The MOTU 112D Thunderbolt Audio Interface is a hugely versatile device with the ability to be either a digital audio interface, router, format converter, and stand-alone mixer. It's also versatile when it comes to connections, connecting to your computer over insanely fast Thunderbolt technology, AVB Ethernet or class compliant USB 2.0.
The 112D gives you 24 channels of AES/EBU I/O, 24 channels of ADAT optical I/O and 64 channels of MADI I/O. All this totals to an impressive 112 simultaneous digital I/O channels. The 112D works as a zero latency 64-channel MADI-to-AVB converter and router with flexible splitting and routing to and from your AVB network. Furthermore, it supports both 64 channel and 56 channel MADI at 1x sample rates, as well as 32 channels at 2x and 16 channels at 4x.
24 channels of AES/EBU digital I/O is supplied by three 8 channel D-sub connectors, giving sample rates of up to 96kHz. Three 8-channel ADAT banks provide 24 channels of optical I/O at rates of up to 48kHz. 4-channel SMUX operation is supported by all six ADAT banks, giving 24 channels of optical I/O at 2x sample rates.
When working in an audio workflow, you're going to experience some latency. But, when working with the 112D the latency will be very, very low. Latency is measured in a handful of samples from the time a signal first arrives at an input, to its arrival somewhere else. Keeping latency low in the hardware, the 112D helps minimize latency introduced by your host software.
Thunderbolt technology has a massive bandwidth, allowing you to connect hard drives, displays and other accessories, along with the 112D. All this and the Thunderbolt bus won't even break a sweat, providing an outstanding 256 channels of computer I/O (128 in and out). You can use these channels to route audio to the physical inputs and outputs on the 112D, as well as the internal 48 channel mixer and the audio network systems.
If you don't have a Thunderbolt equipped device, hi-speed USB 2.0 provides compatibility with pretty much all desktops and laptops. By being USB audio class compliant, you can enjoy OS-level USB compatibility and support. You can even connect the 112D to an iPad using the Apple camera connection kit. USB 2.0 is compatible with USB 3.0 devices, meaning the 112D is a future proof device.
The powerful DSP on the 112D allows it to mixing you could only do on a big console, giving you 48 channels, 12 stereo busses and 32-bit floating point effects processing. These include modelled analogue EQ, vintage-style compression and classic reverbs.
The 112D is completely cross compatible with other MOTU AVB interfaces, allowing you to connect one to another over a single Ethernet cable. With the optional MOTU AVB Switch, you can add more I/O. This allows you to build your AVB network with multiple switches and extremely low latency. Streaming hundreds of channels amongst devices and computers on your network has never been easier.
