Dj Audio Mixer Schematic Diagram. Let s add a matching circuit at every input to ensure that any signal source is not unduly. Let s make our mixer a little more sophisticated than a simple adder.
The power supply and audio power amplifier circuits are shown in figs 3 and 4 respectively. This is a universal 4 channel dj audio mixer project that may be customized and upgraded to 5 channel or even 10 channel level as desired by the user. 1 shows the block diagram of the audio mixing system along with the audio power amplifier while the circuit of the audio mixer along with a tone controller is shown in fig.
This audio mixer circuit uses an lm3900 ic but is not a profesional audio dj mixer.

The advantage of using the four op amps is that they only need a single power supply. This audio mixer circuit uses an lm3900 ic but is not a profesional audio dj mixer.
