112 Channels of Digital Audio I/O, 24 Channels of AES/EBU I/O


The D112 from MOTU is a digital audio interface, router, format convertor, and stand-alone mixer offering 224 channels of simultaneous inputs and outputs with Thunderbolt, AVB Ethernet, and USB connectivity. The 1U 19" rackmountable device features 24 channels of AES/EBU I/O and 24 channels of ADAT optical I/O, plus 64 channels of MADI I/O. Additional I/O can be added to the system through AVB networking.

The audio interface serves as a flexible 64-channel MADI interface, router, and convertor with low-latency and flexible routing/splitting to and from the AVB network, computer, AES/EBU, and optical formats. Three 8-channel D-sub connectors supply 24 channels of AES/EBU, while six banks of ADAT support up to 24 channels of optical I/O at 96 kHz.

Using Thunderbolt connectivity, the audio interface can stream 128 audio channels in and 128 channels out to the interface's physical outputs, the DSP-powered 48-channel mixer, or AVB audio network streams. The interface can also use high speed USB 2.0 (3.0 compatible) using class compliant drivers to work with most digital audio workstations.

The 48-channel digital mixer can mix physical inputs on the interface, audio channels from your host computer software, AVB audio network streams, or mixer outputs. It features seven stereo auxiliary busses, three groups, a reverb bus that can serve as an alternate 4th group, a main mix bus, and a separate monitor bus that can function as a solo buss.

The mixer includes 32-bit floating point precision DSP-powered models of three British analogue console AEQ profiles, a classic compressor module with optional peak/RMS operation, and a model of the legendary Teletronix LA-2A optical levelling amplifier with automatic gain control (AGC) characteristics. Each input channel strip features a high-pass filter, a gate, a four-band parametric AEQ, and a compressor.

The device's digital routing matrix allows you to route any source signal including digital interface input, computer channel, mixer bus output, or network stream to any destination such as an interface output, host software input, mixer input, or any other device (or computer) on the AVB network. A single input or stereo pair can also be split and sent to multiple destinations.

This interface features an AVB Ethernet port that adopts the AVB industry networking standard for transporting high-bandwidth, low-latency audio and video over Ethernet. It was developed by the IEEE and enables connection to a second MOTU AVB audio interface (1248, 8M, or 16A) via a CAT-5E or CAT-6 Ethernet cable. The standard is open meaning it is not proprietary and will allow for open interoperability across different devices and brands.

The system can be further expanded through connection to a MOTU AVB Switch (sold separately), for five total devices and the capacity to stream over 512 channels on the network. Sixteen 8-channel network streams may be broadcast while simultaneously listening to sixteen 8-channel network streams. The AVB network provides its own network-wide time base for phase locking all connected devices and also allows one of the connected devices to be assigned as the master clock. An added benefit of the AVB network standard is the automatic device discovery for self-configuration, 100 metre cable runs, as well as the system's Stream Reservation Protocol which provides guaranteed Quality of Service (QoS) and an uninterrupted point-to-point network connection.

The audio interface's on-board DSP, mixing, device settings, and network audio routing can all be controlled through a web application running on a web browser from a laptop, tablet, or smartphone connected by wire or Wi-Fi to your local area network. This allows the interface to be controlled using Mac, Windows, Linux, iOS, and Android devices provided they share the same network. By connecting an Apple Airport or other Wi-Fi router directly to the interface with a standard Ethernet cable, the mixing and DSP controls of the interface can be managed using a smartphone or tablet, without the need for a computer. This is useful for situations such as mixing live sound. A total of up to 12 independent stereo mixes can all be independently controlled by different engineers or musicians via Wi-Fi connected iPhones or iPads.

The device includes a collection of quick setup presets designed for different applications in the studio, on stage, or for installed sound such as a recording interface or network snake. Presets can be customised using the digital routing matrix as well as saved for future recall.

Australian Shipping Via DHL
DHL offers a great express shipping service to Australia from New Zealand. We are proud to be able to offer express shipping to main cities on the east coast of Australia, within the same timeframe ( If not quicker ) than local Australian courier companies. Prior to the Covid-19 outbreak, service standards for these main centers was overnight. However these services have been impacted greatly, and as such the overnight service has been suspended. Overnight shipping will likely resume once things have returned to normal.

Qualifying main centers include:

  • Brisbane
  • Sydney
  • Adelaide

Whilst this service is extremely efficient and will likely be delivered within 1-2 days 99.9% of the time, it cannot be guaranteed. In the case where something were to go wrong with your delivery and it doesn’t arrive within the specified time frame, in most cases it will be delivered by the next day.

While not all major cities are eligible for overnight delivery, they still benefit from this great service. Other centers throughout Australia will have a typical delivery ETA of 2-4 days. (Excluding rural delivery address where this ETA can be extended to an additional three or more days).

If you require urgent shipping and you don’t reside in one of the cities stated above, please contact us and we can find a solution that works best for you.

Please Note: Shipping via DHL is not available to PO boxes and/ or parcel boxes etc.
