Eight channels of digital audio I/O and conversion with SRC
Four channels of professional AES3 (AES/EBU) digital I/O, plus four channels of standard S/PDIF digital audio I/O, with sample rate conversion on all inputs.
Flexible, router, converter and splitter
Send any input to any output, or split to multiple output channels. Convert any format to any other (AES3, S/PDIF, AVB-TSN and USB). Includes routing to and from the computer, plus any devices on the AVB-TSN network.
Stand-alone operation with wireless control
Connect a standard Wi-Fi router with a standard Ethernet cable for wireless control of device settings, routing/splitting, powerful 48-channel mixing and DSP effects.
DSP mixing and effects processing
Flexible 48-input digital mixer with 7 stereo aux busses, 3 stereo groups, access to 32 network inputs, and DSP effects, including reverb, 4-band EQ, gate and compression.
Ultra-low latency and proven, high-performance MOTU drivers
Universal connectivity over high-speed USB 2.0 (3.0 and iOS compatible) and AVB. Renowned drivers deliver industry-leading low latency and rock solid performance.
Comprehensive metering
The full-color LCD lets you view all signal activity at a glance with detailed metering for all I/O. Access hardware settings from a simple and convenient menu.
Convenient headphone monitoring
Assignable front-panel headphone output with volume control allows for monitoring of any stereo channel pair.
Word clock I/O
Standard word clock input and output for resolving to other digital audio gear or house sync.
32-bit floating point processing
The 8D's mixing and effects DSP engine delivers virtually unlimited headroom and the utmost in sound quality.
Modeled vintage effects processing
Classic reverb. Compression modeled after the legendary LA-2A compressor. EQ modeled after British analog console EQs.
Web app control from any device
Control everything from your favorite web browser on a laptop, tablet and smartphone connected to your local Wi-Fi network.
System expansion
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).
AVB-TSN audio networking
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.
Audio analysis tools
includes a full-screen real-time FFT display, spectrogram “waterfall” display, full-featured oscilloscope, X-Y plot and phase analyzer.
AudioDesk
Includes AudioDesk workstation software for Mac and Windows with 24-bit recording, sample-accurate editing and 32-bit mixing and mastering.
