I just got home from work...it's 4 am.....my new Onkyo M504 was delivered while I was away. I open it...it's beautiful....and the first thing I do is plug it in and hit the power button!! The needles pegged to the right at 500 watts......no servo light came on. Mind you I had nothing plugged into the amp yet! Online manual says...NO..NO!! So I turn it off...hook up my p 306 preamp and cd player.....turned on the pre first...then the amp.....needles pegged to far right again...no servo light...no sound.

Did I do something horribly wrong?
