What have you used to set levels on your rear surround (EX) speakers in a 7.1 system? I've got an Avia disc, but it seems that it only has test tones for 5 speakers plus the sub.
I REFERENCED Calibrated using Dolby Digital - "Explore Our World" DVD DD-EX HT Speaker & dedicated LFE Test Tones: .... a) Dolby Digital EX HT Speaker Test Tones = 75 dB .... b) Dolby Digital EX LFE Test Tone = 77 dB AVG (highest needle swing = 78 dB / lowest = 76 dB)
