Handy Interface Connects Via USB or AVB

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.

MOTU Ultralite AVB Audio Interface at a Glance:
  • Versatile I/O for the flexibility you need
  • Powerful built-in effects and routing
  • Imagine the possibilities with AVB expansion
Versatile I/O for the flexibility you need

Sweetwater and MOTU have had a wonderful and long relationship, largely because they manage to deliver such exceptionally high-quality sound with every product they make, offering our customers superb sound at remarkably affordable prices. The Ultralite AVB follows this legacy without fail, packing plenty of great-sounding inputs and outputs into a fantastically affordable mobile unit. This includes a 10-in/6-out analog I/O with two stellar microphone preamps, two HiZ guitar inputs, and a 117dB dynamic range that stands up to some of the most impressive gear on the market. On top of that, the Ultralite AVB offers you digital inputs via optical I/O and MIDI in and out for your keyboard or other MIDI controllers.

Powerful built-in effects and routing

The onboard DSP mixer offers a number of advantages you'll find useful in a variety of settings, such as when you're connected via USB or using the Ultralite AVB in a standalone format. This digital mixer supports up to 48 inputs (via AVB expansion) and 12 stereo busses, allowing you to set up extremely complex routing schemes completely independent of your computer. In fact, if you connect a wireless router to your Ultralite AVB, you can access all of its internal mixing functions via an app on your iOS device or any device connected to your WiFi network, turning this powerful audio interface into a fully capable standalone mixer. Speaking of onboard processing and effects, whether you're in the studio or onstage with your Ultralite AVB, you'll find a ton of uses for its DSP EQ, compression, gate, and reverb including the built-in accurate model of the legendary LA-2A optical compressor which provides vintage, musical automatic gain control.

Imagine the possibilities with AVB expansion

Another extremely cool use of the Ultralite AVB's Ethernet connection is the ability to link more MOTU AVB equipped audio interfaces to it. You can do this in one of two ways: directly via a simple Ethernet cable or as part of an audio network via one or more MOTU AVB Switch. If you go with just a single Ethernet cable, you can easily link a second Ultralite AVB or other AVB ready device directly to your first one. With MOTU AVB Switches, you can create an audio network of up to five units, potentially linking hundreds of channels of I/O across multiple rooms. And since it's all over standard Cat-5e Ethernet cable, latency or cable runs aren't any kind of issue.

MOTU Ultralite AVB Audio Interface Features:
  • 18 x 18 audio interface with 36 simultaneous audio channels
  • Analog I/O includes 2 mic inputs, 2 guitar inputs, 6 line inputs
  • 8 line outs including dedicated main left and right outputs
  • Convenient front panel headphone output with its own volume knob
  • Optical I/O gives you 8 channels of digital input and output
  • 48-channel DSP-fueled onboard mixer gives you the added benefit of EQ, compression, and effects
  • Web app control from any device with CueMix
  • Onboard effects processing gives you vintage-modeled reverb, an LA-2A compressor, and British analog console EQs
  • Flexible matrix routing and splitting lets you send any input to any output
  • Mixer lets you control routing to and from your computer plus other networked AVB devices
  • Compatible with iPad/iOS (w/ Camera Connection Kit) and other USB 2.0 audio class-compliant hosts
  • Includes AudioDesk recording software for Mac and Windows

Excellent product over 13+ years

I bought the original 1st-gen (firewire!) Ultralite back in 2007, and after many years of studio use finally upgraded to this version in 2020 -- which looks to be the 5th(?) generation! It's just as awesome as the original -- tons of inputs and outputs, high quality XLR and mic preamps, and excellent ADC/DAC quality. It "just works" on my Mac. Of course this latest generation is amazing, because it contains a mixing board entirely implemented within internal software/hardware. The device has an onboard web-server that shows you a web page that basically looks like a classic Mackie Board, where you can mix every input and output, and even includes on-board EQ, compression, and reverb. This all happens *without* using a DAW -- so you can process and mix and directly monitor everything with anything that has a web browser (laptop, tablet, or phone.) Really impressive.

My only complaint is that setting up the "internal routing" of which inputs get sent to which outputs can be extremely confusing. Your best bet is to just use a 'default' config. After some delicate tweaking, I really found myself wishing I could save custom routing/mixing configurations to disk somehow, but that feature seems to be missing. :-(

Very Impressed

This hits the nail on the head and is exactly what I needed. It has plenty of I/O along with DC coupled outputs to connect my modular synthesizers to CV Tools on Ableton Live. Pair that with a very solid build quality, and fairly stable drivers (a little buggy at first but you quickly work the kinks out of your system adjusting preferences after a few days) and I was sold.

The ESS Sabre32 converters in the 2019 update are amazing. Aggressively transparent, and they show all the details I was missing before. Honestly, and surprisingly, I prefer this interface to an Universal Audio Apollo I formerly had. Very impressed, especially for the price. Great experience ordering from Sweetwater, as always.

Sorry I waited so long......

I had put off trying a MOTU product for many years, to be disappointed that I hadn't made the move sooner! The features and quality compare to many higher end units in this category. Also with the "stand-alone" mixer control feature saves me from bring an additional mixer out to a gig to mix additional gear. I am currently using the Ultralite as a companion unit for my "road" rig. The interface is perfect and doesnt add any additional latency when running a boat load of Vst's live. With my custom 1U 3.4Ghz 8 core pc running a plug-in host, iv'e been able to run 11 instance combinations of Keyscape, Ominsphere and Kontack with a 256 sample bus size with 40% cpu load!!

Motu AVB USB

Product works as advertised - fantastic. Great and timely delivery from Sweetwater. Very pleasant experience. Will order again.

UltraLite AVB - A solid little interface

The UltraLite AVB meets my needs for an audio interface with lots of 1/4 connections. Both the USB and AVB (Ethernet) connections work. Keep in mind that you'll need an external AVB router if you want to use Ethernet both for local use as an AVB interface and network use via the iphone app.

I've been using it for a few weeks -- I'll update the review after I've used it for 6 months.

While this unit is awesome for what it is, consider the MOTU 1248, which adds a Thunderbolt interface, among other features. As a Mac use this would be awesome. However, I've been able to get some screaming AVB/Ethernet throughput, so I'm set with the UltraLite.

Great service and support from Sweetwater, as always.
