I'd be willing to bet that there's a few blind people who could come up with some wonderful uses for this product.
STEREO|iO is an interface box with a USB cable. One end has female RCA phono plugs for use with virtually any audio equipment from DJ mixers to turntables, and the other end has a USB connector. DJs can connect any line or phono-level gear to their Mac or PC via USB for recording, mixing or processing. DJs can also use STEREO|iO as an output cable from their computer to inputs on an analog mixer, enabling them to mix MP3s and other music from their computer in their traditional DJ mixer.
The STEREO|iO is touted to be a low-cost problem-solving tool which could prove to be invaluable for DJs and musicians who are holding gigs or are based
in the studio whenever there is a need for a connection. Since it runs on USB connectivity, it plays nice with both Mac and Windows machines without the
need for software-driver installation or external power for operation.
