There is another type with a wheel with ridges along the stand part. Then you raise the height of the top to the height you want, then retighten that lock. When you walk with a mike, you might give the mike cord a move like cracking a whip to seeing how far you can walk. Face the mike when talking or they'll miss some of your words. Make sure you're close enough to the mike.
Tension hurts comedy.
If you need to be louder , aim the mike directly at your mouth. If you're too loud , pull the mike away a few inches. If it's not on, TURN IT ON with the little switch on the side. Or you might take your hand off the wire screen on the mike. If that doesn't work, turn off the mike and talk loudly.
