Please don't eat the mic!• The more loud, the more distance needed• Pull away the mic on high, loud notes
The location of mic• Minimum distance: under bottom lip• Advantage: avoid the popping effect by some certain consonants (b; p; t)
Don't cup hands over the head of the mic• Muffle the voice
Let engineers control the switch of mic• Don't use the switch on the mic even there is one
Professional mic switch design• Boom sound• Communicate with your engineer, when to...• Trust your engineer
