CP4500 Stereo Bus Compressor / Re: Meter Light not working

« on: July 13, 2024, 03:21:49 AM »

Update for anyone that may experience the same issue.  Replacing Q1 and D18 did the trick.  Everything is working now.

Thank you JPK!

Try removing Q1 and D18.

That worked! Thanks for the help.

Does the needle move when you take the measurement?

Yes it does. It moved to just below the 8db mark.

First check that the meter is working by measuring its internal resistance (connector unplugged). This should move the needle. Around 600 ohms.

I'm not sure I know how to do this.  Do I just remove the unit from the chassis, and connect my ohm meter to the red and black terminals of the meter?

Hi.  I've tried to live without the meter working, but it's beginning to get to me. It's the same issue, the compressor works, the meter lights up, but the needle doesn't move.  I've checked that the meter connector is properly connected.  Also the meter worked for weeks before it stopped.  Is there something specific that I should be looking for?

Can you tell me what controls the needle on the meter?  I've replaced the meter and everything worked perfectly fine until a couple days ago.  The light is still working, however, the needle no longer moves.  I can hear the compressor working, but there is no visual feedback.  I'm wondering if one of the components burned out or something, but which one should I be looking at?

CP4500 Stereo Bus Compressor / Meter Light not working

« on: June 18, 2023, 01:22:14 AM »

Hey All.  I've put together the compressor and everything is working as it should.  I've already used it on a couple mixes.  The only problem I seem to have is that the light on the meter isn't working.  At first, it didn't even dawn on me that it had a light (must've skimmed over that part in the guide).  The In led works fine, it's just the light for the meter.

Any suggestions on specific things to look at?  Thanks in advance.
