I'm going to go out on a limb here. PCCs are useless in most applications in
theatre. Need a tap mic they are great, other then that I try and never use them. Depending on
stage width and depth several shotgun, hyper or even
cardioid mics can give acceptable to good results. It does, however, require very active mixing. Only have the ones you need at any given time, much like
line by
line with wireless. I have mixed musicals with 10-12 cast members with 4
cardioid mics and one LDC mic on a 4 piece band and been fine. Admittedly it was outdoors so that helps, but the rain site we used on a couple of occasions was a tent with walls and it worked in there too. The tent held 275 or so, outside we had 4-500 depending on which of our two spaces we were in. I have also successfully used similiar techniques in my other jobs 414 seat
house, but that tends to be for straight plays. The down side to this is that you will need to convince the director that seeing a mic on a
desk stand is better then not hearing the show. Is it the perfect solution no, a wireless on everyone is far better. Does it work for every show, I don't know, but it has worked for me so much better then PCCs that the only time in the last 8 years I've used a
PCC is in a piano in a pinch.
