Circuits > Audio > Low impedance microphone amplifier Low impedance microphone amplifierDescription The circuit is a microphone amplifier for use with low impedance (~200 ohm) microphones. It will work with stabilized voltages between 6-30VDC. If you don't build the impedance adapter part with T1, you get a micamp for higher impedance microphones. In this case, you should directly connect the signal to C7. Schematic diagram
