Posted on Feb 5, 2014

Using a LM1458 dual op amp IC. The circuit takes the audio signal rom the condenser microphone and amplifier it, so you can use the microphone as the input to some device which wouldn`t normally accept microphone level signals. The circuit requires a 6-9 volt supply. Output of the microphone amplifier can be made variable by connecting a 10k © po
