Looking for a some help in designing an amplifier circuit for a electret microphone that will output audio to a pair of cheap o mp3 earphones.I want to be able to adjust the output gain from 1-1000.
Do i go for common emitter transistor amp or non inverting op amp ?
I want to have 3 pots to control the circuit with 1 to control volume, 1 to adjust what low frequency are filtered and 1 to do the same as the second but filter high frequency out ?
