Rupert Neve Designs Shelford 5051
The Rupert Neve Designs 5051 is a combination of a three band inductor EQ and the compressor found in the Portico II compressor. Utilising a fully-discrete, class-A signal path and high performance input and output transformers, the 5051 delivers the performance and musicality expected from a Rupert Neve design.
The EQ on the 5051 evokes sonic similarities with some of Rupert’s classic EQs, using a custom tapped inductor with selected capacitors to form the mid range equalizer band, and the shelf curves are based on Rupert’s vintage modules, including very similar frequency choices. Each EQ section also uses low feedback class-A discrete electronics to prevent low level artifacts and harshness from detracting from the tonal shaping. The EQ, however, is a modern design with advantages offered by techniques that were not possible 35 years ago along with improvements in electronic components currently available, and should not be considered a clone. Let’s just say it has heritage.
The 5051 Compressor also features a discrete class A signal path proven used in the Portico Series, with individually controllable threshold, attack, release, makeup gain, ratio, side chain HPF, Feed-Forward / Feed-back selection and Peak/RMS detection modes. With the compressor inactive, the 5051 may be used as a transformer-coupled, high-performance line amplifier, and two 5051′s may be linked for stereo operation as well.
The 5051 is intended for 5088 consoles or 5285 vertical frames. There are two +/- 24V power supply options; The 5-way supply is designed to sit in the bottom of a rack, and the 25-way supply is a 2U enclosure. The external +/- 24V supply provides exceptionally clean power, and reduces heat build-up within modules associated with DC-DC up-conversion.
