op amp 6 line audio mixer circuit


Posted on Feb 6, 2014

The mic inputs are amplified about 100 times or 40dB, the total gain of the mixer including the summing amplifier is 46dB. The mic input is designed for microphones with outputs of about 2mV RMS at 1 meter. Most dynamic microphones meet this standard. The choice of IC op-amp is not critical in this circuit. Bipolar, FET input or MOS type op-amps c
