format_quote The RNDI’s signature sound 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. 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.

Speaker and Instrument Mode User Notes
In a speaker feed configuration, the DI is used post-power amplifier to capture the tone of the preamp and power amp. Be sure to switch the RNDI input level to speaker and connect the amplifier and speaker BEFORE turning the amplifier on.

Note: with tube power amps, THE SPEAKER MUST BE CONNECTED to the THRU connection to provide a load for the amplifier. Please read your amplifier’s manual to discern its range of acceptable loads. Solid state amps can generally be run without a speaker connected, although you should always consult your amplifier’s manual to be sure. The RNDI can handle the full amplified output of a 1000W amp, so you can confidently drive the output stages of any amp less than 1000W to get your desired tone.

In an instrument configuration, the DI converts the impedance of the instrument signal, balances the signal (if unbalanced), provides a buffered output stage to send to a separate mic preamp, and optionally sends the THRU connection to the amp input. To get the best performance out of your RNDI, we recommend you use the best available cables and mic preamps, and output the maximum level from your instrument. The instrument connects to the IN jack, and if you want to feed an amplifier, connect the THRU output to your amplifier’s input. The output of the RNDI in both instrument and speaker mode feeds a separate preamp for final gain.

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
