microphone preamp circuit


Posted on Feb 5, 2014

Here is a schematic of a very sensitive microphone preamp circuit, which can be used to increase gain of microphone or boost the audio signals coming from microphone. The circuit is very simple contains only few components and can be assembled in few minutes if all parts are available. This is a versatile mic preamp circuit and can be used for man
