OK audio experts, I need your help. I'm not getting a signal from my 950 to my subwoofer (Paradigm OM-570). I've no idea why it stopped sending a signal - I don't think it's the sub. I unplugged the 950, but that didn't work. I don't want to reset it but if that's all that's left, I'll have to. Any suggestions? All other outputs are fine.
