This is the wireless iPod speaker system that plays up to 100' from your iPod using an advanced 2.4 Ghz wireless signal to clearly broadcast music from the iPod charging base to the powerful integrated three-speaker unit. Compatible with any docking iPod, the base houses and charges your iPod while the compact speaker unit acts as a remote control for the iPod, with a compact LCD showing volume, bass and treble controls, play/pause status, and battery level. The system connects to your Mac or PC to update your iPod using iTunes, while Video- and Audio-Out ports allow you to play your music or video through an external stereo or home theater system. A single stereo line-in enables you to connect an external audio source such as a portable CD or satellite radio player. The speaker unit recharges via AC and provides up to eight hours of use per charge. 7 1/2" H x 8" Diam. (4 lbs.)
