Electret microphone pre amplifier based ne5532 which is very simple and based on available today components. Audio circuitscircuits and schematics at next.gr. On this occasion, i will share the circuit for subwoofer filters in this subwoofer filter different from the previous filter or subwoofer module. It designed to connect a small electret microphone.
