2-channel Dual-path A/D Converter with Class A Transformer-less and Transformer-coupled Drive Paths and Active Compound Release Analog Limiter.
อุปกรณ์แปลงสัญญาน A/D Converter & Limiter Rupert Neve Designs Portico II MBC, Dual-Mono or Linked-Stereo Operation, 24-Bit / 192 kHz Reference A-D Converter, Selectable Analog Drive Paths, Active Compound Release Analog Limiting
Rupert Neve Designs’ Master Bus Converter (MBC) sets a new standard for reference-grade 24-bit/192kHz A/D conversion technology. It also incorporates RND’s latest Active Compound Release Analog Limiter, which lets you drive hotter levels with fewer artifacts than plug-ins and ensure clip safety for tracking or broadcast.
Indispensable for tracking, mixing, and mastering, the 2-channel Master Bus Converter incorporates proprietary Rupert Neve analog drive circuitry that lets you choose whether the converter is fed by a Class A transformer-less path for unprecedented transparency or by custom inter-stage audio transformers with variable Silk Texture for a wide range of tonal color.
Equipped with precision clocking for vanishingly low jitter and phase noise, the MBC makes a perfect master clock, and, of course, can be synced to another source.
With its state-of-the-art conversion and gorgeously musical limiter, Rupert Neve Designs’ MBC is an ideal choice for capturing your analog signals with unerring accuracy and stunning 3-dimensional detail.
