5254 Dual Diode Bridge Compressor

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.
