Hello, Would you advise on how to remedy a situation where muting a Shure headset (E6OW5T2SL) suddenly takes down the overall volume level for the whole band & all the singers? This is ONLY so noticeable when listening/ reviewing the YouTube recordings; I don't hear this in the sanctuary. I look forward to hearing from anyone who may have experienced a similar situation/ or knows how I can possibly fix this. FYI: All previously set up 'Mute Grps' were reviewed & no overlaps/ repeats. I've now completely removed all, but issue still remains - Ty.
