Dynamic Mic Compressor circuit diagram

The circuit below is aDynamic Mic Compressorcircuit is simple but the results are quite satisfactory. Audio output sounded outstanding. The principle of this circuit is very simple, the first transistor is used as Mic Pre-Amp. Then a second transistor used as a buffer. And the third transistor is a feedback circuit.

Supply voltage of thisDynamic Mic Compressorcircuit must be 12 Volt. Highly recommended to use its own power supply, do not use a shared power supply from another electronic circuit module.
