Q

Condenser microphone

A

2 metallic plates (diaphragm and back plate) that have charge between them in the form of a battery or phantom power - the distance between the two plates changes with sound waves, creating a charge that travels down the mic and into the cable

Q

Noise gate

A

An effect that used a gate that opens and closes. When the level of a signal falls below the threshold, the gate closes and no sound signal is allowed through

21
Q

Aux send

A

An electronic signal-routing output used on multichannel sound mixing consoles - allows effects to be added to an audio source or channel within the mixing console

22
Q

Pan

A

Reduces or reverses the stereo width of a stereo signal between the left and right channels

23
Q

Channel fader

A

Fader on the mixer that controls the level of that channel in the overall mix

24
Q

Main output

A

Fader that controls house speakers

25
Q

Monitor output

A

Fader that controls the monitor levels

26
Q

Amplifier

A

Used to power a speaker or monitor

27
Q

Pre-amp

A

A device used to boost the level of signal from mic level to line level, sometimes colouring, EQing, or cleaning up the signal at the same time

28
Q

Tube amp/pre-amp

A

Boosts the signal level by sending it through a series of transistors

29
Q

Solid state amp/pre-amp

A

Boosts the signal level by sending it through a series of transistors.

30
Q

Hybrid pre

A

Used solid state circuitry for the input, and vacuum tube to drive the output

31
Q

IEM Systems

A

“In ear monitor”

A device that fits inside the ear that gives a performer their monitor mix

32
Q

Send

A

An outboard processor to which typically processes only part of a signal

33
Q

Insert

A

Processes the whole signal

34
Q

Compressor

A

Maintains consistent levels across a whole song by attenuating the largest signals, and sometimes boosting the lowest signals

35
Q

Threshold

A

The level that the signal has to reach before the compressor starts working

36
Q

Ratio

A

The amount the signal will be compressed.

Input level:output level

37
Q

Attack

A

How quickly the compressor starts working after the threshold is passed

38
Q

Short throw projector

A

A projector that can be placed within close proximity to a screen while still maintaining a large clear image

39
Q

Long throw projector

A

A projector that needs to be placed a certain distance from the screen in order to project a clear image that is large enough.

40
Q

VGA

A

16-pin, most common computer projector connection

41
Q

HDMI

A

Hi-def projector computer connection b

42
Q

Delay

A

An effect that records incoming sound, and plays it back as a fading echo

43
Q

Reverb

A

An effect used to recreate the natural reverberations of sound that occur in a given space

44
Q

Multi-effect processor

A

Processes sound in many different ways

45
Q

Sub-grouping

I’m

A

The process of assigning more than one channel to a group so that you can apply effects or change the level of more than one channel at once

46
Q

What is a line check

A

The process of ensuring all sound sources from the stage are sending a signal to the sound board

47
Q

What are the typical problems that arise while doing a line check?

A

Bad cables, bad connections, incorrect signal routing,

48
Q

3 steps to problem solve a line check

A
  1. Check the obvious
  2. Trace the signal
  3. Swap equipment
49
Q

Gain control/ trim control

A

The volume control for each channel on a mixing console

50
Q

Trimming

A

Changing the level of a signal up or down

51
Q

3 phases of mixing

A
  1. Create a general mix
  2. Develop a distinct mix
  3. Evaluate mix consistency
