“Creating a Back Pocket Pads, keys, aka support instruments Send all the instruments you want positioned in the Back Space of your mix to this bus/group. Put your desired compressor on the group. (SSL Compressor emulations are an excellent choice). Set Attack .1 - 3ms. Set Release .3 - .6sec. Set Ratio: 2:1. Bring the Threshold down until you have 1 - 2db of gain reduction. Adjust the makeup gain if you feel it’s necessary to restore any lost volume (I often don’t feel the need to if all I’m getting is .5 to 1db of gain reduction).”
