Master Bus Converter
From Rupert Neve Designs:
Whether you’re tracking, printing mixes, mastering, or feeding a large PA, the Master Bus 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.
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.
