Shelford Channel User Guide
Thank you for your purchase of 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 & 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 5051 and 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 when bold statements are required, 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.
Everyone at Rupert Neve Designs hopes that you enjoy using this tool as much as
we have enjoyed designing and building it.
Please take note of the safety concerns and power requirements before using this
product.
