U-22 Handy Audio Interface

The U-22 is the essential mobile recording and performance interface, with an innovative 2-in/2-out ultra-portable design that makes it easy to connect to a laptop or iPhone/iPad and create great-sounding audio anywhere. The interface features a high-performance, low-noise mic preamp so you can record vocals, instruments, and more with pristine sound quality—at resolutions up to 24-bit/96 kHz. The U-22 delivers the same excellent sound as our U-44 and U-24, with an even more compact form factor.
