I just bought a Behringer PPA2000BT and I don't understand what this Klark Technik unit is- what is it for, and how do you use it- there is nothing in your manual that I can tell anything about it. It has dials that you turn up and down but that is all- can you email me an attachment to my email of doncdunlap@aol.com. I would hate to have to return the unit because I don't get it- I am technology challenged
