The AudioBox iOne includes one instrument input and one mic input, while AudioBox iTwo offers two combo mic and switchable line/instrument inputs. Both feature Class A mic preamplifiers with phantom power and 24-bit, up to 96 kHz converters with 105 dB of dynamic range. The DACs feed balanced ¼-inch, line-level outputs and a clear headphone output with independent level control. The AudioBox iTwo also includes MIDI In and Out. Each interface has an internal analog mixer with zero-latency monitoring, enabling you to monitor recorded tracks and overdubs without audible delay.
Small, lightweight and USB bus-powered, the AudioBox iOne and iTwo can sit on a tabletop or fit in the pocket of a backpack or laptop bag. They’re built to travel, with a metal chassis and knobs and jacks secured directly to the enclosure to reduce strain on the internal circuit board.
Both interfaces work with any recording software that supports Core Audio (Mac) or ASIO (Windows) and here are all the detailed specs.
