Unlike VCA compressors, which are designed for clarity of tone, the harmonically rich tone of the dual diode bridge compressor produces a wide range of coloration, making it ideal for musical accentuation. Based on the dynamics circuitry developed for the acclaimed Shelford Channel, the 5254 features a custom Rupert Neve Designs transformer and Class-A electronics, and is available in dual mono or stereo operation. While the VCA compressors found in the diode-bridge Portico II Channel and Master Buss Processor deliver unparalleled clarity, the rich, harmonically rich tone of diode bridge compression is essential for bringing important sources like vocals, electric guitar, bass, and drums to the forefront of the mix. The development team revisited all of the vintage unit's topologies to recreate their distinctive tones while improving noise floor and accuracy, extending time constants, adding a full-wave sidechain detector for improved dynamic response, and expanding threshold and ratio controls. The 5254 Dual Diode Bridge Compressor delivers the powerful sound of its iconic design with improved flexibility for modern demands, making it a dynamic tool for making bold statements in virtually any mix or track.
