The Radio Remote Focus Unit (RRFU) provides a simple, wireless solution for remote control. Compatible with the ETC Express, expression and insight consoles and LPCs, as well as the ARRI finesse, focus and imagine 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.
