The Aviom A-16CS Control Surface is a wired remote controller for the Aviom A-16R Personal Mixer (sold separately). With the A-16CS, the A-16R can be mounted in a rack with power amps, wireless transmitters, effects, etc., while still allowing a performer to have complete control over mix functions and presets. The user interface is similar to that of the A-16II.Each A-16CS can control one A-16R, connected by a single Cat-5 cable of up to 200 feet. Using the A-16R and A-16CS simplifies audio connections and provides two control points for a given mix. Includes one Aviom L-30 30' Cat-5e cable.
