Presonus AudioBox USB audio interface

Presonus AudioBox USB

If you are a mobile musician or podcaster on a tight budget who relies mostly on software except for a couple of mics or instruments, and your computer is equipped with USB but not FireWire, we have just the recording interface for you: the AudioBox USB. This simple, handy little box connects to a computer via USB 1.1, so it works with virtually any PC or Mac, not just newer models. And it has just the right features for your basic recording needs—neither more nor less.
The AudioBox USB may be small and simple, but it boasts PreSonus quality inside and out. It offers excellent audio performance, thanks to two dual-purpose front-panel mic/instrument inputs with sweet-sounding Class A mic preamplifiers and professional-quality, 24-bit converters that sample at up to 48 kHz.
