The DBX 166XL is a dual channel rackmount compressor, with signal gating and limiting functionality. This is actually a pretty slick little compressor that we placed between our mixer and our mains to control the audio level more evenly, and prior to that I was using it as my dedicated bass compressor.
There are so many practical features on and uses for this device, its difficult to list them all; thankfully the user manual is readily available and easy to understand. http://www.dbxpro.com/en-US/products/166xl
