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 SyncCheck indicates via flashing LEDs if one of these inputs is locked, 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 MONITOR section offers a 24 bit/192 kHz capable Line/phones output to 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.
