2U Full width rack mount two channel compressor & limiter with dual mono, stereo and mid-side operation modes featuring ‘Blend’ and variable ‘Silk’ functions.
The Rupert Neve Designs Portico II Master Buss Processor is a creative tool that redefines the boundaries and limitations of traditional 2-channel compression and limiting.
With input and output transformers designed and implemented by Mr. Rupert Neve, the high-voltage 72V topology found in the Master Buss Processor (MBP) will integrate flawlessly with virtually any system. Additionally, the MBP incorporates mastering grade detented pots throughout to fine tune its revolutionary dynamics, tone, and stereo field controls.
The MBP’s two compressor sections allow virtually limitless possibilities in dynamics for either dual mono or stereo sources, with controls for ratio, threshold, attack, release, blend, side chain HPF, limit and make up gain.
The Portico II Master Buss Processor also features an extremely versatile, transparent and musical limiter. Featuring Adaptive Release Technology and using a blend of release time constants, this limiter will simultaneously respond quickly to transient material (such as the “snap” of a snare drum) and slowly to more sluggish signals (such as a bass guitar).
The stereo field editor on the MBP takes traditional M-S techniques to new heights with width, depth and corresponding bandpass filters. The width control enables the user to increase or decrease the width of a stereo image (wide/mono) and adjust the amount of ambience inherent in the recording. The depth control of the MBP adjusts the spatial positioning of elements in the sound stage. Center-panned elements like solo instrument or vocal can be brought forward in a mix, in relation to supporting instruments.
