Behringer has announced the easily remembered U-Control UCA202. It's basically a USB cord sticking out of a box that allows audio input and output from your Mac or "other". Seems neat and could solve some problems for some smaller editing setups I guess. I'd love to try one hint.
With this ultra-compact, bus-powered interface, you can link your Windows® and Mac® computer with any audio gear. There is no setup or special drivers needed—simply plug the interface in a free USB port on your computer and get into the groove.
The UCA202 provides 2 analog inputs and outputs, as well as an additional S/PDIF optical output for direct digital conversion. The stereo headphone output with dedicated level control lets you monitor both input and output. And the cherry on top is that the U-CONTROL download area offers a huge software package for recording and editing.
All in all, this interface is a complete audio solution which provides a connection between the analog and digital domain.
