The RB-DDA6S 6 Way Stereo S/PDIF Digital Distribution Amplifier.
RB-DDA6S 6 Way Stereo S/PDIF Digital Distribution Amplifier
The RB-DDA6S digital distribution amplifier 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.
