I have another problem with the same building, same system. I have a building with meeting rooms of various sizes and I need to link some of them together. The main problem area is the two main rooms are about 200ft apart. The sound board is 2 1/2 up in one room. I need to get signal from one to the other, in essense simulcasting programs. It has been suggested that I use cat5 for the run. Is this OK at that distance or should it be line level on a balanced cable. I am basically a light guy that gets thrown in on these projects because my bosses think I know way more than I do. I keep telling them this isn't so but I keep pulling the jobs off. Thanks for any help you guys can give me.
