The Rupert Neve Designs Portico 535 is based on the classic circuits of the Neve 2254 compressor, but has significantly reduced inherent noise compared to its historical predecessor thanks to modern circuitry, which delivers a rich and punchy audio response. Versatility and a great sound are capitalized here and become noticeable right from the first test. With the Portico 535, Rupert Neve Designs brings the diode bridge compressor of the Shelford Channel into the API 500 format.
