Pschycoacoustic noise: Noise that affects the
physiology of the listener.
Q
Quick access button: Button for navigation/
selection of a channel/bus/processing area.
R
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 effect
processor. See Bus.
Reverb: An effect 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 effective value
of measuring a sine wave's electrical power. A
standard in amplifier measurements. The
effective average value of an AC waveform.
RS: Abbreviation for "right surround". The
right-hand rear speaker in a 5.1 surround
system.
S
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
7kHz, 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 flow: 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 reflect 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 specifically designed
to show the condition of something. For
example, an LED that shows whether a
pushbutton is on or off, 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 different
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.
T
Tab: A 'sheet' in the From and To sections that
contains a specific group of patch connectors.
See Patching.
TFT: Abbreviation for "thin film 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.
