This module rectifies an input's positive and negative voltages and outputs them to separate jacks so they can be processed separately. The signals can then be returned and mixed back together in the re-combiner section. The re-combiner's inputs have their own rectifiers built into them so it can also be used to mix together different signals while preserving the polarity difference.
This module is designed for Eurorack style systems and has PCB mounted 3.5mm jacks, but includes mounting holes and a MOTM style power connector on the PCB so it can be adapted to other systems. It will work on +/- 15V systems without changing any resistor values.
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 4HP and cost $7 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.
