It's amazing I will have everything set and a boom is adjusted so they
can direct the end of the stand straight to there mouth so to speak
(no excuses). I even tell the stage managers to make certain that the
mic is directly placed in front of there mouth's for best desired
audio placement and the first thing the lecturer does is tilt it down
below there mouth or to the right. AHHHHH!!!!!
Then everyone is looking at me to turn it up, turn it up! I do and I
start to hear that ringgggg and oh be; but mind you I have not fed
back in many many months just that ring and feedback comming soon.

Go up and adjust the mike properly. If they can't point it at their
mouth properly, go up and point it at their mouth for them. It helps
if you have a stage ninja to go up and do it for you.

I once had a Sennheiser 441 on a podium, about two feet away from where
the speaker's mouth should be. At that distance away, the speaker does
not need to think about the mike, and with the 441 you can pull it that
far back and be happy. I had the level adjusted to be just perfect
for a person sitting in front of the podium.

So, an author who shall remain nameless gets up on stage, bends down
to the mike, and says "IS this on?" in a loud voice with his mouth right
up against the mike. Two people in the front row fell out of their chairs.
