Hi. I'm pretty noobish at anything technical, so forgive me if this is an easy question. I just noticed today that there is a pretty distinct tremolo in the in-house audio in one of my theaters (which is to say that you can't hear it in the monitor upstairs). Just from my audio background this would tell me a speaker is out of phase, but I don't know if that's the case with what I have here. Any suggestions? All I know to do is go around disconnecting speakers until I've found the problematic one.

is the monitor set to monitor amp out
It is possible that an amp is limiting itself or a driver has some issues
