Hey Nick,

I seem to recall the OA12 cards having jumpers on them to determine which speakers they will output (front vs rears). You could double check the jumpers, or perhaps they have to be in a certain order in the 861v4, maybe try swapping the positions of the two cards? Is the volume jumping on speakers from both cards or just one?

When I was running my analog front speakers, I temporarily hooked up some DSP5200's to demo them for a sale. I remember having alot of trouble configuring the system to get the DSP speakers to work and OA12 was still putting out REALLY loud sound when it was supposed to be coming out of the DSP's. I think I ended up having to take out almost all the cards to get it to work. Perhaps there's an issue with the config program when switching from analog to digital configurations, could be worth starting from scratch?

I have a spare OA12 in the garage (and a currently unused one in my 861v4). Let me know if you can't figure this problem out and want to borrow them to confirm it's not a problem with your OA12 cards.

Thanks,
Chris
