FAQ
Having a hard time getting this to work. Is there a schematic of the board somewhere? (not the wiring diagram), would like to know how the left and right are connected, as I am only using 1 mic. Is it AC or DC coupled?
I'm getting a lot of output with the inputs grounded, and I'm not sure why.

Actually the left and right are almost same. they are both analog signal
