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 4000 B was the first console ever manufactured by Solid State Logic and was 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’, which feature characterful compression on drums and vocals. The B-DYN module allows users to add heavily coloured, grabby, saturated compression from one of the rarest studio consoles ever made to their production toolkit.
Solid State Logic 500 Series B-Series Dynamics Features:
Its own unique sonic signature
The dynamics Section in the SL 4000 B console channel strip was unlike any other SSL channel dynamics module that followed, using the fader VCA as its gain element, rather than a dedicated VCA. It had a design similar to the topology of the SSL Bus Compressor. This VCA ‘feedback’ design has been inherited by the B-DYN module, offering characterful and coloured compression, with its unique sonic signature - very different from the later E and 9000 Series. These similarities are also evident from B-DYN’s ‘Auto’ release setting, which offers a program-dependent release time as found on the Bus Compressor.
Compressor/Limiter
De-Ess (DS) Mode
By setting COMPRESSOR RATIO and RELEASE controls to ‘DS’, the B-DYN module is optimized to reduce sibilance (De-Essing). The De-Ess ratio is 10:1 with filtered S/C input signal, delivering broadband compression triggered by sibilance typically in vocal sources. The ‘DS’ release automatically varies in response to the processed signal between release rates of 30 & 50 ms. This is a much faster minimum release than expected from an SSL Dynamics section. The Attack time is also reduced to a quick 2 ms, slightly faster than the E-Series Dynamic module on its FAST setting.
