Matrix Mixer

Abby designed two revisions of this custom 8 channel mixer used onstage with LCD Soundsystem. The mixer allows each operator to control their synth levels, two aux sends, and booth monitor levels.

This project was Abby’s first foray into designing a custom mixer.  Luckily, the spec was fairly simple, since it is a mono design, and it was meant to replace a very simple passive mixing setup.  Abby used state of the art modern op amps and a very clean SMT layout in this design. Initially intended for one member, the mixer’s backup units quickly ended up spreading across the stage to three total stations, resulting in a need to make four more backup units.  This allowed for a new revision, which made very slight improvements to the first design.
