The MOTU 112D is a flexible digital audio interface, router, format converter and standalone mixer with connectivity to your computer through ultra-fast Thunderbolt™ technology, AVB Ethernet, or class-compliant high-speed USB 2.0 (compatible with USB 3.0 and iOS).

112 Channels of Simultaneous Digital Audio I/O
The 112D provides 24 channels of AES/EBU I/O, plus 24 channels of ADAT optical I/O, plus 64 channels of MADI I/O. That all adds up to 112 in and out, for 224 simultaneous channels of digital audio I/O. All input and output channels can be active simultaneously.

64 Channels of MADI
The 112D serves as a flexible 64-channel MADI interface, router and converter with near-zero latency and flexible routing/splitting to and from the AVB network, computer, AES/EBU and optical formats. The 112D supports both 64-channel and 56-channel MADI at 1x sample rates, along with 32 channels at 2x and 16 channels at 4x.

24 Channels of AES/EBU and ADAT
Three 8-channel D-Sub connectors supply 24 channels of AES/EBU digital I/O at sample rates up to 96 kHz. Three 8-channel ADAT banks provide 24 channels of optical I/O at rates up to 48 kHz. At 88.2 or 96 kHz, all six ADAT banks support 4-channel SMUX operation for 24 channels of optical I/O at 2x sample rates.

Flexible Routing, Splitting and Format Conversion
With one click on the 112D's routing grid, you can send any input to any output, or multiple outputs. This includes routing to and from the computer, plus any devices on the AVB network. Convert any format to any other.

Ultra-Low I/O Latency
Every digital audio workflow has some latency. The only question is, how much? In the case of the 112D, the answer is not much at all. In the 112D, latency is measured in a handful of samples, from the time an audio signal first arrives at an input to its arrival somewhere else (an output, the mixer, the network or the computer). By keeping latency this low in the hardware, the 112D helps minimize latency introduced by your host software.

Thunderbolt Technology
Thunderbolt lets you connect displays, hard drives and other peripherals to your computer, along with the 112D, and the Thunderbolt bus won't even break a sweat. But more importantly, Thunderbolt gives you an astonishing 256 channels of computer I/O (128 in and out). You can use them to route audio to the physical inputs and outputs on the 112D, plus the 48-channel mixer inside the 112D, plus audio network streams. The 112D is the first and only interface to combine Thunderbolt I/O connectivity with MADI and AVB audio networking.

Audio Class-Compliant USB 2.0
Don't have a Thunderbolt-equipped computer yet? Hi-speed USB 2.0 provides across-the-board compatibility with pretty much all laptops and desktops. The 112D is USB audio class compliant, which means you enjoy OS-level USB compatibility and support, including iPad support (with Apple Camera Connection Kit - sold separately). Since USB 2.0 devices are comptaible with USB 3.0-eqipped hosts, your 112D interface is a future-proof investment in your studio.

48-Channel Digital Mixing
The 112D is equipped with a 48-channel digital mixer designed just like a large format mixing console. The 48 inputs can take signal from anywhere: the physical inputs on the 112D interface itself, audio channels from host software on your computer, audio network streams, or even mixer outputs. The mixer provides 7 stereo aux busses, 3 groups, a reverb bux that can alternately serve as a 4th group, a Main Mix bus and a separate Monitor bus that can serve as a solo bus. In essence: capable and transparent mixing.

Modeled Analog EQ and Compression
British analog mixing conoles are renowned for their musical EQ profiles. The 112D meticulously models these classic EQs to give you the very same, magical EQ response found on these coveted desks. Each input channel also provides a classic compressor module with optional peak/RMS operation. Groups and the Main Mix bus are equipped with MOTU's Leveler™, an accurate model of the legendary Teletronix™ LA-2A™ optical leveling amplifier, known for its unique and highly sought-after Automatic Gain Control (AGC) characteristics.

System Expansion and Audio Networking
The 112D network port delivers AVB Ethernet, the new industry standard developed by the IEEE for professional audio networking. Add a second MOTU AVB interface (1248, 8M, 16A, 24Ai, 24Ao or Monitor 8) with a simple CAT5e or CAT6 ethernet cable. Plus, with MOTU's AVB Switch (sold separately), you can connect up to 5 interfaces for more I/O and Wi-Fi control. This allows you to 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.

It's an AVB Audio Interface
Looking for an alternative to Thunderbolt or USB for computer audio I/O? If you have a recent Mac running OS X Yosemite (10.10) or later, you have another option: AVB Ethernet. Connect 112D's Network port to the Ethernet port on your Mac with a standard CAT5e network cable (100 meters point to point), and you can use the 112D as a standard multi-channel audio interface with any Core Audio compatible host software.

Web App Control
The software that you use to control the 112D doesn't resied on your hard drive. It's a web app served from the hardware itself. This means you can control the 112D's onboard DSP, mixing, device settings, and network audio routing from the web app software running in your favorite web browser on a laptop, table or smartphone connected by wire or Wi-Fi to your local area network. Use any web client on any platform - Mac, Windows, Linus, iOS, Android - as long as it shares the same network.

Standalone Mixing with Wireless Control
Connect to an Apple Airport™ (sold separately) 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 smartphone or table, without a computer. Great for live sound mixing!

Comprehensive Metering
The large backlit 324x24 LCD screen 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.

Quick Setup Presets
The 112D is so flexible, it can serve many roles - in the studio, on stage, and throughout an installation. The Quick Setup menu lets you instantly reconfigure the 112D for many common situations, from operation as a standard audio interface to serving as a network "snake" from one location to another. Once a preset is chosen, you can easily customix the routing grid and mixer settings to further suit your specific needs - and then save your own custom presets.
