a 4×3 matrix mixer for LZX modular systems.

The Matrix Mixer is a DIY project for adding color control, feedback routings and advanced mixing to your system. The panel is 14HP and the pcb is low profile, 2.5cm deep, suitable for skiffs
Everything is through-hole. This build is considered suitable for ‘advanced beginners’.
The circuit is based on the ‘simple video mixer’ by L. Larsen, extented to a matrix configuration with extra’s. The design has evolved thanks to community effort. You can read about the progress here:

Use above thread as build pages. I’ll post the BOM and guide there soon.

This project is open source.
