sE Electronics RNR1 Active Ribbon Microphone: The Rupert Neve Signature Sound

The sE Electronics RNR1 is a masterpiece of transducer design—the first microphone ever to bear the name of the legendary Mr. Rupert Neve. While traditional ribbon microphones are prized for their "natural" mid-range but often criticized for a dark, rolled-off high end, the RNR1 breaks the mold. This is an active ribbon microphone that delivers a massive, "big" sound with an unprecedented frequency response that extends all the way to 25 kHz.

Breaking the High-Frequency Barrier

Standard ribbons typically lose detail above 10 kHz; the RNR1 redefines the category through world-class engineering:

• Dual Rupert Neve Transformers: Designed by the man who defined the modern recording console, two custom transformers handle the critical impedance conversion while preserving ultra-wide bandwidth.
• Active Circuitry: Discrete internal circuitry compensates for the ribbon's natural roll-off, ensuring high-frequency content is captured with the same intimacy as the mid-range.
• The 2.5µm Element: After a year of research, sE developed a 2.5-micron aluminum ribbon that provides the perfect balance of flexibility and stiffness for high-fidelity performance.

Form Following Function

The RNR1’s bold, industrial look is driven by acoustic necessity:

• Scalloped Edge Design: The precision-machined edges aren't just for style; they create an acoustically ideal setting for the ribbon, minimizing diffraction and smoothing the frequency response.
• Figure-8 Precision: As a true pressure gradient microphone, it captures sound from the front and back with exceptional rejection at the sides, perfect for "Blumlein" stereo pairs or isolating instruments in a room.
• Low-Profile Aesthetics: The matte black finish ensures the microphone remains unobtrusive on stage or in the studio, absorbing light rather than reflecting it.

Studio-Ready Features & Reliability

Built to handle the rigors of professional recording:

• High SPL Handling: Capable of withstanding 135 dB, making it safe for use on loud guitar cabs, brass, and drum overheads.
• Integrated Low Cut: Features a 100 Hz switchable filter to compensate for the proximity effect when miking sources up close.
• Premium Accessories: Each RNR1 includes a custom-designed shock mount to isolate against floor vibrations, a padded sleeve, and a luxury wooden presentation case.

The sE Electronics RNR1 is a high-performance tool that captures more detail than any other ribbon on the planet. It provides the "natural" warmth you love about ribbons with the "openness" you expect from a world-class condenser.
