Two general types of mics
Dynamic mics
- No power required

Condenser mics
Two general types of mics
Dynamic mics
- No power required
- Magnetic diaphragm acts like a sail – generates electricity via a magnet
- Only react to strong sounds
- Rugged, short range, low sensitivity
Condenser mics
- Don’t create electricity – use charge from battery source
- More sensitive, greater range, much more fragile
