MOTU UltraLite AVB

The MOTU UltraLite AVB brings the most I/O ever offered in the UltraLite series — 18 inputs and 18 outputs (36 simultaneous channels) — to a compact, road-ready half-rack chassis. Updated with ESS Sabre32 DAC technology for 123 dB of dynamic range, it connects over class-compliant USB 2.0 or AVB Ethernet at sample rates up to 192 kHz.

Analog I/O includes 2 mic inputs, 2 hi-Z guitar inputs and 6 line inputs, plus 8 line outputs, a headphone output and 8-channel optical I/O (with stereo TOSLink S/PDIF). MIDI I/O and a large 128 × 48 backlit LCD for full metering round out a feature set that punches well above its size.

A 48-channel console-style mixer — identical to the one in MOTU's flagship 1248 and 16A — adds 12 busses with modeled British EQ, classic reverb and LA-2A-style leveling, all controllable wirelessly via the MOTU web app. Connect a Wi-Fi router for cable-free control, daisy-chain other MOTU AVB interfaces over Ethernet, or run the UltraLite AVB standalone as a mixer on stage.

Introducing the UltraLite AVB - 18 x 18 USB / AVB audio interface with DSP mixing, wi-fi control and audio networking
The latest in MOTU's popular, award-winning UltraLite interface series, the UltraLite AVB is an 18-input, 18-output audio interface with DSP mixing, wi-fi control, AVB audio networking and best-in-class analog audio quality for on-the-go mobile audio recording.

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 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 from any device - Control everything from your laptop, tablet and smartphone
The software that you use to control the UltraLite AVB doesn't reside on your hard drive. It's a web app served from the hardware itself. This means you can control the UltraLite AVB on-board DSP, mixing, device settings, and network audio routing from 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.

Touch Console - The art of the mix on your touchscreen
Designed specifically for touchscreen operation, Touch Console™ delivers a whole new mixing experience. Access Touch Console from your tablet or smartphone to effortlessly control the powerful 48-channel mixer and effects in the UltraLite AVB. With large targets for your fingers, multi-touch operation and intuitive design, you can tap, swipe and pinch your way to a perfect mix, every time.

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!

System expansion and audio networking - Expand your system with more I/O and Wi-Fi control
The UltraLite AVB network port introduces AVB Ethernet, the new industry standard developed by the IEEE for professional audio networking. Add a second MOTU AVB interface (1248, 8M or 16A) with a simple Cat-5e or CAT-6 ethernet cable.

Connect up to five MOTU interfaces using a MOTU AVB Switch (sold separately).
Build a network with multiple interfaces, computers, and AVB switches using standard network cabling, with ultra-low network latency, even over long cable runs (100 meters point to point). Stream hundreds of audio channels among devices and computers on the network.

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.
