Presonus New iSeries
Presonus recently released their two new mobile interfaces , the stella upgrade from the AUDIOBOX USB interface up to theAUDIOBOX iSeries featuring to new models under this range the iONE & iTWO
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. With the both interfaces Presonus has thrown in their flagship DAW Studio One Artist and for those operating on the move , Presonus has made things simpler by integrating their free Capture™ Duo two-track recording software for iPad. Based on PreSonus’ Capture live-recording software for StudioLive mixers, Capture Duo lets you record two stereo tracks using the AudioBox iOne or iTwo or any other iPad interface that supports Core Audio for iPad, including the iPad’s built-in mic. Once recorded you are able to wirelessly send your recording into the Studio One DAW. Upgrade the Capture Duo to Capture via the Apple app store and you can extend your recording environment to a 32 track recording device .
PreSonus’ award-winning analog signal processors and microphone preamps have long been popular among top professionals and home enthusiasts alike. So its no surprise that they have not limited themselves to include this in the iSeries .The AudioBox iOne and iTwo deliver excellent audio performance, thanks to their newest, sweet-sounding Class A mic preamplifier and professional-quality, 24-bit converters that sample at up to 96 kHz.
Whats CLASS A you might ask , power amplifiers are classified primarily by the design of the output stage and are designated Class A, B, AB, D, G, or H. In a Class A preamp, the output circuits are always on for the entire cycle of signal swing or the bias current flows at all times.
As a result, Class A preamps that use quality components, such as those in the AudioBox iOne and iTwo, have the most linear design, with the least amount of crossover distortion, and they deliver purer, clearer, and more musical results than the Class AB designs that are found in many preamps.
Not only do they look good but they are built rugged,designed to excel as mobile interfaces, they built them to take a serious pounding and remain completely reliable. They’re built like small tanks, with a metal chassis and knobs/jacks secured directly to the enclosure to reduce strain on the internal circuit board.

So whats the difference you might ask in models, both the AudioBox iOne and iTwo offer the features, high-end audio quality, and legendary PreSonus software integration that makes the i series special. Both are two-in, two-out audio interfaces with left and right balanced ¼” audio outputs and one headphone out, So whats the difference you might ask :
The iOne has one instrument input and one microphone input. It’s perfect for a singer/songwriter who plays guitar or bass. The iTwo has two combo mic/instrument/line inputs, so it’s the way to go for recording in stereo with mics or a keyboard and for capturing duets, such as two guitars, two singers, or guitar and bass.
The iTwo has MIDI I/O; the iOne does not.
The iTwo also has a Mix knob that blends the live inputs with the return streams from the computer for zero-latency monitoring; the iOne has a fixed 50/50 low-latency monitoring blend using the Direct button.
Finally, the iTwo is compact and lightweight but the iOne is even smaller and lighter—a subcompact, if you will.
Otherwise, the features, capabilities, audio quality, construction quality, and included software of the two units are identical.
On our opinion the iseries is a slight extension from its predecessor the AUDIOBOX USB, still giving the great value of a high end interface with the affordability of a budget interface.
