MOTU is now shipping the UltraLite-mk4 ($595), a half-rackspace, 18-input, 22-output audio interface with best-in-class analog audio quality, DSP mixing, new optimized low-latency drivers and wireless control for mobile audio recording and mixing. The UltraLite-mk4 connects to a computer through high-speed USB 2 (audio class compliant, compatible with USB 3 and iOS) and records at sample rates up to 192 kHz.
The latest in MOTU's award-winning UltraLite series, the UltraLite-mk4 provides a total of 40 simultaneous I/O channels, including two front-panel XLR/TRS combo-style mic/guitar inputs with preamps, 6x10 balanced ¼-inch analog I/O, 8-channel ADAT optical (switchable to stereo TOSLink), stereo RCA S/PDIF I/O and MIDI in/out jacks, all housed in a compact, rugged aluminum alloy chassis that slides easily into a backpack.
The balanced, DC-coupled analog outputs achieve a measured dynamic range of 117 dB.
New, optimized drivers for Mac and Windows deliver ultra-low latency performance, with roundtrip latency (RTL) as low as 1.83 ms (with a 32-sample host buffer setting, operating at 96 kHz).
Expanded DSP doubles the available processing power (from the mk3) for the redesigned console-style mixer, which provides 48 inputs, 12 stereo busses and 32-bit floating point effects processing, including modeled analog EQ, vintage compression and classic reverb. Matrix routing lets users quickly patch ins to outs, or split inputs to multiple destinations. Users can take the UltraLite-mk4 on the go as a mobile mixer, controlling everything wirelessly from innovative web app software running on an iPad, iPhone, tablet, smartphone and laptop.
Like all MOTU audio interfaces, the UltraLite-mk4 includes a suite of audio analysis tools, including a full-screen real-time FFT display, spectrogram “waterfall” display, full-featured oscilloscope, X-Y plot and phase analyzer.
