These switches control the sidechain operation of the compressor. Two of them are linked to something called "SC". Now, on the GUI for DensitymkIII you will see three switches on the bottom right. You know set up the compressor where you want it to compress and then route what you want to sidechain with to that as well. You're going to do it pretty much the same way you would with the Fruity Limiter initially. I'll use DensitymkIII as an example of how to set it up. Though sometimes you'll find Fabfilter Pro-C or Bootsie's DensitymkIII. I use Cytomic's The Glue almost every time.
