Rupert Neve Designs quality isn't just for studios anymore. The compact RNDI-M active transformer direct box treats your instrument with the respect it deserves, delivering the true character you've been missing.

Built around a custom Rupert Neve Designs transformer and a Class-A discrete FET input stage, it delivers a rich, musical response with remarkable clarity and depth. From the lowest subfrequencies to shimmering highs, the RNDI-M maintains a strikingly natural sound, ensuring that every nuance of your tone is captured along with the power and dimension of your performance. Whether you're on stage or in the studio, it handles long cable runs with ease, thanks to a low-impedance, transformer-balanced output that eliminates signal loss while adding a touch of harmonic warmth.

With an impressive input headroom of +20.5 dBu, the RNDI-M effortlessly accommodates high-output instruments and line-level sources, making it a versatile tool for everything from thunderous bass lines to soaring synth leads. The Class-A design avoids crossover distortion, preserving the integrity of your tone while subtly enhancing it with musically rich second and third-order harmonics. Housed in a rugged steel chassis that fits on a pedalboard, this DI is not utilitarian, it's an instrument in itself, shaping and refining your signal in a way that only Rupert Neve’s legendary circuits can.
