and RB-DDA6S 6 Way Stereo S/PDIF Digital Distribution
Amplier
Introduction
Fig 9-1: RB-DDA6A/S Front Panel.
The RB-DDA6A digital distribution amplier is used for distributing digital
audio data in AES/EBU format, repeating both the audio data and the status
information of the input whilst re-normalising to standard digital audio levels.
It has a single XLR-3 female AES/EBU audio input which is distributed to 6 XLR-3 male
AES/EBU outputs.
Applications include distributing audio from a digital mixing desk to multiple digital
recorders, or feeding multiple studios with an output from a DAT machine.
It can accept input sample rates in the range of 30kHz - 100kHz, and bit rates of 16, 20 and
24 bit. So, it can be used for standard CD signal distribution at 16 bit 44.1kHz, as well as for
high quality 24 bit 96kHz recording.
The RB-DDA6S digital distribution amplier is similar to the RB-DDA6A except that it is used
for distributing digital audio data in S/PDIF format.
It has a single S/PDIF audio input which is distributed to 6 x S/PDIF audio outputs at the
same level and condition as the input signal. It can accept input sample rates in the range of
30kHz - 100kHz, and bit rates of 16, 20 and 24 bit.
Uses include audio distribution at 16 bit 44.1kHz from a consumer CD player to multiple
digital recorders, distribution of high quality 24 bit 96kHz signals from digital mixing desks
to recorders and connection of the output of, say, a DVD player to multiple studios.
