MOTU ships 24Ai & 24Ao audio interfaces


MOTU has announced it is now shipping the 24Ai and 24Ao, two new audio interfaces that offer 24 channels of high-quality analog audio input or output in a single rack space, combined with three banks of ADAT optical, for a total of 72 channels of I/O.

MOTU 24Ai / 24Ao

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.

“If you need lots of high-quality line-level analog I/O, the 24Ai and 24Ao are the perfect solution,” said Jim Cooper, Director of Marketing at MOTU. “They’re incredibly flexible, too. You can use them as an audio interface, optical expander, or network extension for a MOTU AVB system, complete with internal mixing, routing and effects, plus wireless control over all settings.”
