The Steinberg UR-RT2 is an audio interface that communicates with your computer over USB 2.0. It provides six inputs, four outputs, and conversion up to 192 kHz / 24-bit. Preamps have been designed by Yamaha, providing a transparent and detailed capture of sound. Furthermore, switchable transformers are on hand courtesy of Rupert Neve Designs, a company famous for, amongst other things, their switchable harmonic distortion, which rounds out signals and lends warmth to otherwise cold audio. These transformers are beneficial for vocals, acoustic guitars, or any instrument with significant dynamic range.
On the front panel, you'll find four combination XLR-1/4" jacks that are switchable between microphone and Hi-Z configurations. Next to these inputs are the gain pots and transformer switches, between which you'll find RND's logo. Two headphone jacks, two headphone level knobs, and a main-output knob are all prominently displayed. Turn your attention to the rear of the device and you'll note the MIDI I/O, two line inputs, two main outputs, four line outputs, a USB jack, and a +48V phantom power switch for powering condenser microphones.
An SSP2 DSP chip is on hand to help you achieve zero-latency FX monitoring across many DAWs and platforms, making this device suitable for use with laptops, tablets, and desktop computers. Measuring 10.5 x 1.9 x 8.2" and weighting just over 5 lb, the unit is compact enough to take on the road.
24-bit / 192kHz via USB 2.0
The converters used in the UR-RT2 provide a maximum sampling rate of 192 kHz and 24-bit resolution.
Class-A D-PRE Mic Preamps
The UR-RT4 interfaces are equipped with Yamaha's D-PRE preamps. These deliver transparent and detailed sound.
Transformers by RND
The Rupert Neve Designs transformer featured in the UR-RT interfaces adds a natural distortion to the signal to achieve a sound with more depth and perspective. Input channels 1-2 on the UR-RT4 each feature a transformer that Rupert Neve Designs has specifically developed for audio interfaces.
Latency-Free Monitoring with FX
Thanks to the built-in SSP2 DSP and the included dspMixFx software, the UR-RT4 provides zero-latency monitoring with FX on Windows, macOS and iOS, and with every DAW.
Cross-Platform Compatibility
The UR-RT4 provides cross-platform compatibility for Windows, macOS and iOS with the included Cubase AI and Cubasis LE music software.
Loopback Function
The loopback function merges incoming signals with the playback signal and offers an easy way of streaming performances live to the Internet.
