Behringer EM600 Echomachine schematics available?

Maybe I can get a programmed DSP from Behringer.

I wouldn't bet my life on that, but let's cross that bridge when we get to it.

But start with measuring voltages (not resistances, at least not yet); and see if you can also identify any voltage regulators on the board.

I have seen shorted voltage regulators in my professional life. Had a card with a 5V regulator sending out 15V. Plays havoc with logic circuits.

FYI.

Thanks! I was just making a folder of datasheets when this came in. Looks like most of the ICs on this are out of production. Big surprise.

Sorry mate,
But that will never happen.

It’s already quite hard to get some very simple parts from Behringer, like pots or encoders…

Also, i doubt the DSP chip itself needs any programming (i doubt it has any internal nonvolatile memory); the microcontroller that's running the show (ATmega 16A), on the other hand.....
