Use this compact adapter with your Paradigm A2 powered speakers, or any sound system with a minijack input, for convenient wireless audio playback with Bluetooth-enabled devices. Listen to music from your laptop or tablet computer on your home audio system while you surf the web, or enjoy your favorite MP3 tunes from your Bluetooth-enabled cell phone. You won't need to physically connect either device to your speakers, thanks to the BD1's 33-foot wireless range. The BD1 can be powered up by plugging the included AC adapter into the A2 speaker's back-panel convenience outlet for a clean, hideaway setup. A built-in rechargeable battery even allows it to operate if there's no AC outlet handy.
