sonifex rb dda6a3 1

The Sonifex RB-DDA6A3 digital distribution amplifier is used for distributing AES-3id digital audio, repeating both the audio data and the status information of the input whilst re-normalising to standard digital audio levels. It has a single BNC AES-3id audio input which is distributed to 6 BNC AES-3id audio outputs.

Applications include distributing audio from a BluRay player to recorders, or feeding multiple studios with an output from a master clock.
It can accept input sample rates in the range of 30kHz – 100kHz, and bit rates of 16, 20 and 24 bit.
