Open the box, connect the included cables and Experience the true tone of your guitar, bass, or line-level source with the RNDI-Cable-K.

The RNDI’s custom transformers and class-A, discrete FET amplifier deliver a beautifully musical response full of harmonic richness and detail. Its high-impedance input keeps your tone intact no matter what you throw at it, while the transformer-balanced output handles long cable runs like a champ, keeping your highs intact even 100 feet down the line. Powered by 48V phantom, the RNDI brings subtle second and third-order harmonics to the table, giving your signal unmistakable analog depth and warmth without muddying things up or introducing phase issues, great news for anyone who likes to blend DI and mic’d tracks.

But the RNDI doesn’t stop at being a great front-end. With a high input headroom of +21.5dBU, it’s built to handle hot signals from drum machines and interfaces without breaking a sweat, making it a smart way to re-amp tracks and inject a little analog mojo into your digital workflow. And if you’ve ever dreamed of running your 1000-watt amp into a DI, the RNDI’s speaker mode is here to make that dream come true. It lets you capture the full output stage of your amp, tone stack, tubes, and all, before it hits the cab, so you get the real juice without any mic bleed or stage noise. Paired with a speaker sim, it’s a killer tool for both live and studio sessions where control and tone are top priority.

Rupert Neve Designs RNDI-Cable-K Features

• Groundbreaking Direct Tone: When class-A, discrete amplifiers meet Rupert's custom transformers, good things happen to your tone. The RNDI is imbued with the unique components and design knowledge that makes it worthy of the Rupert Neve name.
• Huge Headroom: The high input headroom of +21.5dBU is capable of handling professional, line level sources without a pad- and in speaker mode, the RNDI can handle the full output of a 1000 Watt power amplifier (92 Vrms or 266Vp-p).
• Rugged Solid-Steel Frame: The rugged steel chassis features an industrial-grade powder coating, and is built to withstand the severe stresses of life on the road.
• Takes All Kinds: The RNDI has immensely consistent performance across a wide variety of sources due to its 2 MegaOhm discrete FET input and high headroom. You can confidently use the RNDI with basses, guitars, acoustic instruments, keyboards, and even line level devices. In instrument mode, you can even connect a professional line level interface output to "Re-Preamp" a previously recorded source.
• Drive Longer Lines: The low impedance transformer coupled output - below 50 Ohms - is capable of driving long lines with unrivaled high frequency performance.
• 1/4" THRU Output: In instrument mode the THRU output can feed the amplifier input for reinforcement. In speaker mode, the THRU is used to feed the amplified signal to the speaker.
• Best in Class Phase Coherence: Phase coherence is excellent at all frequencies, which keeps the sound well-balanced and natural, and is especially vital when blending the direct signal with a microphone capture of the same source.
• Ground Lift: A ground lift switch is provided on the back to help fix any problematic grounding.
• Phantom Powered: The RNDI is powered by standard 48V phantom power. Power is indicated by a blue LED on the front panel.
