If you had four wireless mikes tuned to the same frequency and all operating
at the same time, they would interfere with each other. What you could do is 
add a pushbutton switch to each in series with the battery. When the person 
wanted to say something he would push the switch and power up the mike.

Otherwiset the concept of using multiple wireless mikes tuned to the same 
frequency is sound.
