Whether you’re recording in the studio, taking direct output feeds off of an analog mixer, or using it live onstage, the MOTU Ultralite AVB gives you the flexibility and low latency you need. Like the rest of MOTU’s popular AVB-equipped audio interfaces, the Ultralite AVB lets you send and receive analog and digital audio across a standard network. The internal mixer also includes all kinds of DSP processing, summing, and routing options too, and between its high-speed USB 2.0 connectivity and additional optical I/O, you can easily expand the capabilities of your MOTU Ultralite AVB.

Audio Quality
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 demanding situations
New for 2019, the UltraLite AVB now includes renowned ESS Sabre32™ DAC technology, delivering 123dB dynamic range and the same proven, award-winning audio quality as MOTU’s flagship 1248. Renowned drivers deliver rock-solid performance and industry-leading low latency.

Universal connectivity
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.


DSP-powered mixing
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 sat is now yours.

Modeled analog EQ and compression
Vintage processing with 32-bit float precision
British analog mixing consoles are renowned for their musical EQ profiles. The UltraLite AVB meticulously models these classic EQs to give you the very same, magical EQ response found on these coveted desks. Each input channel also provides a classic compressor with peak/RMS operation.
Groups and the Main Mix bus are equipped with MOTU’s Leveler™, an accurate model of the legendary Teletronix™ LA-2A™ optical leveling amplifier, known for its highly sought-after Automatic Gain Control (AGC) characteristics.

Web app control from any device

Use any web client on any platform – Mac, Windows, Linux, iOS, Android – as long as it shares the same network.
