MOTU Ships 24Ai, 24Ao Audio Interfaces


MOTU is now shipping the 24Ai and 24Ao ($995 MSRP each), two new audio interfaces that offer 24 channels of high-quality analog audio input or output in a single rackspace, combined with three banks of ADAT optical for a total of 72 channels of I/O. All analog I/O is supplied on standard DB-25 D-Sub connectors or 12-pin Phoenix (Euroblock) connectors for studio and industrial installations alike.

Similar to the 1248, 8M and 16A models released by MOTU earlier this year, the 24Ai and 24Ao are equipped with DSP-driven mixing/effects and AVB Ethernet. With all five interface models, users can mix and match complementary I/O configurations and unify operation on their shared AVB audio networking platform.


The new 24Ai and 24Ao connect to a computer through universally compatible USB 2, which provides bandwidth for 24 analog channels, even for a system that includes both a 24Ai (24 analog inputs) and a 24Ao (24 analog outputs). For expanded systems, users can employ a Thunderbolt-equipped interface, such as the 16A, for 256-channel computer I/O, with the 24Ai and 24Ao units connected through AVB networking, which supports hundreds of network channels. All devices on such a network can stream audio to and from the computer, and everything can be controlled simultaneously from any computers, tablets and smartphones connected to the network.

The 24Ai and 24Ao share the same feature set and technology platform as the 1248, 8M and 16A, including very high quality analog performance, digitally controlled analog trim on analog inputs, 32-bit DAC trim on analog outputs, 48-channel mixing modeled after large format mixing consoles, DSP effects with 32-bit floating point precision, flexible matrix-style routing and splitting, stand-alone operation, Wi-Fi control, and industry-standard AVB networking with sub-millisecond network latency.
