Sound Mixer Circuit Diagram. This circuit is a simple mixer circuit. Diagram 1 0 shows the 3 channel sound mixer circuit using three norton opamps.
The image below shows a block diagram of the entire mixer featuring four input amplifier modules followed by four in out switchable tone control modules one stereo line input four mono main faders one stereo dual ganged main fader four pan pots a stereo main mixer amplifier module and two further tone control modules switchable in and out for each channel inserted before the main left and right outputs. This circuit is a simple mixer circuit. Audio mixer circuit fig.
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.
It can mix two signal channels and one channel is output. The power supply and audio power amplifier circuits are shown in figs 3 and 4 respectively. An audio mixer also called a mixing console is an electronic device for combining and modifying audio signals the modified audio signals are summed to produce some combined output signals. Digital mixing consoles use digital signal processing concepts and analog mixers are usually based on op amps electronic circuits.
