Thunderbolt™ / USB2 audio interface with DSP effects and mixing
The 828x connects to a Mac or PC with Thunderbolt™ or USB 2.0 and delivers 28 audio inputs and 30 outputs with DSP effects and mixing. You can apply 32-bit floating point effects processing to all inputs and outputs, even when operating stand-alone (without a computer). Effects include Classic Reverb, 7-band parametric EQ modeled after British analog consoles, and vintage compression modeled after the legendary LA-2A™ optical leveling amplifier. Two front-panel mic/guitar combo inputs provide transparent preamps, digitally controlled trim, 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. All analog inputs have digitally controlled analog trim controls that allow precise adjustments in 1 dB increments.
828x feature highlights
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 on all analog inputs (mic/guitar inputs + quarter-inch TRS inputs) provides accurate adjustments in 1 dB increments.
V-Limit™ overload protection — Hardware-based input limiter on the mic/guitar inputs prevents digital clipping and distortion from overloaded signal levels up to +12 dB over zero.
Front-panel control for stand-alone operation — Access any setting in your entire 828x mix directly from the front panel.
Foot switch input — Connect a standard foot pedal switch (sold separately) for hands-free punch-in and punch-out while recording. Or map the pedal to any keystroke function in your host software.
Direct Digital Synthesis™ (DDS) — DSP-driven phase lock engine and internal clock source produces imperceptibly low jitter characteristics (below the noise floor), even when the 828x is resolved to an external clock source via SMPTE time code.
Time code support — Directly resolves to (or generates) time code via any quarter-inch input or output, without the need for an extra synchronizer.
DC-coupled TRS outputs — Use the 828x with Volta™ (sold separately) to manipulate and sequence voltage-controlled modular synthesizers from a host DAW.
Instrument tuner and audio analysis tools — Includes an oscilloscope, real-time FFT, X-Y Plot, and graphic phase analysis.
