"Make the Audio Express the centerpiece of your personal studio! This 6-in/6-out audio interface puts the right connectivity where you need it: on your desktop. It's perfect for the singer/songwriter first starting to record, yet the Audio Express offers premium sound quality (better than CD, at 24-bit/96kHz) so it's perfect for the top-level engineer who needs a mobile recording solution. Better yet, the MOTU Audio Express features both USB and FireWire ports. That means it'll work with nearly any computer you'll come across, so it's easier than ever to collaborate. Just put the MOTU Audio Express in your laptop bag, bring it to your bandmate's house, and you can get going."
