Thanks again everyone for the replys. I have learned alot. I havent put eyes on the units, but I think the problem is they are not all in the same "bank" as sennheiser calls it or "group" like shure calls it.
I grabbed random freq to maximise the freqs in between each mic. From my reading here and conversations from the other tech, plan is to reset all freq and switch two of the units for G band that are in another venue about 120 ft away from the main room. This will give us 8 A's, 2 G's, and 7 B iems.
