ACA kit troubleshooting help

Absolutely. For the overall output test, I am connecting the negative scope lead to the ground bus bar (red inputs) and the scope probe to the black speaker terminal, for each channel.

Good, if you mean (outputs). What is generating the input signal? You're running into an 8 ohm load?

Yes outputs. I’m using a Analog Discovery 2 to generate the signal and two 8ohm non-inductive loads.

Your test setup looks good. Any progress with the Amp?

I FIGURED OUT THE PROBLEM!

I also feel like a complete idiot. The left side of my dummy load/speaker rig had a problem with it. Once I switched the amps output to the right/good dummy load all was well. Outputs are identical. Ugh!

Thank you all for the help! Sorry to waste your time.
