BMC49. Attenuverting Mixer

picture of the module

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.

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.
