Choose from optical compression, VCA compression, or both in series, for unprecedented dynamic control with a mastering-grade signal path
Optical section provides smooth, program dependent leveling, just like a classic audio leveler from the late-’60s
Discrete section gives you the fast, precise sound of a classic VCA compressor
Sidechain frequency filter prevents frequencies below 90Hz from triggering compression for tighter-sounding mixes
