Craig, I am trying to help a friend of mine calibrate his system. I used an SPL meter but the problems are: 1. I dont' think you are able to isolate the test tone on any one speaker. It constant cycles through every speaker which is not a huge problem 2. The surround speakers don't seem to be able to be controlled separately. I am not really familiar with this model but I can tell you what we tried to do.
I leveled all of his speakers to baseline, and turned up the master volume until the left front speaker registered 75 dbs. Then I bumped each individual speaker until they also read 75 dbs. The problem lies with the surround speakers due to the fact that I was unable to calibrate them serparately. The only thing I can think to do is make sure he has the distances from each speaker to the listening position put in properly. Any suggetsiions?
There should be an balance option for the surrounds on the setup. This will let you adjust their relative levels. On my (lower model) Sony, the balance works as a volume cut so you need to adjust the balance so their levels are the same and then adjust the surround's level back to your reference level.
If the receiver tones are cycling too quickly (yes, you can't control that), try getting hold of a setup DVD like AVIA, Video Essentials, The Ultimate DVD.
