Mic Preamp Circuit Diagram. The pinout diagram is shown below. In order to complete the circuit a simple audio amplifier is also designed.
In order to complete the circuit a simple audio amplifier is also designed. The circuit is an example of how a good preamplifier can be designed for dynamic microphones. Before we show the complete schematic diagram of the microphone amplifier circuit we will first show the pinout of the lm386.

Some circuits would be illegal to operate in most countries and others are dangerous to construct and should not be attempted by the inexperienced. A simple microphone preamplifier based on lm358 is designed in this project. The circuit is a simple two transistor pre amplifier using a feedback loop for enhancing the amplification. The circuit is very simple contains only few components and can be assembled in few minutes if all parts are available.
