This is 5-input, 5 output signal routing module. Each input has a switchable inverter and each output has a unity gain mixer built in, so this module can be used as a buffer, inverter, mixer or differential amplifier while routing.
Toggles are PCB mounted for simple wiring. This module will work on 12V or 15V systems without modification
For complete descriptions of the way the module is used, and how to build it, including schematics and parts list; download this PDF file.
Boards are available now. Price for 1 PCB is $8.
Unfinished eurorack
panels are available for this project, they are 12HP and cost $8 each.
There is
more information here about panels. If you're interested in drilling your own panel for
this project, feel free to use my
drill guide. That image should be printed at 300dpi for proper
scaling.
