Got this Behringer Europower PMP1000 mixer in for repair. Bugger to find a schematic for it. I managed to dig up something for a PMP3000 and that is close enough for the 1000.
Complaint: Microphone CH1 and CH4 not working. CH1 very low, CH4 no audio at all.
Fix: On this one it was on both channels a little SMD SOT-23 style NPN transistor with the marking K16. Audio goes through the PNP 1316 first and then through that offending SMD NPN. On the picture mic channel #1, board marking T10, next to D1.
Yeah, I know it isn't pretty and clean, but it's getting late and I am tired. It'll be clean and pretty tomorrow.
schematic = inside the PMP1000
PNP 1316 = 2SA940
A06 (MPSA06) = SMD marking K16 = DTC144ECAT
