The UR-RT4 is a premium six input, four output USB 2.0 audio and MIDI interface with switchable Rupert Neve Designs transformers on the front inputs. Combined with the onboard, high-quality D-PRE preamps, the Rupert Neve Designs transformers deliver a musical, more expressive sound with rich harmonics, which is especially beneficial for vocals, acoustic guitar and other instruments with a versatile dynamic range.

Offering a studio quality, mobile production platform with a range of input/output options for laptop and iPad, the onboard SSP2 DSP chip also delivers zero-latency FX for monitoring. The robust UR-RT4 is engineered to offer outstanding quality for its price class, making it the ideal portable production interface for PC, Mac or iOS.

6 x 4 USB 2.0 Audio Interface with 4 x Rupert Neve Designs Transformers & D-PRE

24-bit/192kHz USB 2.0

The high-class converters used in the UR-RT interfaces are top of the range and provide a maximum sampling rate of 192 kHz and 24-bit resolution.

Class-A D-PRE mic preamps

The UR-RT interfaces are equipped with Yamaha’s highly acclaimed D-PRE preamps that deliver truly transparent and beautifully detailed sound, unrivaled in this product class.

RND Transformer

The Rupert Neve Designs transformer featured in the UR-RT interfaces adds a natural distortion to the signal to realize a sound with more depth and perspective.

Latency-free monitoring with FX

Thanks to the built-in SSP2 DSP and the included dspMixFx software the UR-RTs provide zero-latency monitoring with FX on Windows, macOS and iOS and with every DAW.

Cross-platform compatibility

The UR-RT audio interfaces provide 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.

The Rupert Neve Designs transformer

Mr. Rupert Neve is undoubtedly a legend in the professional audio field. The transformer circuitry is one of the key factors in his numerous vintage designs and also in the latest devices from Rupert Neve Designs, which gives a very appealing touch of natural compression and saturation to the sound.

Input channels 1-4 on the Steinberg UR-RT4 each feature a transformer that Rupert Neve Designs has specifically developed for audio interfaces. With this transformer, a natural distortion can be added to the signal to realize a sound with more depth and perspective, while maintaining the natural sound of the DPRE itself when the transformer is disabled.

The D-PRE: Beyond precision

The virtues of the Yamaha-designed D-PRE have been sung by industry veterans and trade press alike since the introduction of this class-leading preamp. A sumptuously detailed high-end, immaculate dynamic response and a rich, rounded low-end sound are the hallmarks of this very special preamp. The UR-RT2 and UR-RT4 feature two D-PRE preamps, each offering stellar recording quality unmatched in this price class. And to faithfully capture and replay the warm, transparent sound of the D-PRE, the UR-RTs feature AD and DA conversion stages with up to 24-bit, 192 kHz resolution.

UR-RT4 setup scenarios


Front panel connectivity

Recording a small band or group is one of the UR-RT4’s many inherent strengths: one mic on input 1, a guitar plugged directly into the UR-RT4 on input 2, and input 3 and 4 acting as a stereo pair recording a digital instrument like a synth or keyboard.


UR-RT4 connection example with laptop, rear panel

MIDI-based composers looking for a new interface for composing on a laptop need look no further! Hook up your keyboard to the UR-RT4 MIDI port, and your monitor speakers to the main output.


UR-RT4 connection example with iPad, rear panel

Connecting an iPad requires the Apple iPad Camera Connection Kit. Once attached, the iPad can host music apps like Steinberg’s Cubasis, while the MIDI I/O ports hook up to sound modules, a MIDI keyboard or drum pad controller. Monitor speakers pumping out the main mix are attached to the dedicated main output sockets.

Full DAW integration with dspMixFx

The UR-RT series integrates seamlessly with Cubase and almost any other DAW, delivering latency-free monitoring with DSP-powered FX, via the onboard SSP2 DSP chip and latest dspMixFx technology. This provides a fully integrated, DSP-based monitoring setup wherever you are and with whichever DAW you use.

Use cases

Exceptional sound on the go…

Thanks to its four combo inputs with switchable Rupert Never Designs input transformers and state-of-the-art D-PRE preamps, the UR-RT4 delivers exceptional audio quality and musicality, yet its rugged, portable form means that it is perfect for recording on the go. Ideal for use with Mac/PC laptops and iPad, it has a total of six inputs, plus six outputs and twin headphone sockets with independent volume controls. This means it can be used for a wide range of mobile applications, without you ever having to worry about lack of facilities.

… and in the studio.

The UR-RT4 is ideal for mobile use, but is equally at home in the studio, making it the perfect “one-stop shop” for the musician or audio professional who needs a thoroughly versatile solution. Recording on iPad or laptop, but then need to continue the process in the studio? The UR-RT4 handles both with ease, meaning you don’t need a separate audio/MIDI interface for each. The UR-RT4 makes it easy to record on an iPad app like Cubasis, Steinberg’s streamlined, multi-touch sequencer, and then transfer the project to a computer running Cubase for more comprehensive production tasks, without needing a second audio interface.

Sound as professional as the professionals

Home and project sound recordists may look with envy at the facilities of high end recording studios but, with its four switchable Rupert Neve Designs input transformers, exceptional D-PRE preamps, switchable +48 V phantom power and Hi-Z inputs, the UR-RT4 provides the tools to make even the most humble recording set up sound exceptional. Renowned for their rich musicality, Rupert Neve Designs products are used by many audio professionals, while D-PRE preamps are a feature of industry-leading digital mixing systems by Yamaha. The UR-RT4 brings these exceptional input facilities within reach of much humbler budgets.

Monitoring flexibility

The UR-RT4 features exceptional input facilities, but its monitoring and output flexibility is no less impressive. Its dspMixFx technology delivers fantastic-sounding, latency-free monitoring, while twin headphone sockets with independent volume controls mean that two musicians, or a musician and a producer, can work together in perfect harmony. In addition, six TRS output sockets mean output audio can be routed to different destinations, as required — for example several pairs of monitors can be connected for A/B-ing mixes on different speaker combinations.

Master of multitasking

Nowadays we are blessed with so many different ways to make and capture music that a piece of equipment able to be used for all of them is worth far more than its cost. Whether you are writing songs, recording a choir or string quartet, DJing, playing virtual instruments, recording a live band, capturing the sounds of nature on location, jotting down musical ideas, performing a gig with backing tracks or a myriad of other scenarios, the UR-RT4 has the facilities required to achieve them quickly and with exceptional quality.

Make your recordings literally sing

Capturing the real essence of voices and acoustic instruments can be a challenge. They have an inherent musicality that the organic reception of the human ear reproduces, yet the cold, hard ones and zeros of digital recording can struggle to truly ensnare. The four Rupert Neve Designs input transformers add an analog element to recordings made on the UR-RT4, bringing out the full expressive, harmonic richness of sounds, which are then captured by the highend, industry-leading D-PRE preamps.
