At the 976 the mains are set to small, the sub set to yes and crossover let at 80. I didn't change much from the default settings.

one sub is an Axiom Audio EP350 and the other is Eminence 15" powered by a bridged Crown XLS 1502.

The subs worked in this configuration and now they do not. Nothing has changed. Before it went in for repair, the subs would only work if the 967 received PCM audio. Now, they just do not work. If you go into the setup menu and run the test tones, nothing from the subs.

I hope this is just an isolated issue to this unit and it gets resolved. My concern is that it has been sent in for repair and it's doing it again.
