Overview Thunderbolt technology Thunderbolt fulfills the promise of a truly state-of-the-art connectivity standard for personal computers. With massive bandwidth, Thunderbolt allows you to connect displays, hard drives, and other peripherals to your computer, along with the 828x, up to six devices total (with the 828x at the end of the chain), and the Thunderbolt bus won't even break a sweat. Hi-speed USB 2.0 Mac, PC, and USB 3.0 compatible As Thunderbolt becomes more widely adopted, Hi-speed USB 2.0 provides across-the-board compatibility with virtually all laptops and desktops on both Mac and Windows. Since USB 2.0 devices are compatible with USB 3.0-equipped hosts, your 828x interface is a future-proof investment in your studio. 28 inputs and 30 outputs How can one audio interface offer this much I/O? Pack it in, like no one else can: two combo-style mic/guitar inputs with preamps, 8 balanced analog in/out, XLR main outs, 16 channels of ADAT optical (8 channels at 96 kHz), plus S/PDIF, word clock and MIDI. Connect all of your studio gear, including microphones, guitars, synths, keyboards, drum machines and even effects processors. Recording up to 192 kHz Audio quality without compromise Now in its fifth generation, the 828 has become a benchmark for the industry, setting the bar by which others are judged. How has this level of respect been earned? Through consistent design integrity and intelligent use of current-generation parts and design technologies. Solid metal chassis MOTU interfaces are built to last, and last, and last… We still get calls and Facebook posts from happy users of the original 828, introduced more than 10 years ago! Like all MOTU interfaces, the 828x's aluminum alloy chassis is lightweight, yet incredibly sturdy and durable, and designed to withstand the rigors of the studio, stage, and road. In a world awash with cheap plastic, the cool feeling of the 828x's metal exterior in your hands is a reassuring reminder that you are holding quality engineering and construction. Support for Mac OS X and Windows Run all your favorite audio apps The 828x provides time-tested drivers for Mac OS X and Windows (8, 7 and Vista) for cross-platform compatibility with virtually all audio software via WDM, ASIO, and Core Audio drivers. The 828x's unique V-Limit™ hardware limiter employs a proprietary design to offer an additional 12 dB of headroom over digital zero with no digital clipping or harsh artifacts, for that added protection in dynamic recording situations. The 828x's preamps are clean and neutral, allowing you to use your favorite plug-ins and host software to color the sound just the way you want for each recording application.
