Griffin Twenty Amplifier Amplifies to the Max


Griffin launched the Twenty Audio Amplifier for Airport Express at CES 2012 today. This isn’t your dad’s amplifier. It’s small, sleek, and efficient. It is an audio amplifier that uses an Airport Express to capture the AirPlay stream, decode it, then send the lossless, amplified sound through speakers. It can do this from iTunes or any other AirPlay-enabled app such as Pandora or Spotify to the user’s speakers through a low-profile digital amplifier. It comes equipped with a power connection and mount for the Airport Express. The 2.1 channel sound system with 20 watts output per channel are nothing to scoff at, and it also supports a powered subwoofer with an automatic active crossover at 80 Hz.
