P
PICKUP POINT (PICK POINT)
An architectural or structural point to which scenery or trussing can be
rigged for flying purposes. Available pickup points in a particular venue
must be reconciled with necessary hanging points on the equipment to be
lifted.
PIGTAIL
In a permanent circuiting system, a short cable extending from a circuit box
which has a female connector into which a lighting instrument is plugged.
PIN CONNECTOR
A standard connector for stage cable which is also called a 2P&G connector
for 2 pins and ground. Pin connectors are generally rated for 20 amps at 120
volts and are the most common type of connector for the touring industry.
PIN PATCH
As part of a lighting control console, the pin patch is a matrix of pins
which allows individual dimmer control signals to be grouped together into
channels on a manual or preset board. The pin patch pre- dates the soft
patch found on most computer memory lighting control consoles.
PRE-HUNG TRUSS
A truss or truss section which has been pre-assembled with lighting
equipment and connecting devices in the shop prior to installation at
load-in. Using a pre-hung truss saves many hours when loading a show in or
out, and makes for an efficient method of storing equipment on a truck.
PRESET BOARD
A lighting ontrol console comprised of banks or "scenes" of redundant
sliders each controlling one channel of the lighting system. Individual
looks can be set up on banks and by using scene masters one look can be
faded to the next. The two-scene preset is the most common preset board.
Cues are manually set on alternate scene banks and faded from one to the
other. Multi-scene preset boards can also be found in some permanent
installations which can require multiple operators to preset.
PROGRAMMING
The process by which light cues are set-up, written, and recorded into
memory on a memory console. Programming on contemporary control consoles may
involve complex manipulation of functions and software, but rarely involves
actual program coding.
PROTOCOL
An electronic communication signal by which the electronic devices in a
lighting system can share information. Standard lighting protocols include
AMX, DMX, MIDI, as well as many proprietary protocols utilized by specific
manufacturers.
PAR LAMP / PARABOLIC ALUMINIZED REFLECTOR
an incandescent or tungsten-halogen incandescent lamp with a hard glass bulb
and an interior reflecting surface, a precisely placed filament, and a lens
to control beam spread. The lens is hermetically sealed to the reflector.
Metal halide PAR-lamps are also now available.
PARABOLIC LOUVERS
Parabolic louvers control luminance precisely; they consist of multiple
cells with parabolic reflectors, and a specular or semi-specular finish. The
cells range in size from ½ in. X ½ in. to 1 ft X 1 ft.
