I'm have a Proceed AVP2 preamp, and checked the manual for any specs on the digital out and here is all that I found:
- 1 digital output RCA (S/PDIF electrical)
- Digital output impedance: 75? (S/PDIF electrical)

I know that I can run the digital out from the pre-amp to another digital-in on a receiver in another room and it works fine.

Trying to go to more than one room is the problem, I can't figure out how to "split" the digital out signal. There is 1 product I found that could work, the link is below, I just don't like the price very much.
