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 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.
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 seat 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
Control everything from your laptop, tablet and smartphone
The software that you use to control the UltraLite doesn't reside on your hard drive. It's a web app served from the hardware itself. This means you can control the UltraLite's on-board DSP, mixing, device settings, and network audio routing from the web app software running in your favorite web browser on a laptop, tablet or smartphone connected by wire or Wi-Fi to your local area network. Use any web client on any platform — Mac, Windows, Linux, iOS, Android — as long as it shares the same network.
Stand-alone mixing with wireless control
Control everything from your iPad or iPhone
Connect an Apple Airport™ or other Wi-Fi router directly to the UltraLite with a standard Ethernet cable and control the UltraLite AVB's powerful mixing and DSP effects from your smartphone or tablet, without a computer. Great for live sound mixing!
Comprehensive metering
View all I/O activity at a glance
The large backlit 128 x 48 pixel LCD lets you view all signal activity at a glance with detailed metering for all analog and digital I/O. Access hardware settings from a simple and convenient menu.
Quick Setup presets
Completely transform your MOTU interface with one click
The UltraLite AVB is so flexible, it can serve many roles — in the studio, on stage, and throughout an installation. The Quick Setup menu lets you instantly reconfigure the UltraLite AVB for many common situations, from operation as a standard audio interface to serving as a network "snake" from one location to another. Once a preset is chosen, you can easily customize the routing grid and mixer settings to further suit your specific needs — and then save your own custom presets.
