Griffin Technology has released its 4-port USB-Audio hub, which was designed for compatibility with USB audio recording and playback. The hub can function un-powered or through an included AC power adapter. In addition, Griffin has released its ClearChoice iPod Connection Kit, which includes a 7-inch mini-jack male to RCA Female adaptor and a 6-foot mini-jack to male RCA cable — everything needed to connect the iPod to a home stereo system. The USB-Audio Hub sells for US$39, while the ClearChoice iPod Connection Kit costs $14.99. (Griffin’s site had yet to be updated with the new products at press time.)
