Psychoacoustics: The study of the perception of sound, that is, how we

listen, our psychological responses and the physiological eects on the human

nervous system.

Pschycoacoustic noise: Noise that aects the physiology of the listener.

Quick access button: Button for navigation/ selection of a channel/bus/

processing area.

RAM: Abbreviation for ‘Random access memory’.

Return: Auxiliary return or aux return. An extra input used for receiving a signal

from the output of an internal or external eect processor. See Bus.

Reverb: An eect where the ambience of a physical space is simulated. This is

done by copying a signal and replaying at regular intervals at ever decreasing

levels. The intervals are so close that each copy is not heard individually.

RMS: Abbreviation for ‘root-mean-square’. The square root of the mean of the

sum of the squares. Commonly used as the eective value of measuring a sine

wave’s electrical power. A standard in amplier measurements. The eective

average value of an AC waveform.

RS: Abbreviation for ‘right surround’. The right-hand rear speaker in a 5.1

surround system.

s: Symbol for ‘second’. A unit of time.

Scene: In automation, a set of mix settings for a particular part of a performance,

for example, a play or song.

Sibilance: Energy from a voice, centred around 7 kHz, and caused by

pronouncing ‘s’, ‘sh’ or ‘ch’ sounds.

Side chain: A special circuit that diverts a proportion of the main signal so that

it can be processed, as required. Compressors use the side chain to derive their

control signals.

Signal ow: The path of a signal from one place to another.

SIP™: Abbreviation for ‘solo in place’.

SIS: Abbreviation for ‘spatial imaging system’. Combines a central loudspeaker

cluster with a left-right system to form three discrete sound channels.

Snapshot: A captured group of mixer settings that reect the state of the mixer

at a particular moment within a performance. This snapshot can then be recalled

at the required moment in the performance/playback.

Solo: During monitoring, the isolation of one signal by silencing all other signals.

Source: The patch connector from which a signal is patched. See Patching.

SPL: Abbreviation for ‘sound pressure level’. Given in decibels (dB), SPL is an

expression of loudness or volume.

Splash screens: The GUI display during power up.

SRC: Abbreviation for ‘sample rate converter’.

SSD: Abbreviation for ‘solid-state disk’. Data storage device that uses non-

volatile memory to store data. Quicker than the conventional hard disk and less

susceptible to the failures associated with hard disk drives.

Status indicator: A device specically designed to show the condition of

something. For example, an LED that shows whether a pushbutton is on or o, or

a meter showing the level of a signal.

Stereo: Two separate channels, left and right, used to give the listener the

perception of where the noise is coming from. Usually used with music to give a

fuller, more natural sound.

Stereo image: The perception of the dierent sound sources coming from far

left, far right or anywhere in between.

Surround: Audio that has more that two speaker locations and, therefore,

more than two channels. Also commonly termed ‘surround sound’.

Synchronisation (sync): Coordination of timing between devices.

Tab: A ‘sheet’ in the From and To sections that contains a specic group of patch

connectors. See Patching.

TFT: Abbreviation for ‘thin lm transistor’.

Threshold: Level at which dynamics processing will begin to operate.

Tie line: A dedicated connection between two systems, typically between FOH

and MON positions.

To section: The rightmost area of the Patching screen that contains the

destination patch connectors. See Patching.

Tooltip: The information box that appears next to the pointer when it passes

over or pauses on items on certain GUI screens, such as the channels on the

Overview and Patching screens.

Touchpad: Also known as ‘trackpad’. An input device on a laptop PC for

controlling the on-screen pointer.

Track: Single stream of recorded audio data.

Trackball: Device, located in the primary navigation zone, for GUI screen

navigation and control of the mix and master bays.

Treble: Higher frequencies in a signal.

TW: Abbreviation for ‘twin-wire’.

Unbalanced audio: A type of audio connection that utilises only two of the

leads of a cable, connector and jack.

Unfold: Navigates the input channels of a group to the input bays.

USB: Abbreviation for ‘universal serial bus’. A ‘plug and play’ interface that

provides a fast connection between a computer and peripherals, such as

keyboards, printers, scanners, digital cameras etc.

VCA: Abbreviation for ‘variable control association’ (also ‘voltage

controlled amplier’).

VCA fader: The fader control of a VCA group.

VCA group: A group of channels that are controlled globally, such as via

their group’s fader and other controls. Provides an easy and quick method of

manipulating and controlling the numerous channels available on the M32

Control Centre.

VGA: Abbreviation for ‘video graphics array’. A graphics display system for PCs

developed by IBM.

Virtual rack: A traditional 19” rack, represented on the GUI. A virtual rack will,

typically, contain internal devices, such as eects and GEQs.

Volt (V): A unit of electrical potential dierential or electromotive force.

Volume: General term for a signal’s loudness.

Window: A small self-contained panel that appears on the GUI, usually after

selection of a specic control. Typically, contains a number of user-selectable

options or information in the form of a message or prompt.

X-over: Abbreviation for ‘crossover’.

XLR connector: High-quality three-pin audio connector, which is also used for

AES/EBU digital audio connections.
