Roland DUO-Capture EX UA-22 USB Audio Interface (Discontinued)
The Roland 2-channel DUO-Capture EX UA-22 is highly rated for its portability. It can run on 3 x AA batteries, which allows it to work with mobile devices even in locations where a power outlet is unavailable. The use of batteries is especially useful when pairing the DUO-Capture with laptops, tablets and other mobile computing devices. Traditional power options like USB bus power and AC Adapter (sold separately) are also available so you only use batteries when its actually needed.
It's also relatively light, weighing in at around 1lb, which makes it all the more viable for mobile recording. But its not just about mobility because this interface comes packed with the same VS mic preamps that are used on Roland’s high-end digital mixers.
Finally, it comes with enough input/output options (2-channel) to meet the needs of most home studios, and includes MIDI in and out.

Overall response to the Roland DUO-Capture EX UA-22 is mostly positive, impressing many users with its build quality and portability. Other reviews were happy with its painless installation and quick setup for Mac, Windows and even iOS, making it viable for inexperienced users who want to try their hands at home recording.
There is some concern over the lower sampling rate, but many believe that sampling rates above 44kHz should be the least of your sound quality concerns. There are also a few concerns from users who had driver issues right after updating their operating system, but these types of problems are usually solved after updating software drivers.
We had been recommending the Roland Duo-Capture EX UA-22, however after a thorough re-examination of the category we found more highly rated options had become available by June 2018. You can see our current recommendations in the guide: The Best Cheap Audio Interfaces Under $200.
