Description
Audio Mixer
https://youtu.be/D-MEFECwNcs
This is a basic audio mixer intended for hobby experiments where a few audio signals need to be combined into a single output.
One example is mixing multiple audio synth tones together to create new sounds, or combining project sounds with an mp3 track.
Features:
- Uses an LM358 running on single 5V supply rail
- Has two stereo inputs (two identical three-channel mixers connected to Left and Right audio jacks)
- Has three 3.5mm stereo audio input jacks and one stereo 3.5mm output jack
- Input left/right/gnd header pins allow connecting inputs without audio cables
- Six on board trimmer pots allow level adjusting for each channel (intended only for infrequent level adjustments)
