Default Re: Avid 192 I/O question ???

Some of the info is here and some is incorrect.
There is a difference between the enclosure and the option card optical connectors.
The option card optical port only accepts 48kHz and will SRC to whatever session sample rate you are using. It also only outputs 48kHz. It has realtime sample rate conversion. It is also not switchable to optical SPDIF.

The enclosure optical port has no realtime sample rate conversion. It is also switchable to optical SPDIF (2 channel) instead of ADAT where it can go to 96kHz. However, in ADAT, it is also restricted to 48kHz.

Overall, ADAT on the 192 interfaces is restricted compared to other hardware makers who do >48kHz (DS/QS). I remember back when these were everywhere people thinking they were doing 96kHz just because their session was set that way but transferring via ADAT.

The Avid IO line of interfaces rectified this.
