Dual Path A-D Converter & Limiter
Rupert Neve Designs MBC Dual-path A/D Converter & Limiter
SELECTABLE ANALOG DRIVE PATHS
The very best of class-A transformer-less and custom transformer-coupled designs at the touch of a button.
TRANSFORMER PATH WITH SILK / TEXTURE
Add weight and punch with a dedicated custom inter-stage transformer before the converter. Silk / Texture allows you to dial in the harmonic content and drive saturation of this signal path.
CLASS-A TRANSFORMER-LESS PATH
Maximizes clarity and transparency of the input signal.
COMPOUND ACTIVE RELEASE LIMITER
Ultra-fast response, useful both for musical sculpting and transparent level control.
SIDE CHAIN HPF
Tighten the response of your limiting with a 12dB / Octave SC HPF sweepable from 20Hz to 250Hz.
24-BIT / 192kHz REFERENCE CONVERSION
Unparalleled analog capture with precision clocking using top-of-the-line chips.
Connect to any of your digital devices with AES, S/PDIF and TOSLINK all simultaneously available.
Maximum accuracy with minimal jitter and phase noise, able to operate as a master clock or sync from another master.
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 interstage 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 and adaptability of the analog drive circuitry.
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 further adapt the sound of the limiter, we’ve added a number of controls to fine-tune its response: The built-in sweepable side chain high-pass filter minimizes the limiter’s reaction to low frequencies to let your bass come through full-force, the class-A line amp stage adds up to 20dB of ultra-clean gain, and the MBC can even be used as a dual mono design (rather than stereo linked) for high-fidelity instrument tracking purposes.
The MBC’s 24-bit/192kHz converters were developed after years of careful listening, and represent a further advancement of the design within the RMP-D8. The precision controlled internal clock’s minimal jitter and phase noise allow the converters to capture the complete performance of your music with a great degree of accuracy – simply put, the MBC creates an uncanny digital representation of your analog signals.
To connect into your interface or digital console, the MBC is equipped with AES, S/PDIF and TOSLINK outputs capable of simultaneous output to multiple destinations. The word clock output allows the MBC to act as high-end master clock for your entire setup, and the word clock input allows external sync to a separate master clock if desired. Finally, to seamlessly integrate the MBC into a multichannel conversion environment, four standard levels from -14dBFS to -20dBFS can be selected to accurately match your other converters. These Reference Level calibration standards are implemented with a superb degree of accuracy via high-precision resistors and relay-controlled stepped attenuation.
