As a hybrid audio interface, the 828x connects to any Mac or PC using ultra-fast Thunderbolt technology or high-speed USB 2.0 and delivers DSP effects and mixing for all 28 inputs and 30 outputs with 32-bit floating point processing.
MOTU 828x Thunderbolt and USB Audio Interface Features
- Thunderbolt connectivity — Compatible with Thunderbolt 1 and 2.
- Hi-speed USB 2.0 connectivity — Compatible with USB 3.0.
- 58 simultaneous channels — 28 inputs and 30 outputs, including two mic preamps with sends, 8 TRS analog in/out, separate main outs on XLR jacks, two banks of optical, S/PDIF, MIDI in/out, time code in/out, word clock I/O, and two front-panel headphone jacks.
- CueMix FX — High-powered DSP with mixing and effects on individual ins/outs. Includes classic reverb, modeled analog EQ, and vintage LA-2A compressor.
- Flexible mic/guitar inputs with preamps — Two front panel combo jacks provide hi-Z 1/4” guitar input or XLR mic input with individual phantom power and pad.
- Precision Digital Trim — Digitally controlled analog trim
The 828x is equally well-suited for studio and stage, with or without a computer. As an interface or standalone mixer, the 828x provides two XLR/TRS combo mic/guitar inputs, 8 balanced TRS analog in/out, two banks of optical (ADAT and TOSLink formats), S/PDIF (coax) digital I/O, dedicated main outs on XLRs, and two front panel headphone jacks with independent volume control. The mic/guitar combo inputs are equipped with transparent preamps, digitally controlled trim with plenty of gain, a true high-impedance guitar input, individual 48V phantom power, -20 dB pad, and V-Limit, a hardware limiter that helps prevent digital clipping from overloaded input signals as high as +12 dB above zero with no clipping or harsh artifacts. Additional protection can be applied with Soft Clip.
All analog inputs are equipped with digitally controlled analog trim controls that allow adjustments in 1 dB increments. The mic/guitar input trims can be adjusted using front-panel digital rotary encoders that provide feedback in the front panel LCD, while all quarter-inch TRS inputs can be trimmed from the included cross-platform CueMix FX software. Different trim configurations can be saved as files on disk for instant recall.
Connect any 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 CueMix FX digital mixer – with no latency and no processor strain on the computer. Apply hardware DSP-driven effects processing to inputs, outputs, and busses independent of the host computer. Add Classic Reverb with lengths up to 60 seconds. Further sculpt your sound with 7-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 any mono or stereo audio stream with advanced diagnostic tools, including a full-screen real-time FFT display, spectrogram waterfall display, full-featured oscilloscope, X-Y plot, and linear/polar phase analysis graphs.
After programming the on-board mixing in the studio, unplug the 828x from the computer and take it on the road for operation as a stand-alone mixer with effects. All mixing and effects parameters are adjustable using the front panel backlit LCD.
Additional advanced features include 192 kHz operation, Direct Digital Synthesis (DDS) precision clocking, direct SMPTE time code sync (no extra synchronizer needed), MIDI I/O and much more. Cross-platform software includes the CueMix FX application and WDM/ASIO/Core Audio drivers for Mac (OS X) and Windows (8, 7 and Vista). The included AudioDesk workstation software provides 24-bit recording/editing and 32-bit mixing/processing/mastering.
