The iOne has one instrument input and one microphone input. It's perfect for a singer/songwriter who plays guitar or bass.

Excellent choices for mobile musicians, sound designers, and podcasters, the USB 2.0 bus-powered AudioBox iOne and iTwo provide high-quality audio I/O for Mac®, PC, and Apple iPad®. These compact, ruggedly built interfaces offer high-performance Class A mic preamplifiers, record 24-bit audio at up to 96 kHz, and include powerful, easy-to-use Studio One® Artist DAW for Mac and Windows and Capture™ Duo recording software for iPad.

PreSonus is famous for its tightly integrated hardware/software solutions, and the AudioBox i series is no exception. Of course you get Studio One Artist. But we didn't stop there!

PreSonus' award-winning analog signal processors and microphone preamps have long been popular among top professionals and home enthusiasts alike. So when you see the name PreSonus, you expect top audio quality—and the AudioBox i series delivers.

AudioBox iOne and iTwo are mobile interfaces in the best sense of the term. They can sit on a tabletop or fit in the pocket of a backpack or laptop bag and are powered by the USB bus, so you don't have to mess with a "wall wart" power supply or AC cord. And they're built to withstand the rigors of travel.

The AudioBox i series consists of two great 24-bit, 96 kHz mobile-recording solutions: the compact AudioBox iTwo and subcompact AudioBox iOne.
