Ok as promised I would follow up and let you know how my rewiring went and if it solved the problem of same sound in all four channels.All of the wiring was correct if you are a psychopath, however for us regular folks it was whacked out man. First I traced the wiring from the cell to see what the hell they were doing. They had it wired all to hell but the main important thing is that it actually should have worked if not for one thing. You see they hooked up a CD player to the projector 2 inputs. That is correct. However for some damn reason they also hooked the same line from the CD player into the cell inputs through a standard light switch, this was so they could switch between CD player and projector and have it wired right there, instead of actually wiring the sound unit there (it is wired 15 feet away, go figure. This in and of itself shouldn't pose a problem, but I inspected the hookups a little closer. On the Cd hookup to projector 2, they did in fact crosswire left and right channels. This caused all of it to go mono as it was wired into the cell as well. I took out my trusty wire cutters and waited for the show to start. Cut the wires and DAMMIT we have stereo all of a sudden. My next project is to tear that whole damn thing apart and rewire the entire thing. Wires everywhere I tell you, its a mess. ------------------ "If it's not worth doing, I have allready been there and done it"

Yeah, we have a guy like that here, too.This guy used to own a recording studio near here (did several early Deep Purple videos.) He made a ton of money, sold his studio to spend more time with his kids. He came to the theater one day and was just asking questions. He thought we just set up a speaker behind the screen, and that was it. When he found out that we actually try to really EQ the place, he got real interested. He went out and bought his own R2 unit. We let him come in whenever he wants (during off hours) and play. He spends hours EQ'ing this way and that, many times for free. He has got some fantastic sound out of some auditouriums, especially 'problem' or odd shaped auditouriums. He sometimes forgets to put everything back befor the show that evening, but I usually catch it while threading. It's a small price to pay for such great sound.
