"TheS-Typeis a typical VCA compressor well known as the core of the legendary British sound. The heart of the compressor is the THAT chip instead of the now unavailable DBX. The analogue path is balanced with ultra-fast A class op-amps. This is the source of completely transparent sound. A minimal level of noise allows the device to be used in recording classical music, including long range recording.Themain new feature of the S-Type is the Sidechain regulation.This allows the user to select the lowest frequencies which will not be compressed and more precisely control the bass and dynamics of the mix. Overall the S-Type is a very creative device."
