MOTU 24AI USB-2 / AVB Ethernet Audio Interface with 24 Channels of Analog Input and DSP

The MOTU 24Ai audio interface provides 24 analog channels within a single rack space, boasting exceptional audio fidelity, AVB audio networking capabilities, and expansive console-style mixing featuring 48 channels and 12 stereo busses. It joins MOTU's prestigious range of high-end audio interfaces, alongside models such as the 1248, 8M, 16A, and 24Ao. Users have the flexibility to combine various I/O configurations seamlessly and streamline operations through the integrated AVB audio networking platform.

Features:

• 72 simultaneous audio channels - 24 high-quality, balanced analog inputs on three banks of multi-channel connectors (DB-25 D-sub and Phoenix), plus three banks of 8-channel ADAT optical for 48 inputs and 24 outputs.
• Universal connectivity - Connects to a computer with audio class compliant high-speed USB 2.0 (compatible with USB 3.0 and iOS). Discovery app and web app software works with any host audio software.
• On-board DSP with mixing and effects - Flexible 48-input digital mixer modeled after large format mixing consoles, with 12 stereo busses and DSP effects, including reverb, 4-band EQ, gate, and compression.
• 32-bit floating point processing - The 24Ai's mixing and effects DSP engine delivers virtually unlimited headroom and the utmost in sound quality.
• Modeled vintage effects processing - Classic reverb. Compression modeled after the legendary LA-2A compressor. EQ modeled after British analog console EQs.
• System expansion - Add a 2nd MOTU AVB interface (24Ao, 1248, 8M or 16A) with a simple Cat-5e ethernet cable. Connect up to five MOTU interfaces using a MOTU AVB Switch (sold separately).
• AVB 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.
• Flexible matrix routing and splitting - Send any input to any output, or multiple outputs. Includes routing to and from the computer, plus any devices on the AVB network.
• Stand-alone mixing with wireless control - Connect an Apple Airport or other Wi-Fi router directly to the 24Ai with a standard Ethernet cable and control the 24Ai's powerful mixing and DSP effects from your smart phone or tablet, without a computer. Great for live sound mixing.
