Got a bunch of amps and speakers in a Home Theatre Hifi Setup, usta be
real easy to keep everything in phase with a simple stereo. Now I have
5 power amps, and not sure which ones flip the phase 180 degrees from
in to out. Not to mention the center channel that sounds out of phase
with the front main left and right channels. Any suggestions to
straighten my mess out ?
