On some of our CP-500's the volume on the non-sync doesn't change no matter what I do to the trimpots on the non-sync board. Any suggestions?

There is a way to edit the format itself so that it kicks in at a preselected overall fader level. It's in the manual.

I only have one of these machines and I rarely have to fiddle about with it so I'm sorry I can't be more detailed than that.

Use the trimpots as a means of getting a good preamp level and also to balance left/right signals.

Forget about soft controls - if the level doesnt change with the pots you've either got a faulty CP500 (unlikely) or an alternative signal path (most likely an earth loop) somewhere. Try using NS2 - same problem ? How are the RCA's wired ? Are you linking the CP500 signal ground to real earth ?

What happens if you connect to an acc rack input ?

We've found isolation transformers vital when we start to get too clever and link too many things to the CP500 (cpxx)

Good luck - let me know what happens

Yeah. Forget about them. It was rather naive and silly of me to even suggest it. [Roll Eyes]

You are right, Peter. I have never seen a faulty CP500. These units just don't have technical problems.

Manny, it is your refreshingly naive character and entertaining silliness which makes you so endearing to the members of this forum. BTW, how come you look completely different in each of your pictures?

Ummm...I've wondered about this myself. I don't know who those people are. I don't ever remember sending in a member photo. [Eek!]
