My school is putting on the musical Joseph this year and I am the head of sound again this year. I was wondering what your opinion was on the best location to put the lapel mic. Last year we attached them to their face using band aids but with them sweating and the make up they didn't always stay on. A friend went in the behind the emerald curtain tour and said that theres are in there hair how would I do that? We are using Shure WL93-6T and we need about 18 of them. Plus we have to buy 2 more belt packs and receivers (about $1,400 each) we can't afford anything more.
