It is only stereo, but the behringer deq2496 does have digital in/out, so you can put it between your digital source and reciever, if you set your digital source to pcm only (not dolby digital). How often is your Music Choice thing in 7.1 anyhow?
It has one xlr digital in (which can be fed from an rca coaxial via an appropriate cable), and an optical digital in, and similar digital outs. The source must be selected on the unit, as there is no remote.
Sorry if this was already mentioned, but it didn't seem clear which behringer model people have been suggesting.
