ARRI DEH-1 Digital Encoder Head, Pro Set, OCU-1, Left Rocker

The ARRI DEH-1 Digital Encoder Head, Pro Set, OCU-1, Left Rocker delivers a streamlined and intuitive solution for remote camera control, ideal for users of the SRH-3 Stabilized Remote Head. This integrated system includes the DEH-1 Digital Encoder Head, the Operator Control Unit OCU-1, and a left-hand Master Grip with a rocker-style zoom control, offering an ergonomic and tactile alternative to joystick or handwheel-based operation.

OCU-1 Operator Control Unit

The OCU-1 is a compact, single-axis controller that allows camera operators to seamlessly override and return control of focus, iris, or zoom when working with a WCU-4 system. It also supports direct control of EF lenses on ALEXA Mini and AMIRA cameras without additional motors, and it can adjust the roll axis on the SRH-3 head. The unit features multiple mounting options including an integrated 3/8"-16 thread, a dovetail interface, or an optional rosette bracket.

Master Grip (Left-Hand Rocker)

The included left-hand Master Grip features an adjustable-speed rocker for super-smooth zooming, enhancing handheld or rig-mounted shooting. Designed with operator comfort in mind, it includes an integrated "eyebrow" shield to prevent accidental inputs and act as a finger rest. With FIZ control, run/stop functions, and customizable user buttons, the Master Grips are compatible with ARRI ALEXA, AMIRA, and select third-party systems. When paired with other control units like the WCU-4, the Master Grips enable collaborative operation with split FIZ control.
