I run sound for my church and we are looking to add delayed speakers midway in our space. I am looking at the iQ series because of the Ultranet connectivity. I am wanting to replace our Main L&R and Subs with iQ's as well. Here are my thoughts: I currently is all 16 Ultranet channels of the PM16 for IEMs. They are connected up stage to my S32. My mixer is the full size x32. I would like to have all my speakers running off of Ultranet also. I have seen some things discussing multiple Ultranet networks. How do I achieve this?
