I'm working with a CP 45 with the Cat 515 installed for split surround. When I generate pink noise through the 45 the right channel is alot lower than the left. I can't find any data about the Cat 515, but is the trim pot on that 515 card the output for the right channel? There's only one trim pot on the 511 board which would control the output for the mono surround. I haven't played with it, trying to find info first.

Thanks
Bernie

Yes, the trim pot on cat515 controls the Right surround output.

Is it independant of the one on the 511 board?

Yes, it is.

If you've got a level discrepancy, amplifier and speaker issued aside, look at the output level attenuator jumpers on the rear panel, above each output terminal.
