PCB and FR4 front panel (only) for a DC mixer synth module. This module is in LMNC's Kosmo format (20 cm high) and is 7.5 cm wide.

This is a DC coupled 3-input mixer, designed mainly for mixing control voltage signals. Slide pots control individual channel levels, an overall level, and a DC bias (offset) allowing outputs to be shifted up or down. There are both normal and inverted outputs.

User needs to source parts and assemble. (Photo of my own assembled module for illustrative purposes only.) Easy through hole construction.

Be sure to see the Github repository (linked below) for BOM, build notes, and other information.
