4 Channel Power Amplifier Circuit Diagram. The two switch sw 1 and sw 2 is used to change the mode of operation i e. It produced too much noise and allowed clicks and pops from the power grid through to be amplified and heard.

I decided i was going to build a four channel power amplifier and later a pre amplifier to feed it. When switch sw 1 and sw 2 is closed the output is available at connector con9 and con10. This is a single channel audio amplifier circuit.

It has four channels and each channel can provide around 11w over a load of 2 ohms and around 6w over a load of 4 ohms.

About the circuit diagram for 4 1 channel amplifer the circuit discussed in this blog is based on a class ab type amplifier and is powered using single supply. Inverse classic and input object 2 channels pins 2 6. Lf power amplifier built on a chip tda7386. This is a single channel audio amplifier circuit.
