Overview 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.
