Meta Analysis Overview

Our rating of 92/100 is based on analysis of 10+ sources comprised of online reviews and discussions. Under the Pros and Cons headings below you'll find a condensed analysis of what those owners and users have been saying. Feel free to ask questions or add your thoughts in the comments section.

Note: This has been superseded by the 611DYN V2.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


  • Controls: Ratio, Threshold, Release
  • Input/Output Impedance: Not specified by manufacturer
  • Maximum Input Levels/Output Levels: +28dBu.
  • Attack: Program-Dependent or Fast (0.1ms)
  • Release: 0.1 to 4 sec
  • Ratio: 1:1 to Infinity:1
  • Threshold:-26dB to +4dB


The 611DYN gets praise for its versatility, aside from being a compressor, the expander gets high marks for its ability to give punch to snare drums while reducing bleed. For vocals, the fast attack setting ensures even and smooth compression with no stray transients.


One con was generally directed towards the modularity of the 500 series rather than the product itself. Another claimed that the 611DYN doesn't exactly sound like the console version.


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.

Unfortunately this is no longer available new in stores, however you can see highly rated alternatives in our guide to The Best 500 Series Compressors.
