Griffin Twenty Airplay Amplifier

Griffin’s Twenty product is a digital audio amplifier that uses Apple’s Airplay wireless audio/video protocol to connect your AirPort Express and your speakers. First you attach your digital device (whether a Airport Express wireless base station or any digital audio device) to Twenty using the supplied TOSLINK optical audio cable.  Next you connect your speakers to Twenty’s lugs.  Now, you’re ready to see the magic of Twenty.  With the zero-configuration audio set-up, you are able to stream by means of Apple’s AirPlay wireless protocol from your Apple device directly to your speakers via a low-profile digital amplifier.
