The UR22mkII from Steinberg is a two-input, two-output USB 2.0 audio interface that features dual D-PRE microphone preamps coupled with 24-bit/192 kHz converters. With a dedicated high-impedance switch, a separate headphone jack, and phantom power supply, the unit is perfect for mobile musicians, touring DJs, or the small personal writing studio. Additionally, the unit can be switched to CC (Class Compliant) mode, allowing the interface to work with the iPad 2 or later. This feature requires Apple's iPad Camera Connection Kit (iPad 2nd and 3rd generation) or Lighting to USB Camera Adapter (iPad 4th generation and iPad mini), and an external power supply with a micro-USB form factor (adapter and power supply not included). Combining the unit with an iOS audio application, such as Steinberg's Cubasis, provides an even more portable audio recording solution.
