AUDIO AB SELECTOR WITH GAIN CONTROL

Explore the innovative technique of virtual masses, where signals don't pass through the switch, but the ground takes on the role of "Mute/De Mute." This project features clever circuitry using OP amplifiers and resistors to seamlessly switch between microphone and line inputs, with a built-in gain compensator for maximum control. Read on to learn how this project can also serve as a clever By Pass function for your audio effects!
