RNDI

Active Transformer Direct Interface

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
