The V‑Series IrisX 12‑Key 1RU Rotary Expansion Panel enhances an existing IrisX control panel by adding 12 programmable rotary encoders in a compact rack‑mount form factor. Designed for seamless integration within the V‑Series ecosystem, it provides precise, intuitive control of continuous parameters such as levels, trims, timing, or positioning in mission‑critical broadcast, live production, and AV environments. The rotary expansion panel does not operate independently; instead, it relies on a primary IrisX panel for system logic, communication, and processing, enabling scalable, high‑resolution control while preserving a consistent workflow and avoiding duplication of core functionality.
