The Bose link AL8 homewide wireless audio link is the easiest way to expand your Lifestyle® system to additional rooms. This transmitter and receiver package delivers two independent audio streams from your system to Bose link–enabled products in another room. All without running room-to-room wires. Wherever you listen, you’ll have the benefits of the Lifestyle® system with you. One connection from the transmitter to your Lifestyle® system media center sets the foundation for a house full of sound. All that’s left is to connect the receiver to a second-room speaker system. You’ll also receive audio from any components connected to your Lifestyle® system. The key technology for this homewide wireless audio solution is our proprietary Free Field® circuitry. It enables the Bose link AL8 transmitter to operate efficiently in the presence of signals from cordless phones, wireless Internet connections and other devices. And it helps deliver Bose quality sound throughout your home, without interruption, and with low transmission latency. This virtually eliminates the echo effect heard when a wireless signal plays back much later than the original. The transmitter and receiver work through most walls and floors, and operate from up to 80′ away. Individual AR1 receivers (purchased separately) can be placed in seven additional rooms for wireless audio transmission from a single AL8 transmitter.
