Shaka-8 VC Stereo Matrix Mixer

Setonix Synth

Voltage-controlled stereo matrix mixer with all-analog signal path; 4 stereo input pairs, 2 stereo output pairs, exponential CV response per crosspoint, expandable via Shaka-4.589

Capabilities 3

Matrix Mixermatrix-mixer
4 stereo input pairs routed to 2 stereo output pairs via a 4×2 matrix of VCA crosspoints, each with individual CV control and Initial Level knob.589
Stereo Processorstereo-processor
All signal paths are stereo L/R pairs; gain is applied identically to both sides independently to preserve stereo image.589
Voltage-Controlled Amplifiervca
One SSI2164-based VCA per matrix crosspoint with exponential/audio-taper response; gain range -100 dB to unity (0 dB) from knob alone, up to +20 dB with CV.589

Jacks 20 — 16 in / 4 out
