Perfect for adding an audio system to either one large room or two smaller rooms, the Channel Vision A-BUS Audio Distribution Kit with Bluetooth & Speakers (2 Zones) gives you the ability to play audio through two individually controlled in-ceiling speaker pairs. You could, for example, install one pair in the kitchen and the other in the dining room, or one pair at the front end of the hall and the other pair at the back. The possibilities are many. The system receives audio from your Bluetooth-enabled or plug-in electronics and pumps out the sound through speakers in your ceiling. The two pairs of speakers are independently controlled, and you can easily adjust the volume of each pair through the included keypads. MAIN COMPONENTS (4) 6.5″ Builder Series In-Ceiling Speakers: Add quality sound to both zones at an excellent value. Each speaker features high power (120W) handling capability, a Polypropylene woofer with butyl rubber surround, a high compliance polymer tweeter, and a small perforated designer grille. Audio Distribution Module, 2-Zone: Plug an audio source (iPod, A/V receiver, CD player, etc.) into this distribution module in order to play audio from your device through the speakers. The system communicates via Cat5 wiring by sending the audio signal from this module to the amplified keypad and speakers. Bluetooth Local Input Module: This in-wall module enables Bluetooth audio streaming for the system. It wires into both the distribution module and the keypad. Once installed, you can pair the module with any Bluetooth audio device and stream music wirelessly to the speakers. (2) Amplified Keypads, 1 Source: The in-wall keypads provide convenient volume control and source selection.
