Microphone design an dconstruction
1. Can't tell by looking
2. dynamic mics (Loudspeaker in reverse
Uses electromagnetic induction. Causes movement in cone)
3. Capacitor mics

Condensor (capacitor mics) require power supply, onboard battery)

Microphone powering

1. All capacitor mics require a power supply
2. Some use onboard batteries
3. Others use 'phantom powering'

Why use different between dynamic, condenser?
Dynamic: Rugged, not quick responder. Mid, bass. Not thin, transient sound.
Condensor Thin foil, better transient response. picks up SSss

Capacitor mics in general.
Condensor, rock n rolla

1.5 v as well

Used on lapel mics
