How to make my dynamic mic pre-amplifier circuit work?
I found this circuit and tried to apply it, I didn't get anything at all, but the surprising thing that when I connected an electret mic, it worked like a charm !
So, what is the problem I'm missing !
if anyone have any Ideas or better circuits for my purpose please feel free to give any ideas, thanks :)
Note : even the electret mic didn't work before I canceled the capacitor after the mic input, I'm using uA-741NC @ 12V.
