The UR12 from Steinberg is a two input/two output USB audio interface featuring a single D-PRE microphone preamp with phantom power, housed in a compact and rugged chassis. The 24-bit/192 kHz capable converters provide excellent detail and dynamics, and the unit is compatible with most major audio related software. Cubase AI software for recording, composing, editing and mixing is included. When connected to Apple's iPad (requires optional accessories), the interface provides a portable and intuitive production system. While this application requires an external power supply to function, the 5 VDC input can also be used to provide power stability in other situations. Latency-free hardware monitoring and a loopback function for Internet streaming make this compact interface an attractive choice where large channel counts are not needed.
