CGS switched matrix

This is just a quick, photographic guide for the one or two people out there that actually have the CGS122 switched matrix or CGS123 switched matrix Eurorack boards.

A little on how it works[edit | edit source]

Partial schematic. The rest is simply more of the same.

Construction[edit | edit source]

Switch PCB. Note that only half of the resistor positions are used. 1/8 W resistors are required. All resistors on this board are 100k 1%.
Switch PCB. Note that only half of the resistor positions are used. 1/8 W resistors are required. The second resistor position is for a second matrix on the same board, allowing for stereo switching. The CGS123 interface board is only mono.
