Hi
I purchased a second hand CP4500, it is very well built and mostly everything works/is calibrated perfectly. It's probably the best SSL style compressor I've ever heard and used (better even than genuine G Comp).
There is one small problem with the compression meter though...
Every now and again it's as though it is "stuck" at the zero position only moving very slightly like 1-2mm even though high compression is going on as expected. When this happens if I raise the level of the signal being fed into the compressor by a large margin it becomes "unstuck" and works as normal (for a while) even when the input signal is back to normal.
I should say this is only happening around 10% of the time it is in use.
It is compressing correctly and when the meter works it shows the correct amount of compression.
Could this be a mechanical problem with the meter itself or could it be the driver circuit? Are there any other components to look at which could be causing this?
Many thanks in advance.
