1. Introduction
The DMC-842 is both an AES/EBU 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 switchable hi-end sample
rate converters offer a flexible clocking and further usage options.
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 flexi-
ble and most compatible AES42 interface available – a true milestone for the broad acceptance
of the new digital micropone technology.
