looking for pmh3000 behringer power mixer schematics

[alexclaire]

Hi everyone,

I'd like to find pmh3000 behringer power mixer schematics, in fact just power amp section.

I'm just curious about the way they implement class d topology in their power mixer.

I've just downloaded pmh1000 Schematics (N and P mosfet halfbridge for 200W/4 ohms)

can someone help me finding this schematics ?

thanks !

I have't once this unit for repair, not sch, but i remember it uses 2*IRFP640N with 4 diodes (paralel-series), drived by some integrated ic (like tc429, smd), optocoupled with some BP ic, feedback after the filter (20uh+1.5uf), many smd caps for decoupling vcc.

self-osc (aprox 500khz at iddle), half bridge..., +/-70v, photos soon....

 

[alexclaire]

Is it using different output stage than PMH1000?

 

[ionutgaga]

Yes, indeed; is totaly different...
Tommorow i will make some photos of this unit and i will atach to this forum. Just for curiosity... pcb is multilayer (maybe 4, but i'm not sure)

Savu,


I have a DPA300 power amplifier schematic that I can send to you but it is to large to post. If you can send me your email I will send you the PDF.
