The 24Ai and 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.
The 24Ai offers twenty-four balanced analog inputs in a single rack space. 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 24Ai and 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.
The 24Ai and 24Ao employ the same industry-recognized analog design as MOTU's groundbreaking 1248, 8M and 16A audio interfaces.
|24Ao Line Out||123 dB||-110 dB|
|24Ai Line In||110 dB||-102 dB|
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.
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.
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.
Connect up to five MOTU interfaces using a MOTU AVB Switch (sold separately).
The network port on the 24Ai and 24Ao introduces AVB Ethernet, the new industry standard developed by the IEEE for professional audio networking. Add a second MOTU AVB interface (24Ai, 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.
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.
Connect an Apple Airport™ or other Wi-Fi router directly to the 24Ai or 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!
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.
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.
