UR22 with external USB power supply Is it possible?

Is it possible to use UR22 without PC or notebook with simple USB power supply (for example USB-s töltő, USB tápegység, 5 V/DC 1200 mA, HN Power HNP06-USB-C | Conrad ?
Does not destroy?

Hello Andras,

Why exactly do you want do work with the UR22 this way? The UR22 is designed specifically as a bus powered USB audio interface/sound card for Mac and PC. It is not designed to work as a standalone 2 channel AD/DA converter. If that is what you are looking for only the UR824 can be used in a stand alone converter mode and the UR28M can be used as a monitor controller.

Thanks!
