8 x 4 matrix mixer

MatrixMix is like SwitchMix, but with knobs on - literally. Eight balanced inputs and four balanced line driver outputs in complementary pairs with a sealed conductive plastic pot and mute switch at every crosspoint. DC coupled for CV and audio applications or DC servo-ed for audio only.

Two may be configured for 8×8 or 16×4 operation. A similar stereo version, DuoMix, is under development.
