I was sent the schematics, but it's only the overall block diagram of the whole mixer.

This amp sound good untill clipping, when it "cracks". No emi problem, regarding mix of decoupling caps, but 4 layer PCB. I havet a version of PMH5000 with IRF640N (unlike in the sch atached, with IRF640).
The opto-limiter is not so good with transient distorsion (cracks), but i have implemented a hard clipper, regarding suply voltage, just like in QSC PL6, with very good results.

Dear IO,
Would you please send a copy of schematics for PMH-1000 mixer?
Power surge destroyed something in the mixer section.
Thanks!

Hello Everyone,

I would like to test the output stage with an normal transformer before i buy a new SMPS supply. Thank you very much!
