Yes, I did!
Auto calibration, in my opinion,ÿis not always the best option. Recently I have auto calibrated my Yamaha AX761ÿand experienced
that FL sound was much weaker than the FR when playing CDs on 2 channel stereo, so I notched up the ÿFL by using the Level button
on the remote. Same goes for the surrounds sometimes I whack them up a bit if they are a bit too low.
