Hello,

I couldn't find a definite answer to this after reading the manual and searching over internet. I figured that I would just ask.

When the Adat 2 in/out is set as an Spdif Optical, is it mimicking the AES in/out signal or does it become a completely separated Digital I/O. If it does then what becomes of the routing?

I'm asking that because I'm planning to add and main AD/DA convertor, an Antelope Pure 2, to my setup. My speaker are connected on the AES out of the Fireface 802 directly, which I'm monitoring the volume with my ARC USB and then I want to send the signal from the Fireface to the Pure 2 in digital for the DA conversion to my analog chain. From what I understand the AES and Spdif RCA are the same channel and I don't want the ARC volume to change the signal I'm sending to my DA. So I thought that the Optical Spdif through the ADAT 2 would be the solution.

Hope that makes sense ^^
