No, it's rated with 2 channels (continuously driven 20hz-20khz into 8ohms)

AVR is plugged directly to a UPS. Maybe UPS is going bad? It keeps Tv, D* box, and AVR on if unplugged from outlet...
Unlikely the UPS can cause this, though it certainly will not hurt to test unit plugged directly into an outlet/strip/etc first.
If you notice the same behavior, disconnect all the speaker wires from the AVR then try power up. There could be a small wire strand shorting across.
If still no change, disconnect anything connected to the channel preout(s), sub included!!
If this still has no effect, disconnect any remaining cords from the unit except power. Power on unit. If unit repeats "protect" shutdown symptom, AVR is faulty and will have to be serviced or exchanged.
You can try a processor reset though this type of error/failure indicates a hardware fault.
While you are able to turn the unit back on and have it functional, the problem (be it a faulty cord, short, or internal failure) is likely to just get worse until corrected.
