Simple Audio Mixer Circuit Diagram. This is a very simple 4 channel audio mixer. Audio taper potensiometers are possibly much better but linear will do the job.
Audio taper potensiometers are possibly much better but linear will do the job. Block diagram of the audio mixer with bass treble volume and balance controls. I will also be demonstrating how resistors work by making a paper resistor.
This is the simple and low cost 3 channels mini audio mixer circuit diagram.
Here dual operational amplifier ic 747 ic3 is used for mixing several inputs without any mutual interaction. The ic has short circuit protection and wide common mode and differential voltage ranges. There are high low sensitivity switchable inputs for each input channel and each channel used low noise and high gain transistor of bc550c. In circuit a fet number 2n3819 is main it is better than common transistors that a high.
