Microphones
Dynamic Microphones
Changes in air pressure move the diaphragm, which moves a coil of wire attached to the back of the diaphragm. This coil surrounds a magnet, and as it moves, it creates an electrical signal in the magnetic field.
Negatives:
-
Limited high frequency response
-
Low sensitivity
-
Often large
Positives:
-
Robust and good for live use
-
Can withstand high volumes
-
Does not require phantom power
Uses:
-
kick/snare drums
-
Live vocals
-
Guitar amps
-
Some brass
Condenser Microphones
Changes in air pressure move a large plate, which acts like a diaphragm. A second, charged plate, is directly behind the 1st plate, and together they form a capacitor. As the diaphragm vibrates, the distance between the plates changes, which generates an electrical signal.
Negatives:
-
Fragile, expensive
-
Need phantom power
-
Can peak easily
Positives:
-
Good for studio use
-
Can be very small
-
Can capture high frequency very well.
Uses:
-
Vocals
-
Acoustic guitar and orchestras
-
Piano
-
Drum overheads
Ribbon Microphones
Changes in air pressure move a metallic ribbon that is suspended in a magnetic field. This generates a voltage that is proportional to the movement of the ribbon.
Negatives:
-
Extremely fragile
-
Very…
