When calibrating with Avia, just be aware that the tones are recorded 20db below reference. Hence you must calibrate at 85db. Most processors' tones are recorded 30db below reference. Hence you would calibrate at 75db.
Does it really matter what level the tones are recorded at, as long as they're all at the same level? After all, what you're calibrating to is parity among all the speakers, not an absolute level.
