The UA-22 DUO-CAPTURE EX from Roland is a two input/two output USB audio interface housed in a compact road-tough metal case, perfect for traveling musicians. It features two digitally controlled microphone preamps (VS Preamps) made from the same components as the preamps found in company's V-STUDIO 700 and M-400 digital mixer. The interface is compatible with Windows, Mac OS X, and iOS operating systems.
Two combo XLR/TRS inputs are provided that deliver phantom power for use with condenser microphones. Additionally, one of the inputs accepts a Hi-Z instrument input for connecting electric guitars, etc. The unit can also be used as a front end for the Apple iPad equipped with the appropriate iOS recording apps, or the USB-MIDI interface used to control iOS apps with electronic instruments such as MIDI keyboards, V-Drums, etc.
The three-way power supply offers operational convenience with a choice of sources-the computer's USB bus, batteries, or an optional AC adapter. The wide-ranging power supply is designed to deliver clean balanced input and output, and when powered by the computer's USB bus, the unit internally regenerates the incoming power, ensuring the ideal voltage for optimal sound quality.
