Glossary
Patchbay
A patchbay brings together the input/output jacks of a recorder or
rack-mounted equipment into one location so that connections can
be changed easily. This can help reduce the complexity of
connections that can occur as larger numbers of MIDI devices and
audio devices are used together. Connections can be changed easily
by connecting cables (patch cords) within the patchbay. A separate
type of patchbay is the MIDI patchbay, which can switch the flow
of MIDI messages, or change MIDI connections between devices.
Some models allow you to pre-program a set of connections, and
switch between such sets.
This system provides a virtual patchbay screen that allows you to
freely modify the correspondence between input jacks input
channels, and between bus outputs assignable output jacks.

Peaking type

A type of equalizer response curve in which the signal is boosted or
cut in the shape of a peak centered on the specified frequency. On
this system, the high-mid and low-mid channel equalizers are the
peaking type.
Shelving type
Pedal sw, Pedal switch
A switch-type foot pedal (such as the Roland DP-2), used for such
things as sustaining notes on a keyboard or entering and exiting
record mode on a recorder.
Foot sw
PFL
An abbreviation for Pre Fader Listen. A solo function that lets you
audition the signal before the channel fader and pan etc. On this
system, you can also solo the signal before it passes through the EQ.

Phantom power

6–48 V DC power supplied from a mixer via audio cables for a
condenser mic or direct box. On this system, the analog inputs with
XLR connectors provide phantom power (48 V). If this voltage is
applied to devices that do not require phantom power (such as
dynamic mics or audio playback devices), malfunctions or other
problems can occur, so phantom power should be switched off
when it is not needed.

Phase
In a cyclically modulating signal such as audio, the temporal
relationship expressed by dividing each cycle into 360 degrees is
called the "phase." Shifts or reversal (a 180 degree shift) in phase
produced by analog circuitry etc. can interfere with accurate
playback of the sound. On this system, the Phase setting of each
input channel allows you to intentionally reverse the phase to
correct such problems.

Phase delay

A special delay provided on each input channel of this system for
the purpose of compensating for discrepancies in phase.
This is used to correct the phase differences produced by time delay
when multiple mics are used on a single sound source. For example
if two mics placed at differing distances from the sound source are
used to record it, the sound picked up by the farther mic will be
delayed by 3 msec for each meter of distance. If these sounds are
mixed just as they are, the phase difference due to the time delay
will cause problems such as the cancellation of certain parts of the
frequency band. In such cases, the problem can be avoided by
applying a similar amount of delay to the input from the mic that is
nearer the sound source. Since the phase delay is used for this
purpose, only the delay sound is used (without mixing it with the
original sound).
Phase
Phaser
An effect that mixes a cyclically phase-shifted sound with the
original sound, in order to produce a sense of rotation,
spaciousness, or depth. It produces a characteristic "swooshing"
modulation.

Pink noise

Noise that contains equal amounts of energy in each octave of the
frequency spectrum. On this system, the internal oscillator can be
used to generate pink noise in the audio bandwidth. In sound
reinforcement applications, pink noise can be broadcast from the
main speakers, picked up by a mic and sent to the analyzer to
perform a detailed analysis of the acoustic character of the hall.

Analyzer

Pitch shifter

An effect that allows the pitch of the input signal to be freely
modified. The pitch-shifted signal can be mixed with the original
signal to produce modulation, or the effect can be used to correct a
sharp or flat vocal pitch.
Post-fader
Refers to a signal that has passed through the channel fader. The
volume level of a signal sent Post Fader will be affected by the
channel fader.
Pre-EQ
Pre-fader
Post-production
The process of using sophisticated editing equipment to add audio
material to video that was previously recorded on video tape or
film, in order to produce a completed video or movie with finished
sound and images.
Power supply, Power source
Something that provides the electrical power required for a device
to operate. For this system, an AC outlet.
Power switch
The switch that turns on a device. In this system, the power switch
of the console is located on the back panel, and the power switch of
the processor is located on the front panel. Each is labeled POWER.
