Often imitated but never equaled, the centre section compressor from the 1980's G-Series analogue console is an audio production legend. It is a simple unit with a simple purpose; it makes complete mixes sound bigger, with more power, punch and drive. It brings cohesion and strength to your mix without compromising clarity. To this day it remains a key element of the SSL sound and has featured on countless classic recordings. The availability of the Stereo Bus Compressor in a module for the 500 format makes this essential audio production tool available to users of the popular API 500 format modular rack platform.
