The ultimate tool for creating digital signals with the tone, transparency, and power expected from Rupert Neve Designs.

Whether you're tracking, printing mixes, or mastering, the Master Buss Converter is a revelation in quality and functionality of A-D conversion technology. The analog drive circuitry allows the MBC's converter to be fed by either a class-A transformerless path for maximum transparency, or by custom inter-stage audio transformers with variable Silk for a wide variety of tonal enhancements. Coupled with an astonishingly musical limiter, the MBC is always the best choice to capture your analog signals with breathtakingly three-dimensional accuracy.

A Long Time Coming

With over seven decades of analog circuit design experience, Mr. Rupert Neve had never considered a converter worthy of his hallmark until the release of the RMP-D8 Dante-connected microphone preamplifier in 2018. While the RMP was primarily designed as a mic preamp, its adoption by engineers at the highest levels of recording, mastering, and touring as their preferred converter led to the development of the MBC, creating a new standard for PCM conversion quality.

Dual Path Analog Design

As the last link in the analog chain before digitization, converter drive circuitry is critical in determining the imprinted digital sound quality. From the ground up, the MBC was designed for reference performance regardless of genre or desired sonic character, and the key to this lies in the quality… read more and adaptability of the analog drive circuitry.

For a bolder, more powerful imprint, a custom-designed inter-stage transformer with Rupert's acclaimed Silk circuitry can be inserted to recreate the classic tonality of his vintage designs. Uniquely, unlike our audio transformers intended for line-level output, this new transformer is designed to achieve output transformer harmonic content characteristics at a level appropriate for input to the converter itself. With the addition of variable Silk, the engineer is able to precisely dial in the desired amount of harmonic content - with the Red mode highlighting harmonics in the mid and high frequencies, and the Blue mode accentuating harmonics in the low-end. From a subtle transformer tonality without Silk, to significantly more color than vintage modules with the Silk / Texture circuit fully pushed, the selectable transformer path fills your tracks with enhanced dimensionality and power.

When maximum transparency and fidelity is desired, the transformerless path provides extraordinary detail and clarity. While many transformerless circuits suffer from thin tonal balance and a lack of punch, the MBC's Class-A circuitry was painstakingly designed to deliver a beautiful sense of clarity, with vibrant detail at both high and low frequencies. As an additional tonal palette to capture your tracks, the transformerless path is an essential complement to the weighty, classic sound of the transformer path. No matter what sonic character you're seeking, the MBC can provide it at the push of a button.

Compound Active Release Analog Limiter

The challenge here was to design a limiter that could act as both a musical sculpting tool exceeding the quality of available plug-in limiters, while also being able to act as a transparent safety limiter for tracking or live performance & broadcast.
To achieve this, we refined our compound active release topology to enhance both the accuracy and musicality of the limiter response. The resulting limiter achieves both transparency and the capability of pushing the level of tracks or mixes without damage to the integrity of the source.
