500-Series 4KB Dynamics

SSL B-DYN 500 Series Module | Vintage Compressor, Limiter, Expander for Iconic SSL Sound

The SSL B-DYN 500 Series module brings the powerful dynamics control of the SSL 4000 B-Series channel strip into the 500 format. Featuring both a compressor/limiter and expander/gate, this module is designed to faithfully replicate the unique circuitry and key components that defined the iconic SSL B-Series sound.

Unlike other SSL dynamics modules (such as the 4000 E-series or 9000 series), the 4000 B-Series console channel strip used a distinctive design closer to the topology of the SSL Bus Compressor, offering more flexibility and character in the dynamics section. The compressor offers three fixed ratios (2:1, 4:1, and 10:1) with an additional ‘ds’ mode, giving you greater control over your compression.

Utilizing modern components while staying true to the original SSL 4000 B-Series circuit design, the B-DYN module captures the same tone and response that made the SSL 4000 B console a staple in legendary studios like Virgin’s Townhouse Studio (London), Le Studio (Montreal), and Record Plant (LA). It’s perfect for producers seeking the sought-after sound of 80s classics.

The B-DYN module delivers the same grabby, saturated compression that made the original console famous. Perfect for drums, vocals, and mix processing, it brings rich, characterful analogue warmth to any production. Designed for 500 series racks, it’s an essential tool for producers and engineers looking to capture the sought-after vintage SSL tone.
