Compact 18x22 USB2 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. Analog outputs deliver 117dB dynamic range at sample rates up to 192 kHz. Renowned drivers deliver rock-solid performance and industry-leading 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). 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. Connect all of your audio gear, including speakers, headphones, mics, guitars, synths, keyboards, drum machines, effects processors and even MIDI devices. 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. 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. 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. After recording and mixing in the studio, take the UltraLite-mk4 on the road with your laptop for mobile recording and live mixing.
