Since the early 1970s, Rupert Neve’s early diode bridge compressors have been revered for the punch &
glue they bring to drums, instruments, and the mix buss – but these desirable characteristics were
unfortunately accompanied by inflexible controls and fairly limited versatility. Rupert Neve Designs
created the 5254 Dual Diode Bridge Compressor to capture the soul of these coveted compressors while
providing modern updates including advanced timing control, significantly lower noise, fully stepped
controls throughout, higher voltage power rails, and internal parallel processing capabilities.
