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.
