Rupert Neve Designs RNDI-8 8-Channel Active Transformer Direct Box

The Rupert Neve Designs RNDI-8 is an eight-channel active transformer direct interface. An expansion of the best-selling RNDI Active Transformer Direct Interface, the RNDI-8 is built with the same iconic transformer-infused sound as the original, with added convenience and flexibility in a 1RU format.

DISCRETE FET PLUS TRANSFORMER

The RNDI-8 features Class A discrete FET amplifiers and custom transformers for rich, warm sound, plus per-channel ground lifts and -10 dB pads for added control. Its ultra-high headroom ensures even the hottest inputs will be reproduced naturally and musically. With best-in-class low impedance output, users can run longer cabling without signal degradation, and the RNDI-8’s vibrant tone will make the sound of your other DI’s feel brittle and lifeless in comparison.

THE ULTIMATE STUDIO DI UNIT

With eight channels of direct input, the RNDI-8 makes it easy to patch multiple sources into one place, or to capture direct splits during tracking without compromise. With convenient routing options and robust build quality, you can rely on the RNDI-8 to handle even the most demanding sessions. Whether you're recording your favorite bass, synths, guitars, or submixers, the RNDI-8 imparts a vibrant and natural tone to each source.

Designed for ease of use in both onstage rigs as well as control room front ends, the RNDI-8 is the ultimate DI for any professional audio setup. It allows for patching between instrument and amp, as well as amp and cabinet, ensuring even the output stage’s tone is reproduced beautifully. Its options also enable users to send signals out for “re-preamping” during the mix stage, adding pleasant saturation and euphonic harmonics.

TWO DISTINCT GROUND LIFT OPTIONS

Most direct interfaces include a ground lift switch at the output, and the RNDI-8 includes this standard DI ‘lifting’ option via eight individual ‘Pin 1 Isolate’ switches on the rear panel. Engaging this button will usually eliminate common sources of hum in the signal path. However, the RNDI-8 also includes eight ground lift buttons on the front panel which separate each channel’s circuit ground from the chassis ground, providing another helpful option to detect and eliminate unwanted ground hum.

FEATURES:

• Class A, discrete amplifiers meet Rupert’s custom transformers for groundbreaking direct tone
• Maximum input level is a massive +21 dBu (+31 dBU with -10 dB pad engaged) making the RNDI-8 capable of handling not only instruments but also professional line-level sources like interfaces, drum machines, and even the highest-output DJ mixers
• Rugged solid steel 1U 19" rack-mount chassis featuring an industrial-grade powder coating and is built to withstand the severe stresses of life on the road
• Included bolt-on rack ears are reversible for multiple mounting options
• 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
• Low impedance transformer coupled output is capable of driving long lines with unrivaled high frequency performance
• 1/4" THRU outputs can be used to feed amplifier inputs for reinforcement
• 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
• Each of the RNDI-8’s eight channels is powered by standard 48V phantom power, indicated by blue LEDs on the front panel, one per channel
