Something is 'out of phase'. If you don't what this means look it up.

Perhaps the wires in the back of one of your speakers are the wrong way round?

pastor, you are describing a classical case of "something out of phase". On the channel strips of your mixing board, are there any buttons that have a zero with a "/" through it? If so, that is your phase inversion switch that many consoles have, as it is another very useful feature but only if you know how to utilize it. Now the problem with your general question is whether this is directly caused by a single microphone cable where 1 of the XLR microphone connectors has been improperly wired where pins 2 and 3 were reversed at one end? This is assuming that you're only using 2 microphones and 2 inputs?

If this scenario occurs when you're listening to something like a CD, brought up on 2 faders, that are not the same inputs as the microphones you are using, then the problem is probably within the wiring to and from your console or even possibly like jahtao indicated, 1 of your speakers may be wired incorrectly?

Most television engineers seem to have a 50-50 chance of getting audio wired out of phase, which they frequently manage. Broken microphone cables that have been repaired are another good source of frequent phase problems.

Nothing phases me! I'm always out of phase!
