The Cambridge Qt Room Control Volume Control can be used to adjust the sound masking level for an individual room or a space with 2-8 emitters. This wall mounted volume control unit is designed to work with any of the Cambridge Sound Management sound masking systems. It installs easily in new or existing construction and fits in most standard electrical boxes, including open back, low voltage brackets. Since the QtRC is designed for a room of up to 8 emitters, a separate zone should be used in larger areas. The QtRC controlled room can be its own run from the controller or part of a run to other areas. For more information, refer to the Qt Room Control Installation and Operations Guide.
