RNDI-S Stereo Active Transformer Direct Interface

SKU: RND-RNDI-S
MSRP: $599.00
MAP: $599.00

Overview

An expanded two-channel version of our wildly popular RNDI, providing massive tone & headroom for all of your instruments & stereo sources.

The RNDI-S contains custom Rupert Neve-designed output transformers and class-A, discrete FET input stages. This carefully designed combination is the key to the unparalleled performance of the RNDI-S, delivering a powerful and vibrant direct sound that captures the full harmonic depth of basses, guitars, acoustic instruments, pre-recorded material and even consumer devices via the 3.5mm stereo input jack.

With portable, powerful, larger-than-life tone, the RNDI-S is ready to make your stereo or mono direct sources shine.

Signature Sound

The signature sound of the RNDI-S is the result of new Rupert Neve-designed output transformers and class-A, discrete FET input stages. The carefully orchestrated union of these elements is key to the accuracy, tone and response of the RNDI-S.

THE TRANSFORMERS

The custom output transformers provide exceptional isolation while introducing musical harmonics and dimension to the sound. The low impedance, transformer-balanced outputs excel at driving long cable runs, and performance is immensely consistent regardless of the connected equipment. This is very important for both live and studio environments where the audio signal may travel over 100ft before hitting an amplifier.

THE CLASS-A, DISCRETE FET AMPLIFIERS

The class-A, discrete FET input stage in the RNDI-S is powered by 48V phantom, providing a high impedance input of 2.2M Ohms that ensures consistent performance with a wide variety of instruments. The class-A design introduces no crossover distortion to the signal, which can add upper-order odd harmonics that are musically dissonant in nature. With the RNDI-S, the majority of harmonic content is a pleasing combination of 2nd order (octave) and 3rd order (fifth above octave). These musically relevant harmonics, present in subtle amounts, enhance the richness of the original signal and provide a distinctly musical response. And the discrete nature of the RNDI-S design means there are no ICs or digital components that can have negative effects on the tone.

CONTROLS & I/O

2x ¼” INPUTS

  • Hi-Z unbalanced inputs with 2.2M Ohms input impedance.

2x ¼” THRU JACKS

  • Parallel ¼” jacks used to send signal to an amp or speaker.

3.5MM INPUT

  • Stereo unbalanced input with 95 kOhm input impedance. Ch 1 = Tip, Ch 2 = Ring.

INPUT SELECT

  • Selects ¼” Input or 3.5mm Input.

48V POWER LEDS

  • Indicates that +48V phantom power is present for each channel from the connected mic preamp(s). Power must be supplied independently to both channels.

GROUND LIFT

  • Isolates the XLR Pin 1 from the circuit ground for each channel.

OUTPUT

  • Transformer-balanced XLR output. Impedance <40 Ohms. Phantom power to the RNDI-S is supplied through these connections.
