    MOTU 1248 Thunderbolt / AVB Ethernet / USB Audio Interface

    Notify me when this product is available:

    The 1248 is MOTU’s new flagship high-end audio interface that features flexible I/O configurations, very high quality analog performance and extremely low latency.  The 1248 also offers extensive 48-channel mixing, DSP effects, and high-performance AVB audio networking features. The MOTU 1248 Thunderbolt audio interface provides professional quality, industry-leading dynamic range and large console style mixing. With a total of 66 channels of audio I/O (32 ins and 34 outs), the 1248 also supports USB 2.0/3.0 connectivity which makes it extremely versatile.

      • MOTU 1248 FEATURES:

        The 1248 gives you everything you need to turn your computer into a powerful 24-bit/192 kHz digital audio workstation. As a “hybrid” audio interface, the 1248 provides flexible connectivity to your computer via ultra-fast Thunderbolt™ technology or high-speed USB2, with 30 channels of pristine analog I/O, combined with sixteen channels of ADAT optical digital I/O and stereo S/PDIF, for a total of 66 simultaneous audio channels. 

        The 1248 is equally well-suited for studio and stage, with or without a computer. As an interface or standalone mixer, the 1248 provides 32 separate inputs and 34 separate outputs, including four XLR mic inputs with individual preamps, two dedicated front-panel hi-Z guitar pickups, dedicated main outs and monitor outs, and two front panel headphone jacks. 

        Connect all of your studio gear, including microphones, guitars, synths, keyboards, drum machines and even effects processors. Record, monitor, route and process all of these live inputs using the professional on-board digital mixer – with no latency and no processor strain on your computer. Apply hardware DSP-driven effects processing to inputs, outputs, and busses independent of your host computer. Add Classic Reverb™ with lengths up to 60 seconds. Further sculpt your sound with 4-band parametric EQ 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. 

        Add more MOTU interfaces as your needs grow, connected to a state-of-the-art audio network using standard AVB Ethernet switches and CAT-5e cabling, with near-zero network latency, even over long cable runs (several hundred meters). Record and monitor up to 128 audio channels in and out, simultaneously, to a host computer through Thunderbolt. Route hundreds of audio channels among multiple devices and computers on the network. 

        Control all DSP-based mixing and effects, device settings, and network audio routing from web app software running in your favorite browser on your laptop, tablet or smart phone connected wirelessly or locally to the 1248 audio network. 

        From initial tracking to final mastering, the 1248 delivers superb sound quality, state-of-the-art operation, and reliable performance.
