Hi,
I've built my first Soundskulptor MP573. I'm at the stage of plugging a dynamic mic in and getting an output that is mostly noise, a fizzy buzz, with a bit of the mic signal.
From the tests in the setup guide, I'm getting 25 Volts between V+ and TP2, I've done the biasing okay, so 3 volts between TP2 and TP4.
Jumper is on JMP3 and CN1,
Any ideas what to look for?
Thanks.
