Behringer K900FX Parts.

I have a blasted unit that has mic input and line 1 working. Other line inputs and CD have no effect. I haven't been able to find a schematic for this unit. Checking the ICs I found data for the V4580M dual op amps from CoolAudio, but haven't been able to find any data even from CoolAudio on the V074M which I'm thinking might be where the channels are mixed. Does anyone know if this is some form of Quad amp or version of a TL074 possibly, or better yet where I might get a schematic, parts lists, etc.? Thanks.

Forget the V.
RC4580 & TL074.
Plain Jane op amps.

I agree with Jazz. 4580 and TL074, both very very common op amp ICs, and the Behringer people use them all the time.
