1. Introduction
With the ADI-642 you have an incredibly versatile digital interface to your supply. What at first
looks like a simple MADI/AES format converter, turns out to be a very flexible tool at a closer
look. From small project studios to broadcast and television, this A D Idvanced igital nterface is
the perfect solution for many tasks.
As a consequent continuation of RME's world-wide successful ADI series, the 642 also contains
elaborate technology and the latest integrated circuits. In a few words: The ADI-642 is a
uniquely powerful and high-quality device, which will excite you even after many years of opera-
tion.
2. Package Contents
Please check that your ADI-642 package contains each of the following:
• ADI-642
• Manual
• Power cord
3. Brief Description and Characteristics
The ADI-642 consists of two digital format converters in reference quality, in a standard 19" box
with 1 unit height. The compact device has numerous extraordinary features like Intelligent
Clock Control (ICC), SyncCheck, SyncAlign, SteadyClock, Auto Delay Compensation and
patchbay functionality with 72x74 channel matrix router.
All of the ADI-642 I/Os support 192 kHz/24 bit. The format conversion between MADI and
AES/EBU operates in both directions at the same time. LEDs of different colours show the pre-
sent state of incoming and outgoing signals and of the internal processing in a clear way.
The unique Intelligent Clock Contro e use with internal clock (44.1 up to l (ICC) allows for a flexibl
192 kHz), external word clock or the digital input signals. These options are intelligently coupled
in a way typical for RME, and easy to apply thanks to a clear and easily understandable display
of the Lock and Sync states.
Furthermore the unique 72 x 74 Matrix Router allows to use the ADI-642 as digital patchbay,
merger and splitter. All 72 input channels, MADI and AES, can be routed to all 74 outputs –
even within the same format.
A special Auto Delay Compensation mode realizes a sample-accurate input and output signal of
all AES/EBU I/Os, even when using multiple ADI-642s. The Auto Channel Assignment mode
lets you configure the matrix of up to eight units with a single key stroke.
The ADI-642 transmits both MIDI and RS232 invisibly within the MADI data stream, maintaining
full compatibility. The unit can also be remote controlled via MIDI.

4. First Usage – Quick Start
4.1 Controls and Connectors
The front of the ADI-642 features nine buttons, one rotary encoder, 38 LEDs and four seven
segment displays, providing all necessary means for a detailed configuration of the unit.
MADI INPUT determines the
current input for the MADI signal
(optical/coaxial). Additionally, a
detailed input state display
analyses and presents the input
signal status.
MADI OUTPUT is used to configure the MADI output as 56/64 channel or 48k/96k frame for-
mat.
AES INPUT STATE displays the presence of a valid input signal separately for each AES input.
RME's exclusive indicates via flashing LEDs if one of these inputs is locked, SyncCheck but not
synchronous to the others.
In the CLOCK SECTION
the current clock
reference and frequency
multiplier is chosen.
REMOTE defines the
source for MIDI remote
control operation (MADI
or DIN jacks).
The MATRIX section is used to configure the routing of all inputs and outputs. Auto Delay
Compensation (ADC) prevents offsets when using multiple ADI-642s.
The section offers a 24 bit/192 kHz capable Line/phones output to MONITOR monitor the input
signals.
The rear of the ADI-642 provides all the connections: eight AES/EBU (XLR), two MADI optical,
two MADI coaxial (BNC), two word clock (BNC), two MIDI (5-pin DIN), one RS232 (D-Sub), and
mains power.
MADI I/O optical: Standard MADI ports.
MADI I/O coaxial (BNC): Standard MADI ports.
AES/EBU INPUTS (XLR): Transformer-coupled, high sensitivity, therefore accepts SPDIF sig-
nals as well.
AES/EBU OUTPUTS (XLR): Transformer-coupled, fully AES/EBU compatible.
WORD IN (BNC): A push switch allows to activate internal termination (75 Ohms).
WORD OUT (BNC): Standard word clock output.
IEC receptacle for power connection. The specially developed, internal hi-performance switch
mode power supply makes the ADI-642 operate in the range of 100V to 240V AC. It is short-
circuit-proof, has an integrated line filter, is fully regulated against voltage fluctuations, and sup-
presses mains interference.

4.2 Quick Start
Configuration starts with choosing the MADI input, BNC or optical. The state of the input signal
is displayed by 14 LEDs. Shown are active input, automatic input selection, receiver state,
Sync, 56 or 64 channel format, 48k frame or 96k frame, and audio data within 8-channel
groups. The Sync LED shows the synchronicity between input signal and external/internal
clock, or between the active inputs.
The MADI output signal can include 56 or 64 channels (FORMAT). The FRAME key switches
the MADI output into native Double Speed mode (96K), in case internal or external clock allow
this mode to be activated.
In the AES INPUT STATE section, each input has its own SYNC LED. One LED per (stereo)
input signals audio information within the data stream. An AES/EBU or SPDIF signal in the
range of 60 kHz to 100 kHz will turn the DS (Double Speed) LED on. An AES/EBU or SPDIF
signal in the range of 162 kHz to 200 kHz will turn the QS (Quad Speed) LED on.
The source and frequency of the unit's clock is configured in the CLOCK SECTION. The button
CLOCK lets you step through the options external clock (AES, MADI, word) and internal clock
(44.1 or 48 kHz). The button STATE sets the range for the internal, but also the external sample
rate. Selecting DS will result in 88.2 and 96 kHz, selecting QS sets 176.4 and 192 kHz.
The ADI-642 can be remote controlled by MIDI commands. The button REMOTE is used to
select the source of the MIDI remote control commands, and also the destination for the ADI-
642's request replies. The standard MIDI ports or the MADI input and output can be chosen.
The matrix router is always active and allows to change the routing. First choose an output by
pressing the OUTPUT select key, then use the INPUT select key to select the desired input. An
input can be assigned to as many outputs as present (splitting), but an output can not be as-
signed to more than one input (digital mixing).
The button ADC activates the , which is very useful when using mul-Auto Delay Compensation
tiple ADI-642 in a serial connection setup. With activated ADC the Auto Channel Assignment
mode is also available, see chapter 7.6.
The ADI-642 remembers all settings before switching off, and sets them automatically when
switching on the next time. The storing process is triggered 4 seconds after the last change,
and is signalled in the display as quickly moving point.
