This is a DC coupled, five channel mixer with attenuverters on each input. An attenuverter is a single knob that attenuate and invert a signal. It is expandable to ten channels by combining two PCBs.
The board features PC mounted pots, for less wiring and also mounting holes for flexibility. There are Eurorack and MOTM power connecters. It can be built in +/-12V or +/-15V systems without any modifications.
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 8HP 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.
