MOTU UltraLite-mk4 USB Audio Interface

The MOTU UltraLite-mk4 provides flexible and mobile USB2 audio connectivity to your computer with ultra-low latency and superb analog quality at sample rates up to 192 kHz. You get all the I/O you need, including two mic/guitar inputs, six line-level analog inputs, ten analog outputs, 8-channel optical digital I/O, S/PDIF digital I/O, MIDI I/O and a headphone output.

Built for Studio and Stage

Housed in a compact, aluminum alloy enclosure you can take anywhere, the UltraLite-mk4 is equally well-suited for studio and stage, with or without a computer. As an interface or standalone mixer, the UltraLite-mk4 provides 18 inputs and 22 outputs, for a total of 40 I/O channels.

All the I/O You Need

Connect all of your audio gear, including speakers, headphones, mics, guitars, synths, keyboards, drum machines, effects processors and even MIDI devices.

Large Console-Style Mixing

Record, monitor, route and process all live inputs using the on-board 48-channel large console-style mixer, with no latency and no processor strain on your computer.

DSP-driven Effects Processing

Apply hardware-based, DSP-driven effects processing to your mix, independent of your host computer. Add Classic Reverb with lengths up to 60 seconds.

Modeled Analog EQ and Compression

Further sculpt your sound with 4-band parametric EQ featuring filter types carefully modeled after British analog console EQs. Choose between two forms of compression: a conventional compressor and the Leveler(TM), an accurate model of the legendary LA-2A(TM) optical compressor that provides vintage, musical automatic gain control.

Advanced Extras

Analyze and scope your audio with advanced diagnostic tools, including a full-screen real-time FFT display, spectrogram "waterfall" display, full-featured oscilloscope, X-Y plot and phase analyzer.

Mobile Recording and Mixing

After recording and mixing in the studio, take the UltraLite-mk4 on the road with your laptop for mobile recording and live mixing.

From studio to stage, the UltraLite-mk4 delivers exceptional sound quality, ultra-low latency drivers, state-of-the-art operation and rock-solid performance.

1. zZounds offers the industry‘s most musician-friendly payment plans

zZounds offers a variety of Play as You Pay installment plans that allow you to get the gear you want today. While our competitors might offer house credit cards that require you to fill out an application and pass a credit check, our payment plans are easy to get, simple to use, and, best of all, accrue zero interest. Unlike those house credit cards that can leave you vulnerable to exorbitant interest charges once the promotional period ends, we never have and never will charge interest when you take advantage of one of the zZounds Play as You Pay plans.
