Solid State Logic 611DYN Dynamics Module

Gearank Recommendation

The 611DYN was on our recommended list for Single Channel 500 Series Compressors from December 2020 until December 2021.

Note: This has been superseded by the 611DYN V2.


The SSL 611DYN takes the legendary dynamics section of the famed 4000E console into a 500 series rack format.

The module also includes the gate/expander section that helps clean up your sound sources.

For vocals, the fast attack setting ensures even and smooth compression with no stray transients.

For those who have experienced the real thing on a console or for those who up until now, have only experienced plugin versions, the SSL 611DYN 500 series comp puts analog dynamic processing within reach.
