When we first talked to them, we heard about how many systems they install and how the equipment was economically priced. We have since discovered that what they sold us was not really the right equipment. It is difficult to get service when we have a problem. I believe they sold us more than we needed and were unable to adjust the equipment properly. We have called in another company that has corrected their mistakes, removed unneeded equipment and properly adjusted what we have. I don't want to ever go back to Gattis Professional Audio for anything other than something like batteries or supplies.
