Ive had my setup for a few months now and Ive used my complete surround system everyday since. Im pretty sure Ive gone thru the break in period and now have a problem. From the beginning Ive been told to get the calibration disc and SPl meter but havent only because I've been content with the way I had everything set. I will be getting it soon... my problem is this. Ive just noticed that my Left Main and Left Surround sound are a significant level lower than the rest. Ive checked all the connections and even switched the speakers and wires around and still have a lower volume on the Left Side. to fix this Ive set the both main and surround to apprx +8. Ive noticed this with the speakers in my hand, not mounted, no walls to cause any interference. Any thoughts?
