Mic Mixer Circuit Diagram. However the output signal will have a dc offset because of the dc bias voltage which is not desirable. When looking at the circuit we have featured the use of a single integrated circuit lm348.
This circuit enables the user to blend in one 5 separate signals from 5 dynamic low impedance microphones and a couple of external auxiliary inputs which can be electret type microphones or even actually amplified inputs for example those from your cd player or a phone. The mic inputs are suitable for low impedance 200 1000r dynamic microphones. 3 ch mic preamplifier with mixer using lm348.
Thus microphone circuit is always followed by a mic preamplifier to balance the input signal which means to remove the dc voltage.
5 input microphone mixer amplifier circuit using a single ic. Audio schematics mixer circuits. 5 input microphone mixer amplifier circuit using a single ic. 2 line output combiner convert consumer equipment stereo signal to mono or combine audio signal from two different equipments to1 input.
