Quiz 7

Question 1

Mixer/Console/Board/Control Surface

Answer 1

They take input sources and route them to output sources such as broadcast, recording and digital audio workstations (DAW)

Question 2

Active Microphone Mixer

Answer 2

a live sound mixing device that automatically reduces the strength of a microphone’s audio signal when it is not being used. Automixers lower the hiss, rumble, reverberation and other extraneous noise that occur when several microphones operate simultaneously. They may also be used to mix sound from non-microphone signals such as playback devices.

Question 3

Phantom Power

Answer 3

a method for transmitting DC electric power through microphone cables to operate microphones that contain active electronic circuitry

Question 4

Mic or Line input

Answer 4

Mic is Lower signal Strength than the Line signal

Question 5

Pad

Answer 5

a sustained chord or tone generated by a synthesizer, often employed for background harmony and atmosphere in much the same fashion that a string section is often used in acoustic music

Question 6

Gain

Answer 6

A compression control that allows adjustment of the output level to the desired optimum. Used, for example, when loud parts of a signal are so reduced that the overall result sounds too quiet.

Question 7

Equalizer

Answer 7

A signal-processing device that can boost, attenuate, or shelve frequencies in a sound source or sound system.

Question 8

Filer

Answer 8

A device that removes unwanted frequencies or noise from a signal.

Question 9

High Pass Filter

Answer 9

A filter that attenuates frequencies below a selected frequency and allows those above that point to pass.

Question 10

Pan Pot

Answer 10

Short for panoramic potentiometer. A vol- ume control that shifts the proportion of sound from left to right between two output buses and, hence, between the two loudspeakers necessary for reproducing a stereo image, or among the six (or more) surround-sound channels, and loud- speakers, necessary for reproducing a surround- sound image.

Question 11

Solo Mute

Answer 11

Turns off the signal from a channel/track

Question 12

VU Meter vs Digital Meter

Answer 12

A meter that responds to the average voltage on the line, not true volume levels. It is calibrated in volume units and percentage of modulation. The benefits of a digital meter include the fact that there is no mechanical inertia to overcome and tend to therefor be more accurate to the digital sound.,

Question 13

Master Section

Answer 13

In a multichannel production console, the section that routes the final mix to its recording destination. It usually houses, at least, the master controls for the mixing bus outputs, reverb send and reverb return, and master fader.

Question 14

Patch Bay

Answer 14

An assembly of jacks to which are wired the inputs and the outputs of the audio compo- nents in a console and/or sound studio. Also called patch panel.

Question 15

Jack

Answer 15

Receptacle or plug connector leading to the input or output circuit of a patch bay, a recorder, or other electronic component.

Question 16

Patch Cord

Answer 16

A short cord or cable with a plug at each end, used to route signals in a patch bay.

Question 17

Multiple

Answer 17

(1) On a patch bay, jacks interconnected to each other and to no other circuit. They can be used to feed signals to and from sound sources. Also called mults. (2) An amplifier with several mic-level outputs to provide individual feeds, thereby elimi- nating the need for many. Also called a press bridge or a presidential patch.

Question 18

Tie line

Answer 18

Facilitates the interconnecting of outboard devices and patch bays in a control room or between studios.

Question 19

Anechoic Chamber

Answer 19

A room that prevents all reflected sound through the dissipation or the absorption of sound waves.

Question 20

Frequency Response

Answer 20

A measure of an audio system’s ability to reproduce a range of frequencies with the same relative loudness; usually represented by a graph.

Question 21

Distortion

Answer 21

The appearance of a signal in the reproduced sound that was not in the original sound.

Question 22

Sensitivity

Answer 22

1) Measurement of the voltage (dBV) a microphone produces, which indicates its effi- ciency. (2) The sound-pressure level directly in front of the loudspeaker, on-axis, at a given distance and produced by a given amount of power.

Question 23

Far Field Monitoring

Answer 23

Monitoring sound at the listening position from large, powerful frontal loudspeakers several feet away and usually built into the mixing-room wall.

Question 24

Near Field Monitoring

Answer 24

Monitoring with loudspeak- ers placed close to the operator, usually on or just behind the console’s meter bridge, to reduce interfer- ence from control room acoustics at the monitoring position.

Question 25

60% 60minute Rule

Answer 25

Limit listening through headphones to no more than one hour per day at levels below 60 percent of maximum volume.
