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

Monitor Insert switch
86
(MP100 Study Guide) What kind of microphone has the best transient response? -what NOT to choose-
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
(MP100 Study Guide) Which mic has the best SPL rating?
The answer will be a dynamic mic
88

90
Sibilance
High frequency of certain vocal sounds, particularly s, sh, ch, etc.
91
What kind of EQ is sibilance?
De-esser
92
Main difference between compressor and limiter
Ratio amount. Limiters will be at a higher ratio
93
Rear port delay shift on a microphone
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
Every microphone would be omnidirectional if it doesn't have this
Rear port delay shift
95
Proximity effect
Bass frequencies increase in volume when closer to the mic
96
What causes proximity effect?
This is caused by the rear rejection ports, therefore only affects mics that have cardioid or figure 8 patterns
97
Type of mics that have rear phase rejection ports
All mics that are directional (not omni)
98
What type of alcohol is used for rubber rollers on the MTR?
None. You don't clean the rubber rollers with alcohol
99
Two ways to view signal amplification on a console
RMS and Peak Amplification
100
4 types of EQs
1. Selectable frequency EQ
2. Parametric EQ
3. Graphic EQ
4. Notch filter
101
Q on EQ
Slope of the bandwidth
102
Name the polar patterns and how they function
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
Anechoic chamber
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
Definition of frequency
The measurement of the number of cycles that occur in one second of time/ cycles per second; unit is Hz
105
Speed of sound at 70 degrees F
1130 feet per second
106
How does temperature change affect velocity?
For each degree increase, velocity increases by 1.1 ft
| For each degree decrease, velocity decreases by 1.1 ft
107
Phase shift and how it may amplify or attenuate
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
Parts of waveform envelope
Attack, Decay, Sustain, Release
109
Attack
Time taken for amplitude to build up to max peak
110
Decay
Initial decay/attenuation after attack
111
Sustain
Changes in amplitude as note is held out
112
Release
Final tail of sound as note is finished
113
Pressure gradient v Pressure operated microphones
Pressure gradient microphones are directional (cardioid, figure 8)
Pressure operated microphones are omnidirectional
114
Path to take aux sends from
Monitor path/the path returning from the MTR to be heard
115
Best operating level from any analog device
Nominal
116
Masking
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
Temporal masking
Time relationship between loud and soft sounds
118
Pre-masking
Soft sounds will be masked by a louder sound slightly before the louder sound occurs (up to 40 ms prior)
119
Post-masking
Soft sounds will be masked by a louder sound slight after the louder sound occurs (up to 200 ms after)
120
Bus definition
A common signal line
