I am new here and have gotten so many answers from these forums and want to say thanks. I have an odd question. I work at a High School Theatre and have a clearcom system in place(not sure of the base station model right now) I know the belt packs are rs-601's. I have a phantom Mic that hangs above the stage and comes back to the rack straight into a Biamp D60eq 70v amp and then to the two dressing rooms. Somehow we are getting audio from that phantom mic onto the clear com headsets but there is nothing running from the phantom mic onto the back of the base station. My question is it possible to get audio from a 70v system onto the clearcom headsets any other way than the base station? We don't want that phantom mic on our headsets.. it does go away when we turn off the 70v amp but then it also goes away from the dressing rooms where we need it. What is my solution? I hope it is just attached to one of the speakers in the ceiling somewhere because I don't want to crawl around in that space up there a whole lot. Any ideas will help! Thanks!
