The PreSonus AudioBoxTM iOne ($129 MAP) and AudioBox iTwo ($159 MAP) are USB bus-powered audio/MIDI interfaces for Mac®, Windows® and Apple's iPad using an attendant USB power supply.
Both feature metal chassis and control knobs. The AudioBox iOne has separate XLR microphone input and 1⁄4-inch instrument jacks, while AudioBox iTwo offers two combo mic and switchable line/instrument inputs. Both feature high-performance class-A mic preamplifiers with phantom power, 24-bit/96 kHz converters, a pair of balanced 1⁄4-inch line outputs plus a separate headphone output jack and level control.
The AudioBox iTwo adds MIDI In/Out jacks and both interfaces have an internal analog mixer with zero-latency monitoring that works with any recording software that supports Core Audio (Mac) or ASIO (Windows). I tried my AudioBox iTwo with Pro Tools HD 11.2.1 running on my Mac and found it to be superior in all ways to the other small interface I had been using. These rugged PreSonus USB interfaces come with Studio One® Artist DAW software for Mac and Windows, and download links to new CaptureTM Duo recording software for iPad.
