A Eurorack 4x2 Matrix Mixer Module. It can be expanded with itself. Panel Inputs on the expanding module are "normalled" to the preceding inputs. Input normalling can be broken by plugging in cables into the expanding module.
Mixer schematic taken from bartinstruments.com's b:raid Matrix Mixer.
Production files can be found in production/BMMX.zip. A CPL & BOM file for JLCPCB is next to it.
Untested as of May 2026.
Production files for the panel are included (production/BMMX_panel.zip). Manufacture at JLC with black soldermask. Dark panel on front, silver panel on back.
