With a Rupert Neve-designed transformer and a class-A biased discrete FET amplifier, the RNDI elegantly balances any instrument signal - whether straight from a bass guitar or from a screaming 100w amp.

RNDI's unique response delivers a powerful and vibrant direct sound capable of reproducing the full harmonic depth of basses, guitars, acoustic instruments, and professional line level sources. With portable, powerful, larger-than-life tone for your instrument and amplifier signals, the RNDI is truly the first standalone DI worthy of the Rupert Neve name.


• Groundbreaking Direct Tone - where class-A, discrete amplifiers meet Rupert's custom transformers.

• 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 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. 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 - 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 switch on the back helps fix any problematic grounding.

• Phantom Powered.

I bought this on sale and was blown away. I read the reviews and wondered how you could get that excited over a DI. I run my sansamp BDDI into it and get the best bass sound I've ever recorded. Great unit you'll always keep. Sounds awesome on my Martin acoustic as well.
