Electro-Voice RMA - Rotating plate for MB…UMH/TMA mounts with vertical rotation up to 45° in 5° increments

The Electro-Voice RMA is an installation accessory that acts as a rotating plate between the loudspeaker and the MB…UMH family of mounts (e.g., MB 200 UMH) and the TMA tilt accessory. It allows the cabinet to be vertically rotated up to 45° in precise 5° increments , achieving finer aiming towards the audience in fixed wall or ceiling installations. It is supplied in a black finish for discreet integration with most Electro-Voice enclosures and hardware.
