I have a shoot coming we're there are four presenters that are going to podium to make some remarks. I don't want to put a wireless on each one of them or have them trade it off to the next person. So, I want to attach a hand-held microphone to a table top or floor mic stand and have them use this. I have an SM58 but thought it doesn't pick up well unless you are very close to it. I am looking for a good mic that will pick up well even if some of the presenters talk softer than the next. Any recommendations?
