I have an Onkyo 706 Receiver and would like to run the test tones
through all of the speakers as a stand-alone test without having
to run through the calibration/setup process. Is that possible and
how would I do it?
Reason: No sound is coming out of rear center speaker. It used to
but I had to disconnect it during the Holidays and now I do not get
any audio from it and I want to be able to run the test tones.
