Audio Gambar Skema Condenser Microphone Amplifier


Posted on Feb 6, 2014

The amplifier has an adjustable gain, which is performed by. R1 (a 1 Mega Ohm variable resistor). It controls the feedback of the 741 opamp, which in turn drive a 2N2222 output transistor. The circuit takes the audio signal rom the condenser microphone & amplifier it, so you are able to use the microphone as the input to some device which wouldn`t
