MOTU UltraLite-mk4 - 18x22 USB Audio Interface with DSP

The latest in MOTU's award-winning UltraLite series, the UltraLite-mk4 is a USB audio interface with 40 simultaneous I/O channels (18 in, 22 out). It also delivers exceptional sound quality, new ultra-low latency drivers and expanded DSP for studio-grade mobile audio recording.

Superb audio quality

Analog outputs deliver 117dB dynamic range at sample rates up to 192 kHz. Renowned drivers deliver rock-solid performance and industry-leading low latency.

Ultra-low latency

New, optimized drivers for both Mac and PC deliver ultra-low latency performance. With a high-performance DAW such as Digital Performer, the UltraLite-mk4 delivers an astonishing round trip latency (RTL) of 1.83 ms (milliseconds) on OS X and 1.84 ms on Windows over USB (at 96 kHz with a 32-sample host buffer).

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 mixer, the UltraLite-mk4 provides 18 ins and 22 outs, for a total of 40 simultaneous 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.

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™, an accurate model of the legendary LA-2A™ 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.

Web app control

The software that you use to control the UltraLite-mk4 doesn't reside on your hard drive. It's a web app served from the hardware itself. This means you can control the UltraLite-mk4's on-board DSP, mixing, and device settings from the web app software running in your favorite web browser on the computer, or even a tablet or smartphone on the same Wi-Fi network as your computer.

Solid Metal Chassis

The UltraLite-mk4 aluminum chassis is lightweight, yet incredibly sturdy and durable, and designed to withstand the rigors of the studio, stage, and tour bus. In a world awash with cheap plastic, the cool touch of the UltraLite-mk4's metal exterior in your hands is a reassuring reminder that you are holding quality engineering and construction built to last.

Rack mounting brackets

Use included brackets and hex bolts to mount the UltraLite-mk4 on rack rails, as shown here with a companion MOTU micro lite MIDI interface. 

Use the included jointer bracket to connect another MOTU half-rack interface (MIDI or audio). You can then mount them together in a standard 19-inch equipment rack.
