The DW3020 is a flush mount wall panel controller designed to work in combination with the R2 or M2 amplifier. It can be installed in a separate zone, and gives the possibility to select the desired audio source and adjust the volume for the zone that it’s applied to. The connection between the amplifier and the controller is made by using a standard 4-pin terminal block connector. The 45 x 45 mm size is compatible with AUDAC, Niko, Legrand and other standard 45 x 45 mm Mounting frames and cover plates.
