Simple Microphone Amplifier Circuit Diagram. Microphone amplifier circuit with bass treble. This circuit will work very well with any type of audio amplifier.

The audio amplifier circuit needs 6 24v as per amplifier specification. Microphone preamp circuit circuit diagram. Now that you what each of the pins of the lm386 represents we can assemble the whole audio amplifier circuit.

Using transistors mosfet ic on a lot types.

Microphone converts sound into an electrical signal. So you will find extra humming noise in the amplifier. This circuit will work very well with any type of audio amplifier. We removed the 10k pot section and added additional bias circuitry of the microphone amplifier.
