Presonus - AudioBox iOne
Portable, High Fidelity, and Multiplatform
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.
Tightly Integrated Software—As You Expect from PreSonus!
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!
Class A All the Way
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.
Heavy Metal Never Weighed So Little!
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.
Two to Go, Please!
The AudioBox i series consists of two great 24-bit, 96 kHz mobile-recording solutions: the compact AudioBox iTwo and subcompact AudioBox iOne.

The minimum system requirements may differ for DAWs other than Studio One. Please check the requirements for your DAW of choice with its manufacturer.
Note that the speed of your processor, amount of RAM and size and speed of your hard drive will greatly affect the overall performance of your recording system. Also, a more powerful system (faster processor with more RAM) will allow for lower latency (signal delay) than you might experience while monitoring audio or MIDI signals. Monitor resolution for both PC and Macintosh should be no lower than 1024x768 pixels.
