36 simultaneous audio channels
The most I/O ever offered in the UltraLite series
You get 2 mic inputs, 2 guitar inputs, 6 line inputs, 8 line outputs, headphone out and 8-channel optical I/O for a total of 18 inputs and 18 outputs, simultaneously. The optical ports also support stereo TOSLink (optical S/PDIF).
Best-in-class analog audio quality
Performance suitable for the most
The UltraLite AVB sets a new standard for analog audio performance in a mobile audio interface. The eight balanced analog outputs deliver a stunning 117 dB dynamic range. This level of measured performance had previously only been available in audio interfaces that cost thousands of dollars.
Class compliant USB 2.0 plus audio over Ethernet
The UltraLite AVB connects to your computer with audio class compliant hi-speed USB 2.0 (compatible with USB 3.0 and iOS) for across-the-board compatibility now and in the future. Alternately, if you have a Mac running OS X Yosemite (10.10) or later, you can use a standard Ethernet cable for operation as an audio interface. Either way, the UltraLite AVB is compatible with all audio software.
Console-style mixing with 48 channels and 12 busses
The mixer in the UltraLite AVB is a complete departure from earlier models. In fact, it's identical to the mixer found in MOTU's flagship 1248 and 16A interfaces. If you know your way around a large-format mixing console, you'll feel right at home. If you've ever wished to mix on a large console, the driver's seat is now yours.
