I have this MXA101 300w 12ch flat powered mixer a guy bought from ERUSA a few years ago. It won't engage the audio relay. Everything works up to the relay. No DC offset.
Looks like 6 transistors that are in some switching arrangement to close the relay. I can't find a schematic anywhere, even the retailer. The company XSS I emailed a few times and got nothing in return.
Cust said it went out when he enabled Phantom Power and never worked since. All Power sources are present, DC, bias, offsets look fine. Relay works out of circuit. It's just a basic 12V audio relay.
I tried other brands like Phonic (powerpod 1860) and found a print perhaps similar, but not really the same setup at all.
Anybody ever see one of these units?
