For our production we usually use 10-15 cordless mics and due to budget they are often shared and there is no way for me to physically manage the mics during the performance so to combat rule number 2 a few years ago I started using a wire label maker and put each vocalists name on the mic and a duplicate label on the mixer-and I tell the vocalists if they walk on stage with a mic without their name on it it will not be on-period. Last year a young vocalist with just a bit of "I'm the talent" attitude grabbed her and her sister's mics at the last second before a full dress rehearsal. As you might guess, when she stepped out for her solo part on a song no mic-signal LEDs on the board told me she had the wrong mic on, so when all eyes came my way I simply said she has the wrong mic on. As she protested and fumbled under her costume for her mic I decided to bring up the mic she had on so rehearsal could continue. Unfortunately, (fortunately ???) it came up just in time for her to announce to all present, "Oh no, I have (sisters name)'s mic on" . Confession must be good for the soul because it never happened again!
For the production I finished last month it was Wizard of Oz and the board was marked as the actors. Dorthy, Scare Crow, Tin Man, Lion, GW, BW, Oz, Oz with power.
Eight mic's had a number on it and the teacher handed the correct number to the student. Then they marched past the sound board to test one at a time. 4 shows went well. 1st grade to 8th grade.
Oz with power, I took the direct out from Oz and jacked into the next channel strip line in, added excess of bass, reverb with delay, and trimmed back the highs. to give the GREAT and POWERFUL OZ Oz Oz oz oz oz .
For the other parts we just used the normal Oz. so blah boring!
