Introducing the 24Ao
Two new audio interfaces with 24 analog channels in one rack space, superb audio quality, AVB audio networking, and large console style mixing with 48 channels and 12 stereo busses
The 24Ao are two new members of MOTU's high-end audio interface lineup that includes the 1248, 8M and 16A. You can mix and match their complementary I/O configurations and unify operation with their shared AVB audio networking platform.
72 audio channels
24 channels of analog, plus three 8-channel banks of digital I/O
The 24Ao offers twenty-four analog outputs. Both units include three 8-channel ADAT optical banks, for a total of 72 channels each (24 analog plus 48 optical). Use the 24Ao to add analog I/O to your computer, or as a flexible optical expander and mixer. Or both!
All analog I/O is supplied on multi-channel DB-25 D-sub connectors and Phoenix connectors for convenient, flexible wiring into studio and industrial installations alike. If you need individual quarter-inch connectors, check out the 16A interface.
Superb audio quality
The 24Ao employ the same industry-recognized analog design as MOTU's groundbreaking 1248, 8M and 16A audio interfaces.
24Ao Line Out
Audio class compliant USB 2.0
Broad compatibility with future-proof connectivity
Hi-speed USB 2.0 provides across-the-board compatibility with pretty much all laptops and desktops. The 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 24Ao interface is a future-proof investment in your studio.
48-channel digital mixing
Control up to 12 separate stereo mixes
The 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 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
Vintage processing with 32-bit floating point precision
British analog mixing consoles are renowned for their musical EQ profiles. The 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
Put the ultimate patch-bay at your fingertips
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
Expand your system with more I/O and Wi-Fi control
Connect up to five MOTU interfaces using a MOTU AVB Switch (sold separately).
The network port on the 24Ao introduces AVB Ethernet, the new industry standard developed by the IEEE for professional audio networking. Add a second MOTU AVB interface (24Ao, 1248, 8M, or 16A) with a simple Cat-5e or CAT-6 ethernet cable.
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
Control everything from your laptop, tablet, and smart phone
The software that you use to control the 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.
Stand-alone mixing with wireless control
Control everything from your iPad or iPhone
Connect an Apple Airport ™ or other Wi-Fi router directly to the 24Ao with a standard Ethernet cable and control powerful mixing and DSP effects from your smart phone or tablet, without a computer. Great for live sound mixing!
View all I/O activity at a glance
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
Completely transform your MOTU interface with one click
The 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 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.
