What is a Microphone? Microphones are a type of transducer: a device which converts energy from one form to another

Two general types of mics Dynamic mics 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

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

Mic Types HandheldShotgun Lavaliere (Lav) PZM (Pressure Zone Mic)

PICKUP PATTERNS/DIRECTIONALITY Omnidirectional - Picks up 360-degrees

PICKUP PATTERNS/DIRECTIONALITY Cardioid - Picks up in heart-shaped pattern

PICKUP PATTERNS/DIRECTIONALITY Unidirectional (or Hypercardioid) - Picks up in forward/shotgun-type pattern

PICKUP PATTERNS/DIRECTIONALITY Bi-directional - Picks up in figure-8 pattern/equally both sides

MIC CONNECTIONS XLR - Three-pin

MIC CONNECTIONS 1/4” - Also called “Headphone”

MIC CONNECTIONS 1/8” - Also called “Mini”
