because the AVB and CobraNet network

be synced to different clocks — their own.

Mastership is negotiated between all devices on the BLU link bus, and any change to the bus will trigger the negotiation to restart. The following

determine which device on the BLU link bus will become clock master:

• If there is only one BLU link device connected to CobraNet/AVB then that device is master.

• If there are multiple BLU link devices connected to CobraNet/AVB, then they compare master priorities.

• If there are multiple BLU link devices on CobraNet/AVB with the same highest priority, then they use MAC address to decide which is mas

• If there are no BLU link devices connected to CobraNet/AVB, then they rst compare master priorities. Next, if the priorities are the same, t

MAC addresses.

Fault Tolerance

When the last BLU link device in a system is connected back to the rst, the BLU link bus is capable of a degree of fault tolerance since each de

receives the same audio from two other devices. If a single cable connection is broken, the devices which are no longer connected will detect the

break: one device will detect that its BLU link in port is disconnected and the other will detect that its out port is disconnected. The devices will

route the audio so that it can again pass through the bus.

NOTE: When the cable is broken, the audio will take longer to reach its destination. This added delay is not compensated for in any way, but is a

effect of the way the fault tolerance system functions.

GNU General Public License Version 2

GNU GENERAL PUBLIC LICENSE

Version 2, June 1991

51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.

Preamble

The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to

guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most

of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is

covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too.

When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to

distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the

software or use pieces of it in new free programs; and that you know you can do these things.

To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions

translate to certain responsibilities for you if you distribute copies of the software, or if you modify it.

For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make

sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights.

We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or

modify the software.

Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software

is modiﬁed by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by

others will not reﬂect on the original authors' reputations.

Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually

obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free

use or not licensed at all.

The precise terms and conditions for copying, distribution and modiﬁcation follow.

TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

0� This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms

of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program

or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modiﬁcations and/or

translated into another language. (Hereinafter, translation is included without limitation in the term "modiﬁcation".) Each licensee is addressed as "you".

Activities other than copying, distribution and modiﬁcation are not covered by this License; they are outside its scope. The act of running the Program is

not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by

running the Program). Whether that is true depends on what the Program does.

1� You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and

appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to

Page 95

CDi DriveCore Series Operation Manual

GNU General Public License Version 2

the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program.

You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee.

2� You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such

modiﬁcations or work under the terms of Section 1 above, provided that you also meet all of these conditions:

a) You must cause the modiﬁed ﬁles to carry prominent notices stating that you changed the ﬁles and the date of any change.

b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be

licensed as a whole at no charge to all third parties under the terms of this License.

c) If the modiﬁed program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the

most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else,

saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of

this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not

required to print an announcement.)

These requirements apply to the modiﬁed work as a whole. If identiﬁable sections of that work are not derived from the Program, and can be reasonably

considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as

separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be

on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it.

Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to

control the distribution of derivative or collective works based on the Program.

In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage

or distribution medium does not bring the other work under the scope of this License.

3� You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2

above provided that you also do one of the following:

a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2

above on a medium customarily used for software interchange; or,

b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing

source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above

on a medium customarily used for software interchange; or,

c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for

noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b

above.)

The source code for a work means the preferred form of the work for making modiﬁcations to it. For an executable work, complete source code means

all the source code for all modules it contains, plus any associated interface deﬁnition ﬁles, plus the scripts used to control compilation and installation

of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or

binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself

accompanies the executable.

If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source

Page 96 CDi DriveCore Series Operation Manual

GNU General Public License Version 2

code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object

code.

4� You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify,

sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or

rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance.

5� You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the

Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program

(or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or

modifying the Program or works based on it.

6� Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to

copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the

rights granted herein. You are not responsible for enforcing compliance by third parties to this License.

7� If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are

imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions

of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a

consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all

those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from

distribution of the Program.

If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the

section as a whole is intended to apply in other circumstances.

It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section

has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people

have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up

to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice.

This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License.

8� If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder

who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is

permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License.

9� The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be

similar in spirit to the present version, but may differ in detail to address new problems or concerns.

Each version is given a distinguishing version number. If the Program speciﬁes a version number of this License which applies to it and "any later version",

you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the

Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation.

10� If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for

permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for

this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse

of software generally.

NO WARRANTY

11� BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY

APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM

"AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF

MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS

WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

12� IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY

WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL,

SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT

LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE

consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License

GNU General Public License Version 3

GNU GENERAL PUBLIC LICENSE

Version 3, 29 June 2007

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.

Preamble

The GNU General Public License is a free, copyleft license for software and other kinds of works.

The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU

General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all

its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this

way by its authors. You can apply it to your programs, too.

When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom

to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the

software or use pieces of it in new free programs, and that you know you can do these things.

To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain

responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others.

For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received.

You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights.

Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal

permission to copy, distribute and/or modify it.

For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the

GPL requires that modiﬁed versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions.

Some devices are designed to deny users access to install or run modiﬁed versions of the software inside them, although the manufacturer can do so.

This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the

area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit

the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future

versions of the GPL, as needed to protect the freedom of users.

Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-

purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To

prevent this, the GPL assures that patents cannot be used to render the program non-free.

The precise terms and conditions for copying, distribution and modiﬁcation follow.

TERMS AND CONDITIONS

0� Deﬁnitions.

“This License” refers to version 3 of the GNU General Public License.

“Copyright” also means copyright-like laws that apply to other kinds of works, such as semiconductor masks.

Page 100 CDi DriveCore Series Operation Manual

GNU General Public License Version 3

“The Program” refers to any copyrightable work licensed under this License. Each licensee is addressed as “you”. “Licensees” and “recipients” may be

individuals or organizations.

To “modify” a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy.

The resulting work is called a “modiﬁed version” of the earlier work or a work “based on” the earlier work.

A “covered work” means either the unmodiﬁed Program or a work based on the Program.

To “propagate” a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under

applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without

modiﬁcation), making available to the public, and in some countries other activities as well.

To “convey” a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer

network, with no transfer of a copy, is not conveying.

An interactive user interface displays “Appropriate Legal Notices” to the extent that it includes a convenient and prominently visible feature that (1) displays

an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees

may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a

menu, a prominent item in the list meets this criterion.

1� Source Code�

The “source code” for a work means the preferred form of the work for making modiﬁcations to it. “Object code” means any non-source form of a work.

A “Standard Interface” means an interface that either is an ofﬁcial standard deﬁned by a recognized standards body, or, in the case of interfaces speciﬁed for

a particular programming language, one that is widely used among developers working in that language.

The “System Libraries” of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major

Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement

a Standard Interface for which an implementation is available to the public in source code form. A “Major Component”, in this context, means a major

essential component (kernel, window system, and so on) of the speciﬁc operating system (if any) on which the executable work runs, or a compiler used to

produce the work, or an object code interpreter used to run it.

The “Corresponding Source” for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the

object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-

purpose tools or generally available free programs which are used unmodiﬁed in performing those activities but which are not part of the work. For

example, Corresponding Source includes interface deﬁnition ﬁles associated with source ﬁles for the work, and the source code for shared libraries and

dynamically linked subprograms that the work is speciﬁcally designed to require, such as by intimate data communication or control ﬂow between those

subprograms and other parts of the work.

The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source.

The Corresponding Source for a work in source code form is that same work.

2� Basic Permissions�

All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This

License explicitly afﬁrms your unlimited permission to run the unmodiﬁed Program. The output from running a covered work is covered by this License

only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by

You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may

convey covered works to others for the sole purpose of having them make modiﬁcations exclusively for you, or provide you with facilities for running those

works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or

running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any

copies of your copyrighted material outside their relationship with you.

Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it

unnecessary.
