The 828es ships with standard Core Audio drivers for Mac OS X for compatibility with virtually all Core Audio-compatible apps, including:
The 828es ships with standard ASIO and Wave drivers for Windows 7*, 8 and 10 for compatibility with virtually all ASIO- and Wave-compatible audio apps, including:
Two full-color LCDs display all signal activity at a glance with detailed metering for all analog and digital I/O. Access hardware settings from a simple and convenient menu.
Renowned ESS Sabre32™ DAC technology delivers 123 dB dynamic range and the same proven, award-winning audio quality as MOTU's flagship 1248.
Round-trip latency (RTL) performance as low as 1.6 ms at 96kHz over Thunderbolt™ with high-performance DAW hosts.
Connects to your computer with Thunderbolt™, hi-speed USB 2.0 or AVB/TSN Ethernet for up to 256 audio channels (128 in and 128 out). Class-compliant firmware and industry standard drivers work with any audio apps. Connects to an iPad™ with a standard camera connection kit (adapter).
28 inputs and 32 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.
Flexible 48-input digital mixer with 7 stereo aux busses, 3 groups, access to 32 network inputs, and DSP effects, including reverb, 4-band EQ, gate and compression.
The 828es mixing and effects DSP engine delivers virtually unlimited headroom and the utmost in sound quality.
Classic reverb. Compression modeled after the legendary LA-2A compressor. EQ modeled after British analog console EQs.
Send any input to any output, or multiple outputs. Includes routing to and from the computer, plus any devices on the AVB network.
Connect an Apple® Airport™ or other Wi-Fi router with a standard Ethernet cable for wireless control of device settings, powerful 48-channel mixing and DSP effects.
Control everything from your favorite web browser on a laptop, tablet and smartphone connected to your local Wi-Fi network.
Digitally controlled analog trim on all analog inputs (mic/guitar inputs + quarter-inch TRS inputs) provides accurate adjustments in 1 dB increments.
Built-in talkback mic with front-panel "talk" button and"A/B" speaker select buttons.
Add a 2nd MOTU AVB-equipped interface with a simple CAT-5e ethernet cable. Connect up to five MOTU interfaces using a MOTU AVB Switch (sold separately).
Build a network with multiple interfaces and computers using standard AVB/TSN switches and network cabling, with ultra-low network latency, even over long cable runs (100 meters point to point). Stream hundreds of audio channels among devices and computers on the network.
Cutting-edge components deliver ultra-transparent sound with -108 dB THD+N, 118 dB dynamic range and -128 dBu EIN. Each mic channel provides individual preamp gain, pad, 48V phantom power, digital remote control and analog (pre-converter) sends for mono or stereo outboard processing.
Each headphone output can be programmed with the same or different mixes, with independent front-panel volume control.
Connect outboard digital processors, digital mixers or other gear. 16 channels of ADAT at 44.1/48 kHz, 8 channels of SMUX at 88.2/96 kHz or 4 channels of TOSLink (optical S/PDIF) up to 96 kHz. Mix and match formats among in/out ports.
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.
Dedicated time code input and output jacks. Converts SMPTE time code (LTC) to MIDI Time Code (MTC) and passes MTC on to any MTC-compatible host software.
Connect MIDI gear without the need for a separate MIDI interface.
DSP-driven phase lock engine and internal clock source produces imperceptibly low jitter characteristics (below the noise floor), even when the 828es is resolved to an external clock source via SMPTE time code.
Use the 828es to manipulate and sequence voltage-controlled modular synthesizers from a host DAW.
Includes an oscilloscope, real-time FFT, X-Y Plot, and graphic phase analysis.
Workstation software for Mac and Windows with 24-bit recording, sample-accurate editing and 32-bit mixing and mastering.
*After a ten-year run, Windows 7 has been officially end-of-lifed (EOL) by Microsoft as of January 4, 2020. Therefore, MOTU products no longer officially support Windows 7, although existing installed products (as of June 2020) should still continue to function as they have been under Windows 7. However, future updates, including drivers, may require Windows 8 or later.
