24-Bit/192kHz 8-Channel AES42 Interface for Digital Microphones

DMC-842 Front

DMC-842 Back

 The DMC-842 is both an 8-Channels AES42 interface as well as a controller for digital microphones. The unique device allows for connection and control of up to 8 digital microphones, and converting their signals to ADAT, AES/EBU, analog and (optional) MADI. Eight individually switchable hi-end sample rate converters offer a flexible clocking and further usage options, especially as the inputs are compatible to AES3 and AES/EBU too.
When developing the DMC-842, RME worked closely with the microphone manufacturers to secure maximum compatibility and best functionality. As a result the DMC-842 is the most flexible and most compatible AES42 interface available - a true milestone for the broad acceptance of the new digital microphone technology.
The DMC-842 is fully remote controllable, via MIDI, AES and (optional) MADI. The optional I64 MADI Card provides serial pass-through capability from one DMC-842 to the next (up to 8). All up to 64 audio signals are then available at the last device on one single line. Such a way of cascading is also possible with the Micstasy and the ADI-8 QS. The signals passed through the DMC-842 are available at the analog outputs, making an expensive splitter box on stage obsolete.

Overview of the DMC-842's most important features:

  • Fully compatible to AES42
  • 8 XLR AES42 inputs (AES3 compatible)
  • 8 balanced XLR Line outputs
  • 24 bit sample rate conversion switchable per input
  • Digital Phantom Power switchable per input
  • Supports Mode 1 and Mode 2
  • 63 dB gain range per channel, even in asynchronous Mode 1
  • LED level meter with 13 LEDs per channel
  • M/S de-/encoding
  • 4 x AES/EBU Out via D-sub, 8 channels @ 192 kHz
  • 2 x ADAT Out, 8 channels @ 96 kHz
  • Optional MADI I/O (I64 MADI Card) with serial cascading and digital/analog return path
  • MIDI I/O
  • Fully remote controllable
  • Future-proof by flash updates

MADI: Theory
MADI is the Pro Audio Industry standard for multichannel audio. The MADI standard was defined by the AES (Audio Engineering Society). Many factors have influenced the increasing importance of MADI in pro audio production systems. These include an overall growth in the use of digital audio equipment, and the ever increasing demand for greater ...
