S
STRIKE
The process by which the scenery and lighting equipment for a show is
permanently disassembled when the tour or production closes.
STRIPLIGHT
1) A thin linear filament lamp similar to an Architectural, but having
contacts at the ends of the lamp. Available clear or opaque.
STROBE
Device giving a fast series of very short intense light flashes which can
have the effect of making action appear intermittent. Because strobe
lighting can trigger an epileptic attack in sufferers, the use of a strobe
must be communicated to the audience before the performance begins. Strobes
should be synchronised so that they operate outside the dangerous frequency
band 4 to 50 flashes per second. (i.e. a strobe should operate at less than
4 flashes per second, or more than 50 flashes per second). If the effect is
momentary, this rule may be relaxed. Strobes must never be used in public
areas where there are changes of level or steps.
Always seek the advice of the licensing authority if you are in any doubt
about the safety of strobe effects.
STROBE CANNON
A type of strobelight mounted in a PAR64 housing. Some strobe cannons, such
as the Diversitronics model, can be remotely controlled via a DMX control
signal.
STROBE LIGHT
- A light that flashes on and off quickly.
- A special lighting effect which produces multiple rapid bursts of high intensity light. Strobe lighting is almost always produced by a compact xenon strobe lamp activated by a power supply and timing circuitry. Strobelights can be simple low power devices with fixed flash rates, or sophisticated devices triggered by a lighting control console at specific intervals.
SUBMASTER
Fader on a lighting desk which can have a lighting state recorded onto it
for additional control, or to use when manually mixing lighting states for
music concerts or one-off events.Lighting desks normally have a series of
submasters (12 or 24 are common) which can have states, cues or effects
loaded onto them. Some desks can have submasters set to inhibit the main
output (known as INHIBITIVE SUBMASTER. For example, the FOH lighting can be
loaded onto a submaster which is then brought down as the house tabs are
flown in between curtain calls to block light spill onto the tabs). Multiple
cues can be recorded onto some submasters through the use of pages. A
PILE-ON submaster can be used to add it's contents to the existing lighting
state. Any number of pile-on submasters can be used in combination to modify
a state.
SUBWOOFER
Speaker used to boost low frequency sound only.
SUPER TROUPER
Manufactured by Strong International - a range of high intensity followspots
designed for large scale permanent installations or large touring shows. The
Super Troupers use Xenon lamps and vary from 1600 - 2000W. The Super Trouper
is the best known of all stage lighting instruments outside of the industry
due to Abba's song "Super Trouper".
SURE TOUCH
Ryger's Method of ensuring that a touch pad has definitely been touched and
is not due to external electrical noise or dampness that can affect some
other controllers with touch pads.
