The Rupert Neve Designs OptoFET Dual Stage Compressor is a groundbreaking analog dynamics processor that combines two distinctly voiced compressors - an all-new ultra-fast FET design and a refined optical compressor - into a single, immensely flexible 1U rack unit.
Designed for engineers who want total creative control over dynamics and tone, the OptoFET can operate as a serial dual-stage compressor or as a true dual-band processor, opening up entirely new approaches to compression, tone shaping, and harmonic enhancement. From transparent control to extreme envelope sculpting, the OptoFET is built to inspire experimentation at every stage of production. In Dual Stage mode, the FET and OPTO compressors run in series, allowing you to stack fast transient control with smooth, musical leveling—an industry-proven technique now made effortless. In Dual Band mode, each compressor is assigned to either the low or high frequency band, with a continuously variable crossover from 50 Hz to 500 Hz for precise frequency-dependent dynamics. Each compressor section features fully variable attack, release, threshold, make-up gain, and parallel blend controls, plus side-chain high-pass filters and unique harmonic modes: GRIT for aggressive upper-harmonic saturation in the FET stage, and BLOOM for warm, low-order harmonic enhancement in the OPTO stage. With global input/output trim, order flip, and mastering-grade 31-position detented controls throughout, the OptoFET delivers unmatched precision, flexibility, and unmistakable Rupert Neve Designs character.
