My Pioneer 2011 I love to bits - BUT its autosetup seems to be not too great ! My left front speaker is nearer to the listener than the right - but a small amount - but due to room dynamics (stairs etc) - the left sounds quite a bit louder than the right - unless you correct it. YET - everytime I run the autosetup it puts the left hand speaker 2.5 - 3dB higher than the right - which is completely wrong. any ideas ? Or just autosetup a bit flawed ? The manual was a bit vague - I presume the circular based microphone - should be so flat base is on a flat surface - ie the microphone facing directly upwards ? Thanks for any help, Mark.
