Solid State Logic (SSL)
Solid State Logic B-DYN 611B
Best dynamics processor for producers seeking aggressive, vintage console character.
The Solid State Logic B-DYN 611B is a 500 Series module that faithfully recreates the aggressive character compressor found in the legendary SL 4000 B console. This module brings the unique sonic signature of one of SSL's rarest consoles to your modern production toolkit. It features a VCA feedback design, similar to the SSL Bus Compressor, offering distinctively colored and saturated compression. The B-DYN includes both Compressor/Limiter and Gate/Expander sections, with fixed ratios, versatile release times including an 'Auto' mode, and a sidechain high-pass filter for enhanced control.

Know before you buy
While both share a VCA feedback design, the B-DYN 611B is based on the SL 4000 B console dynamics. It offers a more aggressive, 'grabby' character compared to the cleaner, more transparent response of the modern Bus Compressor.
Yes, the B-DYN 611B features a Stereo Link mode, allowing you to link two modules for cohesive stereo compression and gating when working with stereo sources.
The 'DS' setting stands for De-Esser. It engages a sidechain high-pass filter that helps the compressor focus on high-frequency content, making it effective for taming sibilance or harsh transients.
No, the sidechain high-pass filter is selectable. It operates at 185 Hz with a 6dB/Oct slope, which is useful for preventing low-frequency signals from triggering unwanted pumping effects.
Because of its peak-sensing feedback design, this module excels on sources that need punch and attitude, such as drum rooms, parallel compression buses, or electric guitars that need to sit firmly in a dense mix.
The 'Auto' release is program-dependent, meaning it adjusts its timing based on the incoming signal. It is highly versatile and generally works well for smoothing out vocals or glueing together a mix bus without audible artifacts.
