Rupert Neve Designs Portico II Master Buss Converter

Rupert Neve Designs Portico II Master Buss Converter

The Rupert Neve Designs Portico II Master Buss Convertor implements analogue drive circuitry which allows for the convertor to be fed by either a class-A transformer-less path, or by custom inter-stage audio transformers with variable Silk. These options allow you to choose from maximum transparency, or a wide range of tonal enhancements. Whether you're tracking, printing mixes or mastering, the Master Buss Convertor is a revelation in quality and functionality of A_D conversion technology.

Features

Selectable Analog Drive Paths

The very best of class-A transformerless 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 Transformerless Path
Maximizes clarity and transparency of the input signal.

Active Compound Release Analog Limiting
Push your levels further with fewer artefacts than plug-ins, and introduce clip safety for tracking or broadcast.

24-bit/192kHz Reference Conversion
Unparalleled analogue capture with precision clocking using top-of-the-line chips.

Multi-Standard Connectivity
Connect to any of your digital devices with AES, S/PDIF and TOSLINK all simultaneously available.

Precision Clocking
Maximum accuracy with minimal jitter and phase noise, able to operate as a master clock or sync from another master.
