The MOTU 24Ai AVB/USB 2.0 audio interface packs the analog input you need into a handy single-rackspace unit. This networkable audio interface combines MOTU's legendary sound quality with powerful onboard DSP mixing, 32-bit signal processing, and high-speed USB 2.0 computer connectivity. The result is a 48-in/24-out interface that's great for recording and live sound rigs. A set of 24 analog inputs on D-sub and Phoenix connecters make the 24Ai ideal for tracking in the studio, grabbing signal from onstage, or capturing direct outputs from your analog mixer. What's more, there are 24 channels of ADAT optical digital I/O onboard, so expanding your system is easy.

72 Audio Channels

The 24Ai offers twenty-four balanced analog inputs in a single rack space. The 24Ao offers twenty-four analog outputs. Both units inculde three 8-channel ADAT optical banks, for a total of 72 channels each (24 analog plus 48 optical). Use the 24Ai and 24Ao to add analog I/O to your computer, or as a flexible optical expander and mixer. Or both!

Superb Audio Quality

The 24Ai and 24Ao employ the same industry-recognized analog design as MOTU's groundbreaking 1248, 8M and 16A audio interfaces.

Audio Class Compliant

Hi-speed USB 2.0 provides across-the-board compatibility with pretty much all laptops and desktops. The 24Ai and 24Ao are USB audio class compliant, which means you enjoy OS-level USB compatibility and support, including iPad support (with a camera connection kit). Since USB 2.0 devices are compatible with USB 3.0-equipped hosts, your 24Ai /24Ao interface is a future-proof investment in your studio.

48-Channel Digital Mixing

The 24Ai and 24Ao are 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 24Ai / 24Ao 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 bus 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: comprehensive and transparent mixing.

Modeled Analog EQ And Compression

British analog mixing consoles are renowned for their musical EQ profiles. The 24Ai and 24Ao meticulously model 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.

Matrix Routing And Splitting

With one click on the routing grid, you can route any source signal to any destination. Sources can be analog or digital inputs on the interface, computer channels, mixer bus outputs, or audio network streams from other devices on the network. Destinations include interface outputs, host software inputs, mixer inputs, or any other device (or computer) on the AVB network. You can even split any single input (or stereo pair) to unlimited multiple output destinations.

System Expansion And Audio Networking

The network port on the 24Ai and 24Ao introduces AVB Ethernet, the new industry standard developed by the IEEE for professional audio networking. 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 (hundreds of meters). Stream hundreds of audio channels among devices and computers on the network.

Web App Control

The software that you use to control the 24Ai and 24Ao doesn't reside on your hard drive. It's a web app served from the hardware itself. This means you can control the on-board DSP, mixing, device settings, and network audio routing from the web app software running in your favorite web browser on a laptop, tablet or smart phone connected by wire or Wi-Fi to your local area network. Use any web client on any platform - Mac, Windows, Linux, iOS, Android - as long as it shares the same network.

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.

Quick Setup Presets

The 24Ai and 24Ao are so flexible, they can serve many roles - in the studio, on stage, and throughout an installation. The Quick Setup menu lets you instantly reconfigure the 24Ai and 24Ao 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 customize the routing grid and mixer settings to further suit your specific needs - and then save your own custom presets.
