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.
From a 3x3 to a 4x3 with an inverted input + the option to mod it with gain potmeters.

This project is open source. For all current design files, go here:
- 3 inputs + 1 inverted input
- 3 outputs
Each row has 4 potmeters for those 4 inputs which makes 12 potmeters in total.
The 3 inputs are normalised together for easy patching. The Inverted input can be used to subtract shapes from the mix.
There are some MOD possibilities:
- 3 Gain potmeter positions
- extra amplification stages for each input, useful for keying and feedback
