6 Ch Audio Power Amp Mixer Circuit

6 ch mixer circuit

IC = ua741
Below the mixer circuit 3 line inputs and 3 mic. The mic inputs are suitable for low impedance 200-1000R dynamic microphones. ECM or condenser mic can also be used but should have applied a bias resistor. As with any mixer circuit, a slight loss is always in place. The final summary must overcome a gain of 2 or 6 dB at them. Level of the input line should be approximately 200 mV RMS. The microphone inputs have increased over 100 times, or 40dB, the total gain of 46dB with the mixer. The microphone input for microphones, producing more than 2 mV RMS at 1 meter designed. Most microphones meet this standard.
