i just finshed setting up my system. i ran the calibration test tone from my 970 and it seems to me that my 5 channel home theater needs no adjustment (just +1 debibal from my 2 surrounds). i set my sound level meter on 60 because the 970 test tone was rather low and all my speakers seemed to read the same on the sound level meter. is this normal or am I doing something wrong?
