The Rupert Neve Designs 5254 is a Dual Diode Bridge Compressor
Two channels of iconic diode bridge compression, thoughtfully improved and refined for modern tracking, mixing and mastering.
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.
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.
