Bridge the Gap Between Broadcast Optics and Cinema Ergonomics

The ARRI LCUBE CUB-2 is a miniature signal converter engineered to bring the precision of broadcast servo-zoom lenses to professional cinema rigs. By converting analog Hirose 12-pin ENG protocols into ARRI’s digital LBUS standard, the CUB-2 allows camera operators to control broadcast-style zoom, focus, and iris mechanisms using advanced cinema accessories. It is an essential link for multi-camera broadcasts, documentary sets, and live event productions.

Empower Solo Operators with Precision Master Grip Control

When configured on run-and-gun packages, the LCUBE CUB-2 integrates seamlessly with ARRI Master Grips. This setup allows a single operator to keep hands firmly on the camera handles while executing smooth, organic focus pulls, iris adjustments, and dynamic zoom sweeps directly through the lens's internal servo motors. The need for bulky external lens motors is eliminated, drastically reducing setup time and rig weight.

Advanced Dual-Mode Iris Management

Operating in fast-changing lighting conditions demands instant exposure adjustments. The LCUBE CUB-2 features a dedicated hardware toggle that selects how the lens iris behaves. Operators can assign automated exposure duties to the camera using auto-iris mode, or instantly switch to manual mode to perform precise, smooth creative exposure adjustments directly from their handgrip wheel.

Compact, Field-Tested Broadcast Rigging

Built with ARRI's signature attention to rugged reliability, the ultra-compact CUB-2 casing withstands the mechanical stress of active, high-vibration camera platforms. The module includes an integrated mounting dovetail designed to interface with the LCUBE Bracket (K2.0009620) or standard 19mm/15mm Clamp Consoles. With its streamlined footprint and straightforward cabling, the CUB-2 integrates effortlessly on cameras ranging from heavy-duty studio configurations to agile shoulder rigs.
