The Shelford Series



50 years ago, in a converted rectory in Little Shelford, England, Mr. Rupert Neve crafted a series of preamplifier and EQ designs that revolutionized the sound of recorded music. Now residing in Wimberley, Texas, Rupert and his team of engineers have painstakingly combined the very best of these classics with contemporary concepts and components to create the high-voltage Shelford Series of modules.

The Topologies

The heart of the Shelford Series lies within their class-A, discrete, +/- 24V topologies, built around custom-wound transformers and inductors. Rupert carefully engineered these topologies to emulate the renowned 80 Series channel modules crafted during his time in Shelford (1073, 1064, 1081, etc.), and the resulting Shelford Series designs capture the power and soul of his classics, without the compromises of the past.

The EQ section is particularly inspired by Rupert’s previous works, featuring a 3-Band EQ based on the highlights of the classic modules. The low frequency band is primarily based on the 1064, which is renowned for its creamy, resonant bass. Unlike the 1064 however, the LF band can be used as either a shelf or a peak filter, adding punch, dimension, and immense control to your low end. The Shelford EQ’s inductor midrange band is based on Rupert’s prized 1073 EQ, which is ideal for sweetening vocals and instruments while bringing them forward in a mix. The 5052’s high frequency band is a hybrid vintage / modern design, blending inductor circuitry from the 1073 with capacitor-based topologies to deliver vintage tones with enhanced control.

With fifty years and two continents’ worth of evolution, the Shelford Series delivers classic sound in a genuine 21st-century Rupert Neve design.

Aside from being the high-voltage preamplifier and processing complements to the 5088 console, the 5051 and 5052 may also be fitted into any of two available vertical racks for stand-alone use: new 2-way and the 9-way vertical rack, which fits within a standard 6U, 19″ rack.



The modules require +/- 24V on 4-pin connectors from our external DC power supplies . There are currently two options available: the RND 5-way brick supply, and the RND 25-way 2U rack-mount supply.

The Modules of the Shelford Series are:

The 5051: Inductor EQ / Compressor 5051-slight-angle

The 5052: Mic Pre / Inductor EQ
5052-slight-angle
