Compact three channel mono mixer
MiX is a simple three channel mono mixer with a focus on compactness. Measuring only 2 HP, it can easily fit somewhere in the rack where there is leftover unused space.
The mixer features 3 inputs and a single output. Each input has a volume/attenuation knob. Due to the circuit's simplicity, the mixer can be used both for audio and CV signals.
