i tried to make this mixer circuit but im getting a quite bad noise problem. its a hissing, white noise like problem and very noticable. im using the tl074 opamp which is supposed to be low noise but didnt work any better than the 741. how can i cut down the noise? i think its coming from the mic amplifier section. is the schematic correct or are there important components missing?
