With Belkin G3A2000 Using your phone's Bluetooth® connection, the HD Bluetooth Music Receiver lets you play your smartphone's audio through your stereo system or stand-alone speakers. You'll be able to browse your playlist and change music tracks from up to thirty feet away. The receiver stores settings for connecting to up to eight devices--ideal for large households. Simply tap your device (NFC phones with Android OS 4.1 or higher) to the receiver for instant wireless pairing. If you have a smartphone with Android 4.0 or 4.0.1, you can download the free Belkin BT app to get the tap-and-play feature. The receiver offers two HD audio outputs: a digital coaxial audio out and a digital optical audio out. A traditional 3.5-millimeter-to-RCA connection accommodates older home theater setups.
