The 3 Channel Audio Mixer is a basic passive audio mixer that combines the input of 3 3.5mm AUX stereo plugs into one 3.5mm AUX stereo output. The basic design allows for an effective mixing with zero additional power supply needed. Each input has a seperate volume control knob, as well as an output knob.
I built this because I wanted to be able to hear the output from my computer as well as my Switch and Playstation. The 3 channel audio mixer is perfect for combining your sources to a single output.
