Transistors Got Audio Mixer Circuit With Lot Of Noise

Mar 08, 2020 Your first circuit has different gain for some inputs. IP 1 and 2 are the same, and IP 3 and 4 are the same. Your second circuit doesnt do anything to explicitly set the gain - it amplifies for all the transistor can give you. Itll happily amplify any noise on the inputs to a crazy volume. I expect the real problem isnt noise.
