A-130-8 Octal Linear VCA
Eight independent linear voltage-controlled amplifiers (VCAs) with three summing mix outputs (1–4, 5–8, 1–8). Fully DC-coupled; suitable for both audio and CV processing.585
Capabilities 2
- Mixermixer
- Three summed mix outputs: channels 1–4, channels 5–8, and all eight channels (1–8). Mix output gains are reduced below unity to avoid clipping.585
- Voltage-Controlled Amplifiervca
- Eight independent linear VCAs, each with unity gain range 0–1. Fully DC-coupled; usable for audio and CV. Factory CV sensitivity 0–+5V, user-adjustable via rear trimming potentiometers.585
