The Motu 112D is a flexible digital audio interface, router, format converter and stand-alone mixer with connectivity to your computer through ultra-fast thunderbolt technology.

The seventh in MOTU's new series of high-end audio interfaces, the 112D serves as the flagship digital interface of the new line, offering 24 channels of AES/EBU, 24 channels of ADAT optical and 64 channels of MADI (AES10) for a total of 112 simultaneous digital I/O channels, all in a single rack space. Operating on its own or as a component of a MOTU AVB network system, the 112D shares the many powerful mixing, routing, networking and wireless control features found in MOTU's award-winning AVB interface lineup.

The 112D can serve as a central digital hub, allowing you to unify your mixing console, audio workstation and other digital audio gear, and then link it all to an AVB audio network with sub-millisecond routing, hundreds of audio channels, standard Ethernet infrastructure and long, affordable cable runs.
112 simultaneous digital audio channels
24 channels of AES/EBU, plus 24 channels of ADAT optical, plus 64 channels of MADI, for 112 total channels digital audio I/O. All input and output channels can be active simultaneously.

64 channels of MADI
Serves as a 64-channel MADI interface, router and converter with near-zero latency and flexible routing and splitting to/from the AVB network, computer, AES/EBU and optical. Supports 56-channel mode, 32-channel mode and 1x/2x/4x clock modes.

24 channels of AES/EBU and ADAT optical up to 96 kHz
Three 8-channel (D-sub) banks of AES/EBU at sample rates up to 96 kHz. Three 8-channel banks of ADAT optical at rates up to 48 kHz; six banks of ADAT at 2x sample rates (24 channels).

Flexible routing, splitting and format conversion
Send any input to any output, or multiple outputs. Includes routing to and from the computer, plus any devices on the AVB network. Convert any format to any other.

256 channels of network audio I/O for your host computer
Record and monitor up to 128 networked audio channels in and out, simultaneously, through the Thunderbolt connection to a host computer.

Universal connectivity
Connects to a computer with Thunderbolt, standard AVB Ethernet or audio class compliant high-speed USB 2.0 (compatible with USB 3.0 and iOS). Discovery app and web app software works alongside any host audio software.

On-board DSP with mixing and effects
Flexible 48-input digital mixer modeled after large format mixing consoles, with 12 stereo busses and DSP effects, including reverb, 4-band EQ, gate, and compression.

32-bit floating point processing
The 112D'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.

System expansion and audio networking
Add a 2nd MOTU AVB interface (1248, 8M, 16A, etc.) 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 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.

256 channels of network audio I/O for your host computer
Record and monitor up to 128 networked audio channels in and out, simultaneously, through the Thunderbolt connection to a host computer.

Web app control
Control on-board DSP, mixing, device settings, and network audio routing from web app software running in your favorite browser on a laptop, tablet or smart phone connected by wire or Wi-Fi to your local area network.

Stand-alone mixing with wireless control
Connect an Apple Airport or other Wi-Fi router directly to the 112D with a standard Ethernet cable and control the 112D's powerful mixing and DSP effects from your smart phone or tablet, without a computer. Great for live sound mixing.

Comprehensive metering
The large backlit 324 x 24 LCD lets you view 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.

Includes AudioDesk workstation software for Mac and Windows with 24-bit recording, sample-accurate editing and 32-bit mixing and mastering.
