This is very simple and easy audio mixer circuit diagram can be build using few common electronic components . This audio mixer electronic circuit has two input channels . The input signal can be independently controlled using the R1 and R2 variable resistors . The R3 variable resistor offers possibility to fade out one of the signal while the other signal is fading in . The gain of the mixer is provided by the 2N3563 NPN transistor . The R4 variable resistor connected at the audio mixers output offer possibility to control the output signal volume .
