How big would you expect an interface that gives you access to a total of 72 channels to be? Let the small size of the MOTU 24Ai 72-Channel USB 2.0 Audio Interface with 24 Analog Inputs and AVB Networking surprise you! Although it boasts an impressive 24 analog channels, 48 digital channels and 12 stereo buses, the interface comes in a single rack form rather than a bulky console. Full support for mobile devices lets you utilize your iPad, Android tablet, iPhone or Android phone as a controller. Because the control software is an app and not a hard drive-based program, you can utilize this interface with Linux, Mac or Windows operating systems.
