Solid State Logic - 4K B Dynamic 500 Series Module
New analogue flavour, vintage SSL soundCapture the legendary SL 4000 B console compressor sound in the portable 500 Series format with the 4K B Dynamic 500 Series Module by SSL. This module pays homage to the compressor/limiter and gate/expander found in the channel strip of the iconic 80s consoles gracing 'The Stone Room' at Virgin's Townhouse Studio in London, Le Studio in Montreal, and the Record Plant in LA. Now, you can infuse your portable production toolkit with the distinctive, gripping, and saturated compression that was once exclusive to one of the most coveted studio consoles ever crafted.
For those in pursuit of the revered compression tones heard on timeless records like Phil Collins' "In the Air Tonight" and Peter Gabriel's "Intruder," your quest ends here with this faithful recreation.

Its Own Unique Sonic Signature
VCA ‘feedback’ design hasThe 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 own 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.
De-Ess (DS) Mode
optimised for reducing sibilanceBy setting COMPRESSOR RATIO and RELEASE controls to ‘DS’ the B-DYN module is optimised for reducing sibilance (De-Essing). The De-Ess ratio is a 10:1 ratio with filtered S/C input signal, delivering broadband compression triggered by sibilance typically in vocal sources.
The ‘DS’ release is automatically varied in response to the processed signal between release rates of 30 & 50 ms. This is a much faster minimum release than you would normally expect from an SSL Dynamics section. The Attack time is also reduced to a fast 2 ms, slightly faster than the E-Series Dynamic module on its FAST setting)
Compressor/Limiter
RATIO - Stepped compression ratios 2:1, 4:1, 10:1 and ‘ds’. The ‘ds’ setting is a fixed 10:1 with an additional sidechain filter. When ‘out, the compressor is bypassed.
THRESH - Whenever a signal exceeds the level set by this control, the compressor will start to act at the ratio set by the RATIO control. The THRESH’old control also provides automatic make-up gain. A small improvement to the linearity of this control has been made in the module over the original channel strip control. This helps with Threshold tuning using the smaller scale 500 series knobs.
HPF - A 6dB/Oct 185 Hz High Pass Filter in the compressor sidechain to help reduce bass pumping effects.
RELEASE - Switched/fixed release ranges from .2 ms to 1.6 ms with additional ‘DS’ & AUTO release options.
DS - The De-Ess mode changes the attack time from approx. 30 ms to 2 ms.
