The dynamics section of the SL 4000 B console channel strip was unlike any SSL channel dynamics module that followed: it used the fader VCA as its gain element rather than a dedicated VCA, in a design similar to the topology of the SSL Bus Compressor. B-DYN inherits this VCA feedback design, offering coloured compression with its own unique sonic signature, very different from the later E and 9000 Series, and an Auto release with a programme-dependent release time as found on the Bus Compressor.\u003c\/p\u003e\n\u003ctable style=\"border-collapse:collapse;margin:6px 0 18px;width:100%;max-width:100%;table-layout:fixed;\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:12px 8px;text-align:left;border:1px solid #DDE2E8;vertical-align:top;word-break:normal;overflow-wrap:break-word;width:55%;color:#5a6170;font-size:13px;text-transform:uppercase;letter-spacing:.05em;\"\u003eFixed ratios plus DS mode\u003c\/td\u003e\n\u003ctd style=\"padding:12px 8px;text-align:left;border:1px solid #DDE2E8;vertical-align:top;word-break:normal;overflow-wrap:break-word;font-weight:bold;color:#006d77;font-size:17px;\"\u003e2 \/ 4 \/ 10:1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:12px 8px;text-align:left;border:1px solid #DDE2E8;vertical-align:top;word-break:normal;overflow-wrap:break-word;width:55%;color:#5a6170;font-size:13px;text-transform:uppercase;letter-spacing:.05em;\"\u003eProgramme‑dependent release\u003c\/td\u003e\n\u003ctd style=\"padding:12px 8px;text-align:left;border:1px solid #DDE2E8;vertical-align:top;word-break:normal;overflow-wrap:break-word;font-weight:bold;color:#006d77;font-size:17px;\"\u003eAuto\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:12px 8px;text-align:left;border:1px solid #DDE2E8;vertical-align:top;word-break:normal;overflow-wrap:break-word;width:55%;color:#5a6170;font-size:13px;text-transform:uppercase;letter-spacing:.05em;\"\u003eGate or expander\u003c\/td\u003e\n\u003ctd style=\"padding:12px 8px;text-align:left;border:1px solid #DDE2E8;vertical-align:top;word-break:normal;overflow-wrap:break-word;font-weight:bold;color:#006d77;font-size:17px;\"\u003e20:1 \/ 2:1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:12px 8px;text-align:left;border:1px solid #DDE2E8;vertical-align:top;word-break:normal;overflow-wrap:break-word;width:55%;color:#5a6170;font-size:13px;text-transform:uppercase;letter-spacing:.05em;\"\u003eStereo pair mode\u003c\/td\u003e\n\u003ctd style=\"padding:12px 8px;text-align:left;border:1px solid #DDE2E8;vertical-align:top;word-break:normal;overflow-wrap:break-word;font-weight:bold;color:#006d77;font-size:17px;\"\u003eLINK\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch3 style=\"font-size:17px;font-weight:700;color:#0D1B3E;text-transform:uppercase;letter-spacing:.06em;margin:30px 0 12px;padding:0 0 7px;border-bottom:2px solid #006D77;\"\u003eKey features\u003c\/h3\u003e\n\u003cul style=\"margin:0 0 14px;padding-left:20px;\"\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003e\n\u003cstrong\u003eAuthentic recreation\u003c\/strong\u003e of the SL 4000 B console dynamics processing\u003c\/li\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003eDesign based on the SSL Bus Compressor\u003c\/li\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003e\u003cstrong\u003eCompressor \/ limiter and gate \/ expander\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003eFeedback design with peak sensing for an aggressive 'grabby' character\u003c\/li\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003eFixed compression ratios 2:1, 4:1 and 10:1 with an additional \u003cstrong\u003eDS (de-esser) mode\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003eFixed release times DS, 0.2, 0.4, 0.8, 1.6 s and the renowned \u003cstrong\u003eAuto\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003eAuto make-up gain\u003c\/li\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003eSide-chain high-pass filter\u003c\/li\u003e\n\u003cli style=\"margin:0 0 6px;\"\u003eStereo LINK mode\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"font-size:17px;font-weight:700;color:#0D1B3E;text-transform:uppercase;letter-spacing:.06em;margin:30px 0 12px;padding:0 0 7px;border-bottom:2px solid #006D77;\"\u003eCompressor \/ limiter\u003c\/h3\u003e\n\u003cp style=\"margin:0 0 12px;\"\u003eRATIO offers stepped ratios of 2:1, 4:1, 10:1 and DS; OUT bypasses the compressor. THRESH (+10 to -20 dB) sets the level above which compression starts and also provides automatic make-up gain; its linearity has been slightly improved over the original channel strip control to help tuning with the smaller 500-series knobs. A 6 dB\/octave 185 Hz high-pass filter in the side chain helps reduce bass pumping. RELEASE is switched between 0.2 and 1.6 s with DS and AUTO options, and the attack is about 30 ms.\u003c\/p\u003e\n\u003ch3 style=\"font-size:17px;font-weight:700;color:#0D1B3E;text-transform:uppercase;letter-spacing:.06em;margin:30px 0 12px;padding:0 0 7px;border-bottom:2px solid #006D77;\"\u003eDe-esser (DS) mode\u003c\/h3\u003e\n\u003cp style=\"margin:0 0 12px;\"\u003eWith RATIO and RELEASE set to DS, the module is optimised for reducing sibilance: a 10:1 ratio with the side-chain signal filtered at about 7 kHz gives broadband compression triggered by sibilance. The DS release varies with the signal between 30 and 50 ms, much faster than usual for an SSL dynamics section, and the attack drops to 2 ms. The two DS settings work independently, so the fast DS time constants can be used without the DS ratio for aggressive compression.\u003c\/p\u003e\n\u003ch3 style=\"font-size:17px;font-weight:700;color:#0D1B3E;text-transform:uppercase;letter-spacing:.06em;margin:30px 0 12px;padding:0 0 7px;border-bottom:2px solid #006D77;\"\u003eGate \/ expander\u003c\/h3\u003e\n\u003cp style=\"margin:0 0 12px;\"\u003eThe gate \/ expander acts as a 20:1 gate, or as a 2:1 expander with a gentle curve when EXP is pressed. RANGE sets the maximum gain reduction (OUT bypasses it), THRESH the level above which it opens, and RELEASE (0.1 to 1.6 s) how long the signal stays audible after it closes. Attack is a fast 0.2 ms.\u003c\/p\u003e\n\u003ch3 style=\"font-size:17px;font-weight:700;color:#0D1B3E;text-transform:uppercase;letter-spacing:.06em;margin:30px 0 12px;padding:0 0 7px;border-bottom:2px solid #006D77;\"\u003eMetering and stereo LINK\u003c\/h3\u003e\n\u003cp style=\"margin:0 0 12px;\"\u003eTwo LED columns show compressor and gate activity, and IN switches the whole module in or out.
