Rupert Neve Designs RNDI-M – Compact Instrument Direct Box with Signature Tone
The RNDI-M from Rupert Neve Designs brings the stunning tone and clarity of its award-winning counterparts to a more compact and pedalboard-friendly format. Featuring the exact same custom Rupert Neve transformers and discrete FET input stage as the best-selling RNDI, RNDI-S, and RNDI-8, the RNDI-M delivers uncompromised sonic power in a rugged, streamlined chassis. It’s the perfect solution for musicians and engineers looking for world-class instrument DI performance in a space-saving design.
Overview
The RNDI-M is an instrument direct injection (DI) solution for electric guitars, basses, synthesizers, keyboards, piezo pickups, and any other instrument-level source. Built around Rupert Neve’s renowned custom transformers and a discrete, Class-A FET circuit, it offers incredible tonal clarity, musicality, and a natural sound that spans from below 5Hz to well beyond 90kHz. It can handle input levels up to +20.5dBu, providing unparalleled headroom and a distortion-free signal path. Whether you’re in the studio or on stage, the RNDI-M ensures optimal performance and vibrancy for your instruments.
Signature Sound
The RNDI-M’s unique sound is largely due to the combination of Rupert Neve’s custom-wound transformers and the Class-A, discrete FET input stage. These elements together provide a tonally rich, transparent sound that maintains a musical response. The custom transformer adds harmonic complexity and dimension to the sound while providing passive isolation and driving long cable runs with ease.
Features:
- Groundbreaking Direct Tone: The class-A, discrete amplifier combined with custom Rupert Neve transformers provides a tonal response that’s unmatched in DI boxes.
- Huge Headroom: The RNDI-M offers a maximum input level of +20.5 dBu, handling not only instruments but also keyboards, drum machines, and even pre-recorded material.
- Rugged Solid Steel Frame: Designed to withstand the rigors of the road, the RNDI-M features a robust steel chassis.
- Use on a Variety of Sources: The high impedance input stage and high headroom make it perfect for use with guitars, basses, keyboards, synths, drum machines, and more.
- Drive Longer Lines: The low-impedance transformer coupled output excels at driving long lines with minimal signal loss.
- 1/4″ THRU Output: Use the THRU output to send the direct signal to an amplifier without signal degradation.
- Ground Lift: The rear panel ground lift switch isolates the circuit ground to eliminate potential grounding issues.
- Phantom Powered: The RNDI-M is powered by standard 48V phantom power, with a blue LED indicating power status.
