Audio Voice-Over Circuit using LM380


Posted on Feb 5, 2014

This circuit is a circuit diagram of a microphone preamp and circuits (voice circuit) has priority over any other audio signal. In its simplest form, the voice-over only the microphone unit and the change-over switch eating an amplifier, the output of the microphone has priority over the amplifiers audio signal when the push-to-talk switch is pressed
