Solid State Logic’s B-Series Dynamics Module packs the dynamics section of the company’s legendary SL 4000 B console channel strip into a convenient 500 Series format. This hearty piece of kit is powerful enough to tackle all of your dynamics needs. Its compressor/limiter boasts three stepped ratios, along with a dedicated sidechain mode, plus automatic makeup gain for fast, easy deployment. You also get adjustable Thresh and Release knobs, with an autorelease setting, plus a built-in highpass filter. The B-Series Dynamics Module’s selectable gate/expander delivers everything from subtle noise filtering to heavy gated-snare sounds with a few knob twists. This must-have 500 Series module also includes a Link sidechain to safeguard against image shift with stereo signals. If you’ve ever wanted ’80s-era SSL-console dynamics for your studio, the Solid State Logic B-Series Dynamics Module captures that iconic sound flawlessly.

The sound that defined the ’80s

The SL 4000 B console defined the sound of the 1980s, having found a home at Le Studio in Montreal, Record Plant in Los Angeles, and — most famously — Townhouse Studio in London, where it spawned a decade’s worth of gated-snare effects. The Solid State Logic B-Series Dynamics Module includes a compressor/limiter and a gate/expander, both of which are modeled on the original circuit design of the SL 4000 B console channel strip, equipping you with dynamics processing that’s more characterful and colored than that of its successors. Many of us here at Sweetwater have fond memories of working on B series boards, and we’ve found that the B-Series Dynamics Module replicates this experience better than any other 500 Series module we’ve used.

Delivers aggressive SSL character

The Solid State Logic B-Series Dynamics Module includes everything you’d expect from an SSL console’s dynamics section. Its compressor/limiter sports three compression ratios: 2:1, 4:1, and 10:1. You also get a DS mode, which employs a fixed 10:1 ratio, along with an additional sidechain filter. The module’s gate/expander can operate as a 20:1 gate or a 2:1 expander with a push of its Exp button. You also get an Out setting that takes the gate/expander out of the circuit entirely without affecting the state of the module’s compressor/limiter.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
