This white Bose Professional ControlSpace CC-16 Zone Controller is a wall-mounted device designed to provide an end-user interface for ControlSpace systems. Custom programming allows the CC-16 to control a variety of system elements, from switching remote audio sources to selecting "scenes" or system configurations, allowing multiple room usage scenarios to be recalled from the CC-16 by end users. The controller fits into a standard 2-gang electrical wall box. Sealed VOLUME +/- and SELECT +/- pushbuttons help to keep dust and dirt out of the unit, and programmable software lock out keep unauthorized users from messing around with the settings.
