Phase Inversion
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 ? Pancake |

Any suggestions to straighten my mess out? Red to red, black to black "should" work. What is special about the center channel? Polarity inversion is a better wording to use.

Graham Done All front speakers seem to be in phase L and R Chanels are reversed on rear, and one is still out of phase. Can manage from here. Thanks Gentlemen !!!! Pancake |

Any suggestions to straighten my mess out ? Pancake Connect a portable speaker between the terminals of each speaker. The volume from (+) to (+) is lower than the volume from (+) to (-). The center channel is problematic because it's closer (in a rectangular room), it uses different drivers, and it plays a critical part in sound reproduction. It's important to get a digital control unit with automatic speaker calibration and manual fine tuning. Getting the time delay and EQ matched for each speaker makes the difference between a beautiful sound system and a clumsy one. If you don't have a digital control unit, some high-end DVD players have manual calibration for the analog 5.1 outputs. You'll have to go around the room with a tape measure and tinker with the controls for a while. If your sound doesn't take the path you think it does, the time delay adjustments will be off and you'll need a lot of walking around the room and tinkering to get it right. -- I don't read Google's spam.
