RUP-RNDI

Rupert Neve RNDI Active Transformer Direct Interface

2 IN STOCK

The Rupert Neve RNDI Active Transformer Direct Interface is the product of new custom Rupert Neve-designed transformers and class-A biased, discrete FET amplifiers. The carefully orchestrated union of these two elements is key to the RNDI’s unique response, delivering a powerful and vibrant direct sound capable of reproducing the full harmonic depth of basses, guitars, acoustic instruments, and professional line level sources. 


    • Rupert Neve RNDI PRODUCT FEATURES:

      The Development

      After coming into existence during an experimentation with new transformer designs, the RNDI was fine-tuned over a series of listening tests against the the most popular high-end DIs available. It was in these tests where the RNDI always seemed to add another dimension to the sound and bring the instruments to life. The lows felt richer, deeper and fuller, and the highs had outstanding clarity without any added harshness. Most importantly, the design team noted: "As musicians, the RNDI consistently stood out as the DI we wanted to play through."

      Key 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 2M Ohm discrete FET input and high headroom. You can confidently use the RNDI with basses, guitars, acoustic instruments, keyboards, and even professional 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
