Product Description Specification

Three Axes - All Inclusive
The Wireless Compact Unit WCU-4 combines three axes of lens control with a lens data display in a compact and ergonomic housing. Weighing around 780 grams including battery, it’s one of the lightest hand units in its class, providing unrivaled comfort during a long working day.

ALEXA Remote Control
An optional software license will enable you to remote control all ALEXA Plus type cameras, except the ALEXA HD Plus. This includes setting frame rate, shutter angle, exposure index, false color on the monitor output, and more. Extended camera status information is also available, allowing you to quickly check your camera settings at any time.

Vibrating Markers
Tactile vibrating feedback lets you keep your eye on the action in the most challenging situations. Operators can concentrate on the scene, knowing that the hand unit will vibrate to prompt them when focus markers are reached.

Backlit Focus Knob
The super-smooth focus knob contains an integrated light source that shines through the wide, optionally 
pre-marked focus ring in low light conditions, thus providing clearly readable focus marks at all times. 
The friction of the focus knob can be easily adjusted to one’s personal preference without any tools.

Easy-to-Read Lens Data Display 
Clearly arranged, easy-to-read lens and camera information is available on the large 3” display, along with 
data from optional ultrasonic distance measurement devices. The transflective display technology ensures 
perfect readability in all ambient lighting conditions.

Pre-Marked Focus Rings 
Lens scales can be mapped to a set of high quality pre-marked focus rings in metric or imperial scale.

Focus Tracking 
The WCU-4 user button can be configured to activate focus tracking - setting the focus motor to continuously 
follow a subject by using an ultrasonic distance measurer. Focus tracking works with ARRI's Ultrasonic 
Distance Measure UDM-1 and ALEXA Plus or Studio cameras or the Universal Motor Controller UMC-4.

Multiple Mounting Options
The Wireless Compact Unit WCU-4 features M4 mounting points on its top and bottom, and the optional 
WCU-4 Plate (K2.0006501) can attach to either, providing various 1/4-20 UNC and 3/8-16 UNC mounting 
points itself. When mounted on the bottom, the WCU-4 Plate serves as a table stand or can be used to accept 
a 3/8-16 UNC spigot for mounting on a C-stand. When mounted on top, it can be used to adapt the WCU-4 
to an on-board monitoring system. Weighing only 67 g, the WCU-4 Plate is made of durable, aircraft-grade 
aluminum.

Personalized Settings
Various parameters of the WCU-4 can be set up to one’s personal preference. These include the display 
arrangement, vibration patterns and programmable user button, to name just a few. You can save your 
preferred settings on an SD card, enabling you to immediately personalize any WCU-4, anywhere in the 
world. 

Exceptional Quality and Service
The WCU-4 is completely splash-proof and embodies the reliability and durability for which ARRI is famous. 
Wear and tear parts are replaceable at rental level, and the worldwide ARRI Service network ensures rapid 
second level support if needed. New firmware versions can be installed to the unit via SD card within seconds.
