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. Audio input is available via two Neutrik XLR/TRS combo inputs, both with peak indicator LEDs, and global switchable +48V phantom power, enabling the use of condenser microphones. A Hi-Z switch on input two allows for direct recording of electric guitar or bass without the need of a DI box. Latency-free hardware monitoring is available and the Mix knob allows for blending the direct signal and the output of the host. Independent headphone and main output controls provide for adjusting the monitor and phones level individually. The device also functions as a MIDI interface, allowing for connection of external MIDI devices. A Loopback function consolidates all playback tracks and input channels, routing the mix to the user's internet streaming software for easy live streaming of performances to the internet. When the function is active, incoming audio signals from a microphone, guitar, or line source will be merged to the playback signal from Cubase or other DAWs inside the computer. The merged signal will then be sent back to the computer for streaming. The interface is compatible with all major audio editing, mastering, and music production software that support ASIO, Core Audio, or WDM standards. This unit comes with a copy of Cubase AI DAW software. Based on the same core technologies as the full Cubase DAW, the AI version offers an intuitive feature set for composing, recording, editing, and mixing. Also included is Cubasis LE, a streamlined version of Steinberg's popular iOS music production app, offering professional music production on your iPad. Housed in an all-metal chassis with two TRS outputs, stable drivers, and USB connectivity, the interface provides a comprehensive feature set in a professional yet affordable device.
