XLS 602 clipping

3 posts in this topic

I have a Crown XLS 602 that has a distorted sound at medium to high levels. Both channels work fine at low levels but at medium/high levels the positive side of the wave form clips. The clip lights do not come nor do the fault light. The wave form looks fine with no load. Please advise.

Sounds like a job for service. If you want to tackle this yourself, the schematics are available here: http://www.crownaudio.com/gen_htm/legacy/legacamp.htm

It would be best to call in for help if you are well into the job and can report with what you are finding in terms of in-circuit measurements. Then we can guide you better.

Thanks for the schematics. The problem was a resistor in the low voltage supply to the input opamps. I appreciate your help.
