CP4500 Stereo Bus Compressor / Re: CP4500 Threshold doesn't work

« on: March 22, 2023, 09:42:17 AM »

Hi JPK,

I fixed it! Thank you so much for your help. I renewed all solder joints around that area but I think it was a slightly deformed pin of the U21.
Thanks again and have a good day

Yes, that works fine. So the pot is working.

Thanks, I've checked it, and it's just 0.45 to 0.55 VDC, when I turn the threshold. The solder points are good... is there another way to check out if it is the pot?
Thank you

CP4500 Stereo Bus Compressor / CP4500 Threshold doesn't work

Hello,
today the Threshold Poti of my CP4500 stopped working. I can turn it as usual, but it has no effect on the signal. Yesterday everything was fine, so I have no idea, why it stopped working. Any solutions?
Thank you!:D

Hey,

today I checked everything again and the problem was not the CP4500 but a faulty channel of my lunchbox.
Now everything works fine...
So thanks for your time and sorry for wasting it a little.

Have a nice day!

CP4500 Stereo Bus Compressor / Stereo image changes

« on: October 28, 2022, 02:10:30 PM »

Hello,

I didn't find a match in the topics, so I start a new one 
After the build the CP4500 works very fine but since some days I had a strange issue:
when turning zu Threshold down, the stereo image changes to one side and the other one just has a very low signal.
I turn it to -15db - it pans to the left side, when I bring the makeup-gain in, I can bring the level of the right side back to level match.
It seems like the threshold and the makeup-gain knobs working like panning-knobs?!?

Can you please help out?
Thanks so much.
Chris
