5035 - Overview

A Whole New Vintage
The 5035 Shelford Channel is built around Rupert Neve’s first new transformer-gain, class-A microphone preamplifier in over 40 years, a “best-of-the-classics” inductor EQ section, a tone-packed diode bridge compressor, the power of variable Silk saturation, a new dual-tap transformer output stage, and twice the operating voltage of vintage designs.

Over fifty years in the making, the Shelford Channel is the definitive evolution of the original technologies in Rupert’s classic console modules like the 1073, 1064 & 2254, thoughtfully advanced and refined for the 21st century studio.

The Input Stage and Transformer Gain Mic Pre
Like Rupert’s designs from his time in Little Shelford , the Shelford Channel’s preamplifier uses a directly-coupled transformer input with gain provided by the custom transformer itself – a first in over 40 years for Rupert Neve. This new custom-designed input transformer, along with its careful integration with the surrounding class-A circuitry, is critical to the Channel’s bold and instantly recognizable character.

Conveniently, the Direct Input uses the same topology as the best-selling RNDI Active Transformer Direct Interface, providing astonishing clarity for high-Z instrument signals, with unparalleled low-frequency response and an incredibly smooth high end.

What is Silk?
The Silk & Texture circuit on the Shelford Channel allows you to fine-tune the amount (and type) of harmonic content in the output stage. This means your signal can be adjusted from quite transparent to settings that produce nearly 10x the amount of sonic color as Rupert’s vintage modules – and in two very unique modes. No matter what sound you’re looking for, Silk can help get you there.
