Hi guys,


Someone who has the qsound amplifier could share pics of the PCB on both sides, I want to draw the schematic to see if it is just a common amplifier or has something else. If in the photos you can read the values of the components much better.

Thanks!
 
I saw it and that's what aroused my curiosity. Unfortunately the photos they have are not very helpful
 
I can take some pics tomorrow. PM me to remind me.

it's just an amplifier, there's no special processing or anything else going on.
you can see photos of the underside here: Capcom Q-Sound amp help?

while not good enough to draw a schematic you can see that the underside of the PCB isn't hiding anything either.

Apparently the opamps are configured in a special way:

Does the Amp have more than 2 channel output?

I don't see how it would be Matrix Decoding unless it did. unless the "Stereo" output from the PCB isn't actual stereo
 
I was lucky. I bought a cab with one inside it. Even though the amp had been bypassed they still had left it and the transformer inside the cab.

Anyway, I did a set of pics with rectilinear correction and one layered pic:

Have at it.
 
Nem thank you very much for the photos! as soon as I get out of work I'll start to draw the schematic.
