The WCU-4 is compatible with the ARRI ALEXA Mini, ALEXA Plus, and Studio cameras, and with ARRI UMC-4, SMC-1, EMC-1, and AMC-1 motor controllers. Camera functions are controllable for ARRI ALEXA Mini, Plus and Studio, and ARRI AMIRA when used with the UMC-4 motor controller.

Vibrating markers and a backlit display make it easy to use the WCU-4 in low light levels. Multiple 3/8″-16, 1/4″-20, and M4 mounting points enable you to attach the controller to a rig when convenient.
