About Rupert Neve Designs Shelford Diode Bridge

Punch, color, weight, and tone. Two channels of iconic diode bridge compression - straight from the Shelford Channel.

What is diode bridge compression?
Where the VCA compressor found in the Master Buss Processor provides unmatched clarity, the weighty, harmonically rich tonality of diode bridge compression can be essential in pushing key sources like vocals, electric guitars, bass and drums to the forefront of a mix.

By understanding the limitations of vintage units like the legendary 2254 & 33609, painstaking effort was taken to reproduce the unique tone of these classics while improving the noise floor & accuracy, expanding inflexible time constants, adding full wave sidechain detection for improved dynamic response, and widening the range of threshold and ratio controls.

Delivering the powerful sound of these iconic designs with enhanced flexibility for the modern age, the Shelford Diode Bridge Compressor is a dynamic tool equipped to make a bold statement on virtually any mix or track.

Features

Classic Diode Bridge Tone
Capture the punchy, larger-than-life tone used on countless hit records for the last 50 years.

Advanced Timing Controls
Custom-shape your compression envelope with the unified timing control, which enables a much wider range of responses than vintage units or clones.

Custom Transformers and Class-A Line Amplifiers
Vintage warmth meets the improved headroom and precision of Rupert Neve's updated transformer-coupled line stages.

31-Position Detented Controls
Accurately recall and match your settings with precision and speed.

Built-In Parallel Compression
Internal blend control enables you to subtly dial in more dramatic compression settings for color as desired.

Full-Wave Sidechain Detection
Enhanced from the vintage units' half-wave design, the updated sidechain detector provides substantially more accuracy.

Stereo Linking
Run your compressors in either dual mono or stereo configurations.

Internal Universal Power Supply
EIC connection for world-wide AC power from 90-240V embedded in the 1U rack-mountable chassis.
