Electret Microphone Pre-Amplifier
This circuit will be useful if you have an electret microphone that
produces a low audio (sound) level and you want to connect it to an amplifier or
something like it. The circuit will boost the microphone output voltage to
obtain an acceptable signal level. Just adjust the R5 potentiometer to obtain
the desird gain. Note that the R5 value is dependent on your gain need.
