For the time being, I'm using a Sony AVD S50ES DVD/Receiver unit in my system. The speakers are Axiom's M22's, VP150, and QS4's. My sub is an SVS. I'm trying to calibrate my speakers using the Avia disk and RS spl meter. I can only do the adjustments using the pink noise in the receiver. It won't let me do the adjustments using the disk. When I start the test on my receiver, it cycles around each speaker doing the test tones. Now when I highlight level to do the adjustments, it will only let me adjust the center speaker, rear speakers, and the sub. Should I be able to adjust the front speakers? When I do the pink noise test, the fronts sound a lot lower than the rest of the speakers. I have to be missing something here on this receiver. Surely there is a way to adjust the front speakers. Thanks for any help.
