DIGITAL RACK MIXER M32R User Manual
Output fast strip:
One of 16 channel strips in the output fast zone.
Provides detailed control of the currently selected outputs. See Output fast zone.
Output fast zone:
Control area for fast access to primary main output functions.
Overload:
A condition where the signal level is too high.
Overview:
The main view in the GUI channel strip, which contains the control
sections of the selected channel. This represents the associated channel strip on
the control surface.
Overview screen:
One of the GUI screens. This is the default screen of the
mix bay.
P
PAN:
Abbreviation for ‘panoramic’.
Panning:
The left/right positioning of a signal across a stereo image.
Parameter:
A setting whose value can be altered by the user.
Parametric EQ:
A type of EQ that allows all of the parameters of equalisation to
be changed, including centre frequency, boost/cut in gain and bandwidth.
Patch:
A temporary connection (physical or virtual) made between two audio
devices or inside one.
Patch connector:
Any tab patching point, for example, an XLR connector, bus,
sidechain compressor etc. See Patching.
Patching:
Also known as ‘soft patching’. The process of routing a channel/signal
from a source to a destination(s).
PCB:
Abbreviation for ‘printed circuit board’.
PEQ:
Abbreviation for ‘parametric equaliser’. See Parametric EQ.
PFL:
Abbreviation for ‘pre-fade listen’. A function that allows the signal to be
monitored pre-fader, that is, before it reaches the fader.
Phantom power:
The power required for the operation of a condenser
microphone when it is not supplied by internal batteries or a separate
power supply. This is supplied by the M32 Control Centre itself.
Phase:
A measurement (in degrees) of the time difference between
two waveforms.
Pitch:
A continuous frequency over time. Musical interpretation of an
audio frequency.
Pitch shift:
Alteration of pitch or frequency, but without adjusting tempo.
Point scene:
Subdivision of a scene. See Scene.
Pointer:
1. On the GUI, the pointer is the arrow-shaped object on the screen
that moves when the user moves the trackball or external mouse. 2. On a control
knob, it is the marking that, when used in conjunction with the ident around
edge of control knob, helps to indicate the setting.
POP:
Abbreviation for ‘population’.
POP group:
A number of channels assigned to a group that has unfold and area
B controls. Provides an easy and quick method of manipulating and controlling
the numerous channels available on the M32 Control Centre.
Post-:
The point for accessing audio just after it leaves a specific channel
component, for example, ‘post-fader’, where the audio is tapped from just after it
leaves the channel’s main level control.
Pre-:
The point for accessing audio just before it reaches a specific module, for
example, ‘pre-EQ’, where the audio is tapped from just before it gets to a channel
strip’s EQ.
Primary navigation zone:
Area in the master bay for mix and master bay GUI
screen navigation and control. Also has a screen access section for fast access to
GUI menu options.
Processing area:
A display in a GUI channel strip showing a specific control
section. Accessed from the channel’s overview display. See Overview.
PSU:
Abbreviation for ‘power supply unit’.
Psychoacoustics:
The study of the perception of sound, that is, how we listen,
our psychological responses and the physiological effects on the human nervous
system.
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 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 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.
