The A1000 front panel display shows what speakers are active; i have a 7.2 setup with two subs connected to sub1 and sub2 pre-outs. The receiver NEVER shows sub2 in the display no matter what surround program i select. I noticed it does send signal to both subs but why the Sub2 nver lit up? Anyone has ever seen both subs lit up? I did used YPAO a couple of times with same results. I made sure i set both subs to ALWAYS ON before running YPAO. Is there a way i could manually enable sub2? The only option in speaker setup is to use a sub and nothing for sub2. Do i have a faulty receiver?
