The Zone Controllers offer extended utility to the DriveRackrand ZonePro families. The nine Zone Controllers use analog DC voltage to provide logic control ranging from zone source selection, volume and muting, to program or scene selection and fire safety muting. Wired with readily available and affordable CAT5 cable with universally accepted rj-45 connectors at distances up to 1000 ft, the ZC Zone Controllers offer simple yet elegant solutions to the contractor. The ZC-1 provides programmable remote volume control for the DriveRack 260, 220i and the ZonePro 640 and 641. The ZC-2 offers programmable volume and mute control for the DriveRack 220i, 260 and the ZonePro 640 and 641. The ZC-3 can function as a program selector for the DriveRack 260 and 220i; in addition it can be used for as a source selector, page steering control, or a scene selector for the ZonePro products.
