Here is the basic information we would need to give you a thorough answer:
1: How many mics
2: How many actors
3: How many changes
You should have a mic
plot. If you don't, make one. This is the magic peice of paper that knows all. It should have one column for each mic, and one row for each scene, then at the intersecions, put in the characters name AND THE ACTORS NAME. too many times some actors forget who they are playing.... I know, odd, but trust me, you can
call out "Bird Number 3" for as long as you like, but calling out "Mary S." will have much better results.
I would be very reluctant to have the cast change there own mics, so many times I have seen cast
drop, pull, bent
etc. $500 capsuals. The only issue you may have getting someone else to change them is the school may say that you have to have a male and female fitter for male and female cast respectively.
In regards to the show itself, a lot of the cast, depending on the way the set is laid out, do actually go off
stage for a few minuits at a time. It depends, as I said before who is being miked.
If you want some more in-depth help, feel free to email me -
