Aggressive character compressor with its own unique sonic signature The 4000 B Dynamics (B-DYN) 500 series module takes the dynamics processor found in the channel strip of the SL 4000 B console and puts it into 500 Series format. Released in 1976, the SL 4000 B was the first commercially available console from Solid State Logic and famously used in "The Stone Room" at Virgin's Townhouse Studio (London), Le Studio (Montreal) and Record Plant (LA). It was responsible for countless iconic records, including Phil Collins' "In the Air Tonight" and Peter Gabriel's "Intruder," both of which feature characterful compression on drums and vocals. The B-DYN allows you to add heavily colored, grabby, saturated compression from one of the rarest studio consoles ever made to your production toolkit.
