API 7600 compressor problems

Hey guys,

I just purchased an API 7600 for a very good price. The previous owner says that it worked fine, but I found a serious issue with the compressor. When I turn the ratio just past 0, the compressor crushes the signal. This is with the threshold at +10 and a very low level on the mic pre. Also, even when I have no signal going through the box, when I turn the ratio knob just past 0, you can see the GR meeter go down. The more I turn the ratio up, the GR meeter goes further down...yet again, with NO signal.

I'm about to call API to see about a repair, but I wanted to know if anyone else had this problem.

Any help would be greatly appreciated.

I have two that I also bought second hand. I'd suggest it needs to be serviced... Never experienced that before. I'll double check tomorrow if anything happens when no signal is being passed and the knobs are turned.

Once it works the way it should- you'll love it. I want two more. :-D

Is the comp actually crushing the signal, or is the meter just reading wrong?
