Quiz 5 Flashcards
transducer
which is a device that converts energy from one form into another
Microphones are usually classified by two key characteristics
the way in which they convert sound into electrical current, and their pickup pattern
The dynamic microphone
one way in which sound is converted into electricity
frequency response
the accurate reproduction of both high and low frequencies
The main disadvantage of the dynamic microphone is that
it has difficulty reproducing certain vocal characteristics
condenser microphone
The other way a microphone changes sound into electricity is to use an electronic component for transduction
phantom power
small internal power supplies
pickup pattern.
direction in which they are most sensitive to sound
on-axis.
Sound picked up at the front of the microphone, or at 0 degrees, is said to be
off-axis
Sound picked up from the microphone’s side is 90 degrees
omnidirectional microphone
picks up sound in all directions and commonly used outside the studio when the ambience of the location needs to be picked up along with a person’s voice
cardioid microphone
picks up sound mainly from one direction – the front of the microphone
unidirectional microphones or cardioid
They continue to offer great rejection of sound from the sides, but each microphone also picks up a narrower scope of on-axis sound.
bidirectional microphone
which picks up sound from the front and rear of the microphone
out of phase
when two or more microphones receiving the same sound signal are fed into the same mixer, the combined signal becomes electronically
X-Y miking
the placement of two cardioid microphones, facing left and right like crossed swords, forming an X- and Y-axis
mid-side miking
microphones arranged in an upside-down “T” pattern
A microphone capsule at one end of a tube (or barrel) is “aimed” like a gun toward the sound source
A parabolic microphone is a type of microphone that is used primarily for field and sports productions. A parabolic microphone employs either a wireless or wired cardioid or omnidirectional microphone, which can either be permanently attached or switched
windscreens
prevent popping, but they also help keep dust out of the internal elements of the microphone and can provide some cushioning if the microphone is accidentally dropped
pop filter
is attached to the microphone stand and positioned in front of the microphone, rather than placed on the microphone itself
A-B miking
which splits a pair of omnidirectional or cardioid microphones to the left and right of center about 3 to 10 feet apart
