Rupert Neve Designs Shelford Channel

Get Modern Innovations On Classic Sound - The Shelford Channel

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, 1081 and 2254, thoughtfully advanced and refined for the 21st century studio. The Shelford Channel is built around Rupert Neve's first new transformer-gain, class-A microphone preamplifier in over 40 years, the "best-of-the-classics" inductor EQ section from the Shelford 5052, a tone-packed Diode bridge compressor, the analog power of variable Silk saturation, a new dual-tap transformer output stage for maintaining headroom or allowing the full driving of the Channel without clipping standard converters, and twice the operating voltage of vintage designs.

With richly-colored tonal options for making bold statements with your music, and precisely-engineered detented controls for recall, the vintage-inspired Shelford Channel maintains the soul of Rupert's classic designs with new levels of versatility, delivering what can only be described as the combined essence of fifty years of Rupert Neve's designs.

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 circuitry, is critical to the Channel's bold and instantly recognizable character.
