The Bose ControlSpace CC-64 control center is an elegant, programmable, networked controller that provides users a simple and logical interface to their sound systems when using ControlSpace ESP processors and/or network version PowerMatch® amplifiers. Because the controller is completely programmable, you can customize the sound system, making only certain controls available, and simplifying user interaction with the system. The CC-64 provides four rotary encoders with circular LED rings for a user-friendly method of managing gain settings or scene selections. A fifth encoder (upper right) provides control over programmed “scenes” or presets. Four bank switch buttons redefine the four Gain/Selector control knobs, providing quick access for up to 16 system gain controls or selectors. A large, two-line-by-40-character backlit LCD provides users the names of the system elements they are controlling.
