I just got my speakers, and I want to calibrate them with my Ovation Avia disk. I have two questions. First, how do I calibrate the rear surround channels (it's a 7.1 setup). The Avia disk only has calibration tracks for 5 speakers. Second, I've downloaded the correction table for the Radio Shack sound pressure meter. But the Avia tones are "pink noise", not just a single frequency. How to I apply the correction to the Radio Shack meter? Thanks for your advice!
