Chapter 3 Flashcards
VU
Measures volume
VU measurements
Measured in decibels and percentages
“In the red”
Audio is too loud/distorted
“In the mud”
Sound is either too quiet/not picking up on mics
Monitor speakers
The speakers are the direct link to your ears
Feedback
A rumbling or whistling noise caused by a sound system
Running a “tight board”
No dead air in the program, closing all gaps
Program and audio bus
Program carriers to transmitter, audition normally carries to a recording device
Cue channel
Monitors the song before you play it on the radio
Microphone
Electro-mechanical devices and are divided into two distinct types, dynamic and electrostatic
Dynamic microphone
It works using magnetic inductance, it has a moving coil . As the sound wave hits the diaphragm and coil of wire, they move back and forth through the magnetic field generates a very low voltage electrical signal. They accurately reproduce a wide frequency range and have a transparent sound, meaning they do not color or change the original sound
Dynamic Microphone Characteristics
Deep, rich quality they add to the announcers voice. This is due to the proximity effect, the closer you move to the face of the microphone, the lower your voice appears to go, taking on a richer brassy quality.
Proximity effect
Occurs when a directional dynamic microphone is placed closer to a sound source like a drum or other instrument rich in bass. No directional dynamic microphones do not exhibit the proximity effect.
Dynamic Microphone Applications
They are very rugged and can withstand a number of different environments. They are excellent to use extensively in radio and in high sound pressure level environments like a stage or rock concerns . Retail prices range from $125-$1,000
Excellent microphones in the $300-$500 range
