Hi all, I have a couple AVIA questions. I am using it to calibrate my 5.1 system composed of an Onkyo SR600 receiver and Aperion speakers. 1) When using AVIA to find the "reference level" volume setting of your receiver, it appears that AVIA has a test to do this for each speaker and one that uses simultaneous pink noise of all speakers. Which do you use? 2) There doesn't seem to be any documentation on the frequencies used in the subwoofer frequency sweep tests. Anyone have any ideas what tones they use? thanks!
