Rupert Neve Designs RNDI-M

The RNDI-M isn’t just another direct box—it’s a purpose-built instrument DI featuring the same custom transformers and Class A FET input stage as the full-size Rupert Neve DI boxes (RNDI, RNDI-S, and RNDI-8). The difference? This model fits neatly onto any pedalboard or small setup, without compromising a single ounce of sonic integrity.

From the wide bandwidth (below 5 Hz to beyond 90 kHz) to the +20.5 dBu input headroom, the RNDI-M is designed to handle everything from delicate piezo pickups to high-output synths and drum machines—with all the rich harmonic detail Rupert Neve gear is famous for.

What’s Inside the Box?

The heart of the RNDI-M lies in its custom Rupert Neve Designs transformer and a discrete Class A FET amplifier. This combo is responsible for the DI’s natural tone, with subtle harmonic enhancements that give your sound more body and musical character.

But this isn’t just about warmth—it’s about accuracy. The RNDI-M is engineered to deliver your instrument’s tone with zero crossover distortion, ultra-low output impedance, and line-driving capability that makes it just as reliable on stage as it is in the studio.

Built for the Real World

Touring musician? Session player? Studio engineer? The RNDI-M’s steel chassis is built to handle real-world abuse. It’s powered by standard 48V phantom power, includes a ground lift switch, and features a ¼” THRU jack to send your uncolored signal to an amp or stage monitor.

Whether you’re recording at home or gigging across the country, the RNDI-M is built to go wherever great tone is needed.
