Installation Manual

Model M4840

THE DIRECTOR®

Features

Here are some of the features that make

The Director very unique, unlike any other

amplier:

• Digital and Analog Input Matrix

Each zone can select and play

any digital or analog input. The

high-resolution digital inputs accept

32-96 kHz, 16/24-bit digital signals.

The digital outputs can also play any

analog or digital input source.

• Ethernet Control

Via a browser or Telnet commands,

you can control and query almost all

the functions, mute zones, change

source inputs, recall EQ presets,

check line voltage, display protection

logs, and get an email if something

goes wrong.

• High Power Levels

The M4840 has 8 channels of 100

Watts each into 8 Ohms, or 200

Watts into 4 Ohms. Each channel

pair can also be run in bridged mono

at 400 Watts into 8 Ohms. Each

high-eciency amplier is made

from discrete components.

• Superior Sound Quality

Pristine sonics happens rst in all

AudioControl designs and is not com-

promised by any other feature.

• Unparalleled Energy Eciency

From the point of view of saving

electricity, the Director amplier has

no equal. It is VERY energy ecient

during operation, and equally impres-

sive during standby.

• Signal Processing

You have at your command: graphic

equalization, parametric equal-

ization, tweeter protection lters

and low frequency cuto lters. In

addition, you can set up any zone

with low-pass and high-pass channels

for a two-way setup. The equalizer

settings are ganged with left and

right channels together, or separate-

ly. Plus, there are six EQ presets per

zone to save and recall settings.

• LightDrive Anti-clipping

With durability in mind, AudioCon-

trol’s LightDrive anti-clipping pro-

tection defends the system against

clipping, distortion, damage, and

even teenage parties. The Direc-

tor features the latest evolution of

LightDrive which adds a power-sup-

ply-tracking instantaneous dynamic

control to the smooth sound of the

traditional AudioControl LightDrive.

• Self Resetting Protection Features

Protection features are extensive and

include thermal, short circuit, clip-

ping, ultrasonic and DC oset among

others. If the fault is removed, the

Director resets. Plus, it can send you

an email if something happens.

• Pacic Northwest Heritage

We make this product in the USA,

and we are very proud of that fact.

What is more important is the care

we craft in at every step, and the

extensive knowledge we have in all

aspects of the product. Plus, we back

this up with a conditional ve year

warranty.

Complimentary Features

for quick control of zones through

Telnet commands. Up to 4 groups can

be dened for control over Standby

and Source Selection.

• Exporting and Im-Import/Export:

porting of the amplier’s settings

– including EQ settings – has been

enabled. Now you can congure your

EQ settings as a template and apply

these to each Director M4840 ampli-

er in your system. A little rening of

those settings for each amp and you

will be in and out in no time.

Getting Started

1. Turn o power to all com-

ponents before making any

connections.

2. When making connections, des-

ignate red RCA plugs as right, and

designate white, black, or grey plugs

as left. This is a good idea for all sig-

nal connections made in your audio

system. The key is consistency. Stick

with the same color coding and you’ll

reduce possible problems.

3. Whenever possible, keep power

cords away from signal cables to pre-

vent induced hum. This is especially

important if you bundle the cables to

keep the installation neat looking.

4. Use quality interconnect cables. We

know from experience that really

cheap cables can cause a multitude

of problems. They tend to break

inside or corrode, causing a loss of

signal or hum. They also have poor

shielding.

5. If you need to run the RCA audio

cables more than 20 feet, consider

using an active balanced line driver

for the signals. This will provide

better noise rejection against nasty

things like hum, spikes, local talk

radio, and metaphysical paranormal

phenomena, etc. The AudioControl

balanced line driver components

(BLD-10, BLR-10 and BLX-10) are an

excellent way to send audio over long

distances with standard Cat-5 wiring.

Check them out at audiocontrol.com.

6. If you are using the digital inputs,

and running higher resolution sam-

ple rates (96 kHz), use high-quality

digital interconnect cables.

Getting Started

7. Dance in a fairy circle at midnight, on

the rst full moon of the new year.

Ask Queen Mab for the IP address.

8. Connect The Director to the network

with an Ethernet cord, preferably one

in good condition without a broken

tab or covered in Marmite®.

9. Open your favorite internet browser

and open the web server within the

unit. It will show all features and

controls of the unit.

Front Panel

Front Panel Features

1. Power LED – This dual color LED indi-

cates when the unit is in standby, on,

or o

Red: The unit is in standby mode

and is ready to be turned on

via Ethernet or 12V triggering

Blue: The unit is on

Green: Coee brewed

OFF: The unit is powered o

2. Protection LED – This red LED will

illuminate briey during turn on/o

phases, and if a fault is detected in any

amplier or the power supply (such

as overheating, over-current, or DC

oset). If a fault is detected, then the

unit will go into its protection mode to

prevent any damage to loudspeakers,

and to allow cooling.

3. Ethernet LEDs – These indicate the

status, readiness, and willingness, of

The Director’s Ethernet communica-

tions protocol to (getting all technical

for a moment) strut its funky stu. The

green LED glows when the Ethernet

is connected and operational, and the

yellow LED blinks during data activity.

4. Zone Status LED – This dual-color

LED indicates when the zone is in fault

mode, active, or in standby.

Red: The zone has detected a fault,

such as a DC oset or a load

short circuit.

Blue: The zone is active

OFF: The zone is in standby

5. Zone Level LEDs – These three LEDs

light from the bottom to the top

depending on the zone’s output level

(-33, -20, -10 dBFS). These LEDs can be

turned o using the rear panel switch.

6. Rack Mount Ears – The unit comes

supplied with removable rack mount

ears. These allow the unit to be rack

mounted in a standard 19” wide rack,

with a 2U height. Use standard rack

mount screws and washers to secure

the unit in a rack. The unit does not

have to be supported at the rear if the

rack is located in a xed location.

To remove the rack ears (making the

unit 17” wide), rst unplug the power

cord, and then locate and undo the

four screws securing each ear to the

side of the chassis, and remove the

ears. Replace the screws securely back

into the chassis. Do not remove any of

the other screws from the chassis or

top cover. There are hazardous voltag-

es inside the unit. Keep the rack ears in

a safe place.

Rear Panel Features

AC section

When rack-mounting the unit,

make sure that the power cord

and the AC power switch remain

readily accessible.

1. AC Input – Connect the supplied AC

power cord securely to this input. Plug

the other end into an AC mains outlet

of the correct voltage rating for your

unit. They are either 100 -120 VAC (50

– 60 Hz) or 220 – 240 VAC (50 – 60 Hz);

look at the check box to see how your

unit has been congured. The voltage

setting is not user-settable. This unit

is a class 1 device, do not defeat the

safety ground connection or use a

power cord that does not have the

safety ground pin.

2. AC Power Switch – This switch shuts

o the main AC power. Normally the

only time you need to turn this o is

if the system is going to be shut down

for an extended period of time. Use

the Ethernet or master trigger inputs

to switch the unit between standby

and on.

Also turn the power switch o during

lightning storms, wind storms with

frequent power outages, or when a

giant asteroid is heading for the power

station again.

3. AC Fuse – The main power supply fuse

may be checked or replaced. Make

sure that the power cord is unplugged

from the AC mains rst. Then use a

at-headed screwdriver to undo the

fuse carrier from the fuse holder.

Inspect the fuse and replace with the

exact same type indicated on the unit.

The use of any other type of fuse may

lead to an unsafe condition. If the fuse

blows again immediately, then unplug

the power cord and contact our ne

folks in customer service. Do not open

the unit, as there are no user-ser-

viceable parts inside, and dangerous

voltages exist.

4. Ground Isolation Switch – This switch

selects the level of isolation between

the audio signal ground and the AC

earth ground. In normal operation this

switch should be in the GND Ground

position. If there is trouble with an AC

ground hum, try the other two settings

for the best operation. For safety, the

chassis is always connected to the

earth ground regardless of the switch

setting.

5. Disable Front Panel LED Ladders –

The front panel LED ladders show the

output levels of each zone. If this is

distracting, or your pets or children

keep getting hypnotized, press this

switch in to turn o the LED ladders.

This switch does not aect the Power,

Protection, or Zone Status LEDs.

6. Master Trigger – If you are not using

the Ethernet connection to turn the

unit on, then you can use the TS 1/8”

connectors or the 3-pin block connec-

tor to turn on the unit or place it into

standby mode. Any one of these three

connections can be used as a trigger

input. For example, you could have

an external device such as one of our

glorious AudioControl home theater

receivers, turn on The Director when it

is turned on.

If you are not using the Ethernet

connection to turn on The Director,

and there is no trigger voltage present

at any of these trigger inputs, then the

unit will be in standby, with all zones

muted.

– This LED is blue when LED indicator

the master trigger input is active, and

o when it is inactive.

7. Ethernet LAN Port – This standard

port allows The Director to be connect-

ed to a 10BaseT network via CAT5 ca-

bling. The unit can then be controlled

using its internal web server, acces-

sible through standard and popular

(and some unpopular) web browsers.

No external software is required to

run The Director. See the section on

Internet Connectivity and Control for

detailed information.

8. Master Reset – If things are not going

well, for example you are unable to

communicate with The Director, press

and hold down this button for more

than 3 seconds. This will reset the in-

ternal Ethernet settings and other odd

things, and hopefully lead you along

the pathway to Ethernet communica-

tions once again. Warning: Do not do

this while turning on the power switch,

because all ash memory will be

erased, and the milk in your fridge will

go bad. In this case you will have to go

to the store and get more milk, and

inquire from our ne lads in technical

support about the latest rmware le.

9. Digital Outputs – These S/PDIF digital

outputs use standard RCA coaxial

connectors.

The digital signals from each of these

outputs can be a copy of any zone’s

input pair (converted internally from

analog to digital), or a copy of the dig-

ital inputs. This is selectable using The

Director’s web page interface. For an

example, these outputs can be sent to

the digital inputs of another Director

M4840 unit.

10. Digital Inputs – There are four

coaxial and optical digital inputs,

A, B, C, and D.

The digital signals are transferred

directly to the advanced DSP section,

and are then available to any zone or

all zones at the same time. The digital

inputs are selected for any or all zones

using The Director’s web page inter-

face.

11. Signal Present LEDs – These light

whenever a digital input signal is pres-

ent.

Zone Section

(All details are the same for each zone)

12. Zone Active LED – These will light

whenever the zone is active.

13. 12V Trigger Input – Indivdual zones

can be turned on by applying a +12Vdc

trigger voltage to these inputs.

14. Analog Inputs – These are line-level

analog RCA inputs. Analog signals

entering here from sources such as CD

players, DVD players, and TV outputs,

may be selected to play in this zone,

any other zone, all zones at once, and

the digital outputs. This extraordinary

exibility is made possible by taking

ballet lessons from an early age, and

The Director’s web server interface

menus.

15. Signal Present LED – These will light

whenever an analog input signal is

present.

16. Speaker Outputs – This 4-pin

connector allows easy connection of

two speakers for stereo operation,

or one speaker for bridged mono

operation.

17. Digital Loop Outputs – These optical

and coaxial digital outputs are copies

of the digital input signals. They can be

used to send the digital input signals

to other components in your system,

such as other Director units.

18. Analog Loop Outputs – These analog

outputs are copies of the analog input

signals. They can be used to send the

analog input signals to other compo-

nents in your system, such as other

Director units.
