CAPTURE THE TRUE SOUND OF HARMONICALLY-RICH VOCALS AND INSTRUMENTS

Have you ever struggled to capture the true essence of vocals and acoustic instruments? You are not alone.

With the UR-RT4, you have four Rupert Neve Designs input transformers which add an analog element to recordings, bringing out all of their expressive, harmonic richness. These are captured by the industry-leading, transparent D-PRE preamps to reproduce the full dynamic range in exquisite detail.
