Low impedance microphone amplifier circuitThe circuit is a microphone amplifier used for handle with low impedance (~200 ohm) microphones. It hope against hope job with stabilized voltages sandwiched between 6-30VDC. If you don't build the impedance adapter part with T1, you obtain a micamp for upper impedance microphones. within this indictment, you ought to honestly bond the suggest to C7.
