Trying to set up the Audyssey auto-calibration on my Onkyo TX-NR708, and having a problem.
It tells me to set my sub to 75 db. I have put my subs (I have 2x subs) on the LOWEST volume, and its picking up 81 db. With subs completely off, it picks up 47 db of subwoofer sound, even though the subs are both off.
If I continue and complete the whole Audyssey set-up, it configures all my speakers to 40hz crossover.
I'm guessing that the Audyssey chip/mic is damaged in the amp (it seems to be picking up LFE noise when it isn't there).
Is there anything I'm doing wrong, or do I need to give Onkyo a call?
