HIGH DEFINITION DISTRIBUTED SYSTEM™ BRC1™

The BRC1 offers control for small classrooms or other single zone applications. The BRC1 includes VCA control, 1/8 inch audio front panel input for iPOD or computer audio connection, externally controlled pull to ground Mute and external remote level control.

Ships with UL listed external power adaptor capable of up to 40 watts total speaker output power. Optional higher power AC adaptor is available for higher wattage speaker power. The BRC1 makes single zone installations easy and offers exceptional performance in a small package.

Description
The HDDS BRC1 allows connection of a stereo source via the rear panel Left / Right RCA input connector. A second input on the front panel allows connection for any external 1/8 inch RTS jack for connection to an IPOD, mp3 player or Computer Audio connections. When a jack is plugged into the 1/8 connector on the front panel it will defeat any audio connected to the rear stereo RCA connectors on the back panel. Power from the included external 18VAC adaptor is internally converted to +/- 22VDC and fed to the output RJ45 connectors providing the Left and Right outputs. When power is applied to the BRC1, the front panel power LED will illuminate. Cat5 cable is used to connect the BRC1 Left and Right RJ45 outputs to any of the HDDS series speakers.

The BRC1 allows connection via the Remote Level port on the front panel to an external Remote Level Control, HDDS RM10. The Remote Level Control is a 10-volt DC control connected over a Cat5 cable to a simple potentiometer that adjusts a DC voltage fed back to the internal Voltage Controlled Amplifiers (VCA). This means that no audio is fed down the cable and a single DC voltage is used to simultaneously adjust both the Left and Right output levels. The rear panel also includes a Phoenix style connector providing a MUTE function. The connector provides a ground connection at Pin 1 and a MUTE trigger signal at pin 3. When the trigger line (pin 3) is pulled to ground the BRC1 will mute both the Left and Right outputs.

The power adaptor supplied with the BRC1 is capable of driving two to four speakers with a total of 40 watts. If more power is required for a specific application a high-output 18-volt power adaptor is available from ISP Technologies, which can provide higher output current, thus providing more power per speaker.
