ETC's Radio Remote Focus Units (RRFU and cRRFU) provide simple, wireless solutions for remote control. The RRFU is compatible with the ETC Express, Expression and Insight consoles and LPCs, Arri Imagine 3 and Focus consoles, and the Emphasis Control System. This small hand-held transmitter unit provides access to frequently used commands for dimmer and channel checks as well as macro and record functions. The small receiver unit plugs directly into and is powered by the RFU port on the console or nodes. The equally convenient and powerful Congo® Radio Remote Focus Unit (cRRFU) is compatible with ETC's new Congo console system and provides comprehensive control functionality.
