This wired Advanced Remote Control (ARC) has been designed for direct access to the most frequently used actions and commands required in a studio's daily work. Its extremely flexible configuration through TotalMix FX will simplify the workflow and greatly increase the usability of the RME interface in any real world situation. The Advanced Remote Control (ARC) can be used with all Fireface UCX. It can also be used with all Fireface UFX with a serial number 23241707 (built after June 2011) or higher. Upcoming interfaces that feature an Advanced Remote Control connector will also be compatible. Users that own a Fireface UFX with a serial number below 23241707 have to send their UFX to their distributor as it requires a hardware modification to be fully compatible to the Advanced Remote Control. This modification is not free of charge. The ARC consists of a solid metal case with a main encoder dial, 2 push buttons and 6 LED-equipped buttons. The Remote Control connects to the main interface via a 5 m (16.4 ft.) cable and a special connector on the back of both units.
