The Bose link AR1 wireless audio receiver works with the AL8 wireless transmitter connected to your Lifestyle DVD system. If you've already expanded your system benefits to a second room with the AL8 homewide wireless audio link—consisting of a transmitter and receiver—this individual AR1 receiver will establish sound in yet another listening area. The AR1 receiver accepts two independent audio streams from your Lifestyle system in this listening area. And there's no room-to-room wiring required between the two. Connect your receiver to a Bose link–enabled product and receive signals from up to 80' away. Radio-frequency operation allows reception through most walls and floors. You can also choose to receive audio from any components connected to your Lifestyle system.
