80
Q

Tube microphones are the first to go up and last to come down. Explain.

A

Tubes take awhile before they ‘settle in’ and need to warm up. Tubes are fragile, especially when hot, so they must cool down after the session before moving them.

A

Monitor Insert switch

86
Q

(MP100 Study Guide) What kind of microphone has the best transient response? -what NOT to choose-

A

The answer will NOT be condenser. lol

I think it would be ribbon because the ribbon is so thin, so it takes less air pressure to move it

87
Q

(MP100 Study Guide) Which mic has the best SPL rating?

A

The answer will be a dynamic mic

88
Q

Examples of dynamic mics with high SPL

A

Shure SM-58: 150 dB
Shure SM-7B: 180 dB
Shure Beta 52: 174 dB
Sennheiser MD421: 150 dB

89
Q

Icon credited with invention of artificial reverb

A

Bill Putnam

90
Q

Sibilance

A

High frequency of certain vocal sounds, particularly s, sh, ch, etc.

91
Q

What kind of EQ is sibilance?

A

De-esser

92
Q

Main difference between compressor and limiter

A

Ratio amount. Limiters will be at a higher ratio

93
Q

Rear port delay shift on a microphone

A

This is on every directional microphone because it is what makes a microphone directional. They modify path length from the back, resulting in cancellation.

94
Q

Every microphone would be omnidirectional if it doesn’t have this

A

Rear port delay shift

95
Q

Proximity effect

A

Bass frequencies increase in volume when closer to the mic

96
Q

What causes proximity effect?

A

This is caused by the rear rejection ports, therefore only affects mics that have cardioid or figure 8 patterns

97
Q

Type of mics that have rear phase rejection ports

A

All mics that are directional (not omni)

98
Q

What type of alcohol is used for rubber rollers on the MTR?

A

None. You don’t clean the rubber rollers with alcohol

99
Q

Two ways to view signal amplification on a console

A

RMS and Peak Amplification

100
Q

4 types of EQs

A
  1. Selectable frequency EQ
  2. Parametric EQ
  3. Graphic EQ
  4. Notch filter
101
Q

Q on EQ

A

Slope of the bandwidth

102
Q

Name the polar patterns and how they function

A
  1. Omnidirectional - picks up sound from all directions
  2. Bidirectional/Figure 8 - responds equally to sound from the front and back, while cancelling sound from the sides
  3. Unidirectional - cardioid: sensitive front, least sensitive back, supercardioid: sensitive front, some rear sensitivity, hypercardioid: very narrow front response, very responsive back pattern
103
Q

Anechoic chamber

A

Designed to not have any reverb and are technically 0 dB because there are no reflections - and if someone spoke while not facing you, you wouldn’t hear them

104
Q

Definition of frequency

A

The measurement of the number of cycles that occur in one second of time/ cycles per second; unit is Hz

105
Q

Speed of sound at 70 degrees F

A

1130 feet per second

106
Q

How does temperature change affect velocity?

A

For each degree increase, velocity increases by 1.1 ft

For each degree decrease, velocity decreases by 1.1 ft

107
Q

Phase shift and how it may amplify or attenuate

A

If two identical waveforms are in phase they will amplify, if they are out of phase by 90 degrees, it won’t change at all, and if they are out of phase by 180 degrees, they will cancel each other out.

108
Q

Parts of waveform envelope

A

Attack, Decay, Sustain, Release

109
Q

Attack

A

Time taken for amplitude to build up to max peak

110
Q

A

Pressure gradient microphones are directional (cardioid, figure 8)
Pressure operated microphones are omnidirectional

114
Q

Path to take aux sends from

A

Monitor path/the path returning from the MTR to be heard

115
Q

Best operating level from any analog device

A

Nominal

116
Q

Masking

A

Psychoacoustic phenomenon that occurs when loud sounds prevent the ear from hearing softer sounds, aka. loud sounds exceed threshold of hearing, causing quieter sounds to become inaudible to the brain

117
Q

Temporal masking

A

Time relationship between loud and soft sounds

118
Q

Pre-masking

A

Soft sounds will be masked by a louder sound slightly before the louder sound occurs (up to 40 ms prior)
