4. First Usage – Quick Start
4.1 Controls and Connectors
The front of the ADI-192 DD features nine buttons and 48 LEDs, providing all necessary means
for a detailed configuration of the unit, plus an optical SPDIF I/O with TOSLINK connectors.
INPUT MONITOR indicates a valid input signal separately for each digital input. Additionally,
RME's exclusive SyncCheck indicates if one of these inputs is locked, but not synchronous to
the others. See also chapter 5.1 and 11.2.
SRC INPUT defines source and frequency range of the sample rate converter's input signal.
In the CLOCK SECTION the current clock reference and frequency multiplier is chosen.
In the AES OUTPUT section, source, channel status and the optional sample multiplexing of
the AES/EBU outputs is selected.
TDIF OUTPUT defines which input signal appears at the TDIF output.
ADAT OUTPUT defines which input signal appears at the ADAT output.
The optical SPDIF I/O allows to use the first AES I/O port via TOSLINK cable.
The rear of the ADI-192 DD provides all the connections: eight AES/EBU (XLR), four ADAT
optical (TOSLINK), two TDIF (D-sub 25), three word clock (BNC), and mains power.
ADAT I/O MAIN (TOSLINK): Standard ADAT optical port.
ADAT I/O AUX (TOSLINK): Transmits further channels when sample multiplexing is active.
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.
TDIF-1 MAIN (D-sub 25): Standard TDIF port.
TDIF-1 AUX (D-sub 25): Transmits further channels when sample multiplexing is active.
WORD IN (BNC): A push switch allows to activate internal termination (75 Ohms). When termi-
nation is activated the yellow LED besides the switch lights up.
WORD OUT STD (BNC): Standard word clock output.
WORD OUT TDIF (BNC): Special word clock output for TDIF-based devices.
IEC receptable for power connection. The specially developed, internal hi-performance switch
mode power supply makes the ADI-192 DD 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
suppresses mains interference.
