Amps are already off stage in isolation boxes. I am very familiar with IEMs and yes it will take a bit of getting used to. I am leaning towards leaving the vocals in wedges and iems for everyone else.
I am leaning toward installing a roland system for use with a Yamaha m7cl board.
I am wondering if anyone else has this combination or if anyone else is using the Roland m-48 system. We haven't pulled the trigger on the purchase and just looking for pros and cons or any other better...
