RNDI-8 - Overview

Legendary tone, unquestionable reliability. Eight channels of the superb-sounding RNDI in one rack space.
With over 25,000 channels shipped since its launch in 2015, the RNDI is firmly established as the direct interface of choice for many of the world's most discerning musicians and engineers. Its custom transformers and discrete FET amplifiers deliver a vibrancy and clarity that captures the full harmonic depth of any source, and its unquestionable reliability has led to its adoption by thousands of touring artists.

The Rupert Neve RNDI-8 puts eight channels of this beloved circuit into a single rack space, making it the ideal solution for high-end stage rigs, studios, and synth enthusiasts. With the RNDI-8, stunning direct sound doesn't require extra work - it's just there.

The RNDI-8 consists of eight independent channels of RNDI Active Transformer Direct Interface in a single rack space, providing instrument direct injection for electric guitar & bass, synthesizer, keyboard, piezo pickup, or any other instrument-level source.

The discrete, class-A circuit topology is built around Mr. Rupert Neve's custom transformers, resulting in outstanding sonic performance and supremely natural sound from 5Hz all the way out to well beyond 90kHz. Each channel can handle input levels up to +21dBu (+31dBu with the pad engaged), the low impedance transformer-coupled output drives long lines with minimal loss, and the rugged chassis' steel construction is designed for a lifetime of stage and studio use.

The RNDI-8's signature sound stems from the custom-designed transformers and class-A, discrete FET input amplifiers. The carefully designed union of these two elements is key to the RNDI-8's unique accuracy, tone, and response.

The Eight Custom Transformers
The RNDI-8's custom-wound output transformers provide isolation while adding musical harmonics and dimension to the sound. The low impedance, transformer-balanced outputs excel at driving long cable runs, and the performance is consistent regardless of the connected equipment. This is important for both live and studio environments where the unamplified signal may travel 100ft or more before hitting an amplifier.

  • Features:

    • Groundbreaking Direct Tone
    • Maximum input level is a massive +21dBu, making the RNDI-8 capable of handling not only instruments but also professional line-level sources like interfaces and drum machines
    • Rugged Solid Steel Frame
    • The RNDI-8 performs with immense consistency across a wide variety of sources due to its 2M Ohm discrete FET input and huge headroom, providing superb sound for guitars, synths, basses, acoustic instruments, keyboards, and even professional line level devices.
    • The low impedance transformer coupled output is capable of driving long lines with unrivaled high frequency performance.
    • 1/4" THRU Outputs
    • Pin 1 Isolate switches are provided on the rear panel to help fix any problematic grounding, as well as Ground Lift switches on the front panel to isolate each channel's circuit ground from chassis ground.
