Shaka-8 VC Stereo Matrix Mixer
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

Parameters 8
| Name | Type | Range | Behavior |
|---|---|---|---|
| Initial Level 1A | knob | -100dB – 0dB | Sets gain of Input 1 to Output A crosspoint. Maximum is unity gain (0 dB); minimum is -100 dB. Exponential/audio taper response. No boost above unity without CV.589 |
| Initial Level 1B | knob | -100dB – 0dB | 589 |
| Initial Level 2A | knob | -100dB – 0dB | 589 |
| Initial Level 2B | knob | -100dB – 0dB | 589 |
| Initial Level 3A | knob | -100dB – 0dB | 589 |
| Initial Level 3B | knob | -100dB – 0dB | 589 |
| Initial Level 4A | knob | -100dB – 0dB | 589 |
| Initial Level 4B | knob | -100dB – 0dB | 589 |
