Here is a good example of what over compressing drums sounds like.

Beautiful setup and performance but you can hear the compression attack and release is set to high.

I'm a newbie in the sound field. I already got 2 Behringer devices. A composer pro-xl MDX2600 and A multicom PRO-XL MDX4600. I want to setup both of them as a "voice over compression" or Ducking but I do really have not idea how to do it. I though the device user manual shows how to do that but Behringer devices manual only states just a few words about it.

I always read about the great recordings you should listen to, to hear the best mastering jobs. Without being overly critical what are some recordings I should listen to to hear over compression, over limiting, etc. You don't have to step on toes here it's just important thing to know. :D
