PRO6 Live Audio System
Owner’s Manual
OSC: Abbreviation for “oscillator” or
“oscillation”.
Out of phase: 1. A signal, being similar to
another in amplitude, frequency and wave
shape, but offset in time by part of a cycle.
2. 180° out of phase or having opposite polarity.
See Phase.
Outboard: External, as in an “external device”.
Outboard equipment: External equipment
used with the PRO6 Control Centre, but that is
not part of it.
Output: 1. The signal put out by a device.
2. The physical location of where a device sends
out a signal.
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 PRO6
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 PRO6 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.
