Extra electricity put into mic's, DC electric power to mic's that have active electronic circuitry (48 volts)
New cards
2
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
New cards
3
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
New cards
4
Ribbon Mic
Thin ribbon-like strip of aluminum between two magnets Movement of aluminum between magnets creates variance CANNOT have phantom power
