a few days ago i installed a new amp for my 2 front speakers.
when the installation was finished, i realized that the speakers were not
in phase, so i inverted the connecting wires at one of the speakers' connector.
all was fine until the time came for Audyssey calibration.
Audyssey said my front speakers were out of phase. i ignored the advice and went on with the calibration, knowing they were in phase.
what i would like to know is the reason this is happening; that Audyssey says one thing and my ears tell otherwise.
could it be that phase is inverted in the amplifier?
the amp is bridgeable, and i think that when an amp is bridged, one of the channels' phase is inverted; but the amp, as used, is not bridged.
it's used in stereo mode, and the only filter used is a 33Hz hi-pass.
anyone can enlighten me about this? i find it quite puzzling.
That is why I am not a particular fan of calibration. A few months ago I bought a brand new Yamaha CX-A5000 Pre-pro, great unit, however, when I did the calibration, it read that all but 1 pair of speakers(9.2)were out of phase which is ridiculous. It had me rechecking everything in my set-up including the cabling between the Pre-pro and amps, but, in the end, being pretty meticulous when I connected the new unit, and I hadn't changed any connections between the amps and speakers anyway, I knew there was nothing wrong.
My usual checking method(if you want to be 100% sure) is run a test tone just in the L/R speakers and when sitting in the sweet spot between the two and the tone is in the middle then you know everything is OK.
