Microphones/Speakers

Phantom Power

Extra electricity put into mic's, DC electric power to mic's that have active electronic circuitry (48 volts)

Dynamic Mic

Has a diaphragm, cylindrical wire coiled magnet
Energy moves back and forth on wire, converting it into pos and neg energy (Alternating Current)
Doesn't need phantom power

condenser microphone

Two plates: backplate and diaphragm
Soundwaves vibrate within the diaphragm
The distance between the back plate and diaphragm impacts the voltage called capacitance
Requires phantom power

Ribbon Mic

Thin ribbon-like strip of aluminum between two magnets
Movement of aluminum between magnets creates variance
CANNOT have phantom power

Cardioid

Heart shaped!
Records in one direction

Omnidirectional

Records from all sides (360)

Bidirectional

Records from two directions

Hyper-cardioid

Records from an extreme distance but only one direction

Moving Coil Speaker

Works like a dynamic mic!

Electrostatic speaker

Works similarly to a condenser mic

Ribbon Speaker

works like a.. you guessed it.... ribbon mic

Active Speaker

Plugs into a wall
Doesn't need amp

Passive Speaker

Requires an amp (needs someone else's energy)
