AI028 Voltage Controlled Matrix Mixer
The AI028 is a 6-input, 6-output voltage-controlled matrix mixer with 36 linear VCAs, allowing any input to be routed to any output with gain controlled by 0–5V CV. AC coupled; intended primarily as an audio matrix mixer. Available as a DIY kit or built and tested. No front-panel knobs — all crosspoint levels are CV-controlled exclusively.826
Capabilities 3
- Matrix Mixermatrix-mixer
- 6×6 voltage-controlled matrix mixer with 36 linear VCAs; any of 6 inputs can be routed to any of 6 outputs (A–F) with gain set by 0–5V CV at each crosspoint.826
- Mixermixer
- Each output (A–F) sums up to six VCA columns at unity gain.826
- Voltage-Controlled Amplifiervca
- 36 linear VCAs, one per crosspoint (Input 1–6 × Output A–F). Each controlled by 0–5V CV; 5V = fully open, 0V = closed.826
