To swing it to a general, related point about audio...
I often think that some production assistant should be tasked with telling talent at awards shows (and similar) that they don't have to bend down and eat the mic, and that it's possible to just keep standing straight up.
It's so often people who should have the experience to *know* that they don't have to bend down and eat the mic. Pet peeve!
I run into the opposite problem a lot, with people who are not accustomed to using a microphone. For example, if I'm playing at a wedding and part of my job is to have a wireless mic set up for toasts and all that, people will invariably hold the mic at approximately the level of their navels, making it a real struggle to get any kind of perceptible gain before feedback.
I was playing at another event, a private party at a winery hosted by Alfa Romeo for wealthy auto enthusiasts. They used my PA to do a raffle, and the guests were having a hard time hearing the people speaking because they were all holding the SM58 2 feet from their mouths. Then Jay Leno, who has had a lot of practice using handheld mics, got up to finish off the event. You can imagine the difference - I had to back off the gain in a hurry.
(Alluding to that other thread - can I now claim to have worked with Leno? Kidding!)
