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.

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.
