Introducing the UltraLite-mk4

Just when you thought it couldn't get any better, MOTU's award-winning UltraLite audio interface lineup has a new family member: the all-new UltraLite-mk4, with 18 inputs and 22 outputs for a total of 40 simultaneous I/O channels. With exceptional analog audio quality, DSP mixing, wireless control and new optimized low-latency drivers, the UltraLite-mk4 is sure to become another MOTU classic.


Tons of I/O in a compact form factor

As the very latest model in the series, the UltraLite-mk4 provides comprehensive I/O, including two front-panel XLR/TRS combo-style mic/guitar inputs with preamps, 6 x 10 balanced quarter-inch analog I/O, 8-channel ADAT optical (switchable to stereo TOSLink), stereo RCA S/PDIF I/O and MIDI in/out jacks, all housed in a compact, rugged aluminum alloy chassis that slides easily into a backpack.


Exceptional audio quality and new, optimized drivers

The balanced, DC-coupled analog outputs achieve a measured dynamic range of 117 dB, rivaling the audio quality of interfaces at much higher price points. New, optimized drivers for Mac and Windows deliver ultra-low latency performance, with roundtrip latency (RTL) as low as 1.83 ms (with a 32-sample host buffer setting, operating at 96 kHz).

DSP, mixing and mobile control

Expanded DSP doubles the available processing power (from the mk3) for the redesigned console-style mixer, which provides 48 inputs, 12 stereo busses and 32-bit floating point effects processing, including modeled analog EQ, vintage compression and classic reverb. Matrix routing lets you quickly patch ins to outs, or split inputs to multiple destinations. You can even take the UltraLite-mk4 on the go as a mobile mixer, controlling everything wirelessly from innovative web app software running on your iPad™, iPhone™, tablet, smartphone and laptop.

Computer/iOS connectivity and extras

The UltraLite-mk4 connects to a computer through hi-speed USB 2.0 (compatible with USB 3.0) and records at sample rates up to 192 kHz. It is also USB audio class compliant, so you can connect it directly to an iPad using a standard camera connection kit (adapter) for multi-channel I/O with your favorite audio apps.

Like all MOTU audio interfaces, the UltraLite-mk4 includes a suite of audio analysis tools, including a full-screen real-time FFT display, spectrogram “waterfall” display, full-featured oscilloscope, X-Y plot and phase analyzer.

Three UltraLite models to choose from

The UltraLite-mk4 joins two other models in the series lineup: the UltraLite-mk3, with "hybrid" FireWire/USB connectivity, and the UltraLite AVB, with it's powerful AVB/TSN Ethernet audio networking features.
