User’s Guide DMC-842 © RME
The rear panel of the DMC-842 has eight AES42 inputs, eight analog outputs, mains power,
MIDI I/O, word clock I/O, the I64 Option Slot, and all digital inputs and outputs (AES/ADAT).
DIGITAL MICROPHONE – AES/EBU INPUTS (XLR): Eight balanced AES42 inputs with
switchable digital phantom power (DPP). These inputs are compatible to AES3 and AES/EBU.
ANALOG LINE BALANCED OUTPUTS (XLR): Eight balanced line outputs with up to +27 dBu
level.
AES I/O (25-pin D-sub): The D-sub connector provides four AES/EBU outputs and one
AES/EBU input (clock synchronization). The 25 pin D-sub connector is wired according to the
widely spread Tascam standard (pinout see chapter 18.9). The AES I/Os are transformer-
coupled.
ADAT OUT (TOSLINK): Optical ADAT outputs. These provide the same signals as the
AES/EBU outputs, but in ADAT format.
WORD IN (BNC): A push switch allows to activate internal termination (75 Ohms).
WORD OUT (BNC): Standard word clock output.
MIDI I/O (5-pin DIN): MIDI input and output via 5-pin DIN jacks. Used to remote control the
DMC-842, and – with installed MADI Card - to transmit MIDI data via MADI.
IEC receptacle for power connection. The specially developed, internal hi-performance switch
mode power supply lets the DMC-842 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.
With installed I64 MADI Card:
MADI I/O optical: Standard MADI ports.
MADI I/O koaxial (BNC): Standard MADI ports.
