SSL B-Series Dynamics Module


The new 4K B DYN 500 Series Module will be released to the public in Summer 2023. If you are interested in finding out more about the 4K B DYN 500 Series Module, click the "FIND OUT MORE" button at the top of the page and leave your details so a member of our sales team can assist you. 

The B-Series Dynamics Module continues the expansion of the SSL 500 Series Modules and comprises of a compressor/limiter and an expander/gate. It is modelled on the original circuit design of the SSL 4000 B-Series channel strip as Installed in the 80s in ‘The Stone Room’ at Virgin’s Townhouse Studio (London), Le Studio (Montreal) and Record Plant (LA).


  • Legendary SSL 4000 B Series Channel Strip circuitry
  • Stepped compression ratios 2:1, 4:1, 10:1 and 'ds'
  • Automatic make-up gain with THRESHOLD control
  • DS setting has fast attack and release time
  • OUT setting takes gate/expander out of the circuit
  • LINK sidechain prevents image shifts with stereo signals
Aggressive character compressor with its own unique sonic signature
The B-Series Dynamics Module features a compressor/limiter with three fixed stepped compression ratios 2:1, 4:1, 10:1, and an additional 'ds' mode. The 'ds' setting is a fixed 10:1 with an additional sidechain filter. The differing topology makes the B-Series Dynamics module a more characterful and colored Dynamics processor than the E-Series. Its gate/expander can act as a 20:1 gate or as a 2:1 expander when the EXP button is pressed. The OUT setting can also take the gate/expander out of the circuit independently of the compressor. The B-Series Dynamics Module's circuitry is based on the legendary original circuit design of the SSL 4000-B Series Channel Strip that gave that iconic 80's sound.
