18x22 USB Audio Interface with DSP, Mixing and Effects
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
UltraLite-mk4 includes renowned ESS Sabre32™ DAC technology, delivering 123dB dynamic range and the same proven, award-winning audio quality as MOTU's flagship 1248. 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.
Large console-style mixing
Record, monitor, route and process all live inputs using the on-board 48-channel, console-style mixer, with no latency and no processor strain on your computer.
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.
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.
Web app control from any device
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 on-board DSP, mixing, device settings, and network audio routing from your favorite web browser on a laptop, tablet or smartphone connected by wire or Wi-Fi to your local area network. Use any web client on any platform - Mac, Windows, Linux, iOS, Android - as long as it shares the same network.
Touch Console
Designed specifically for touchscreen operation, Touch Console™ delivers a whole new mixing experience. Access Touch Console from your tablet or smartphone to effortlessly control the powerful 48-channel mixer and effects in the UltraLite-mk4. With large targets for your fingers, multi-touch operation and intuitive design, you can tap, swipe and pinch your way to a perfect mix, every time.
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.
