Just a quick setup question. S5000, DM64, ME. We use a combination of wireless IEM’s set on the St aux outs(singers) and ME units(stationary band members). The problem is the talkback mic is always open going to the ME’s regardless of the talk button position. It seems to work fine going the the ST auxs, how can I configure the talkback to be muted going the the ME’s as well as the Auxs.
