PERFORMANCE LIGHTING CONTROL

 For combo, touring show, club, theatre, school, or "house and road" use, the GTS selection includes the price and capability you need. Units are compact, many portable, easy to install and use, many priced with 2 grounded "Edison" sockets per channel (other connectors available). GTS offers a very wide range of analog and digital systems in many fixed and portable configurations. Listed units we have found most suitable for most needs and budgets. Other systems information is available on request.
Excepting Scenemasters all are modular expansion systems which permit growth and change with YOUR NEEDS, avoiding expensive replacement. Most are digital systems using small diameter DMX control cable and allowing pre-programming of a few scenes to major productions for selective cueing with the push of a button. If you use repetitive lighting sequences, more than 3 dozen dimmers, or require fast scene changes, you need digital storage. If your analog equipment includes 12 or more dimmers and is showing its age, consider an interface control module to upgrade your console with minimum cost. All listed dimmers are suitable for incandescent, quartz, and simple inductive lamps. Request assistance with fluorescent, neon, display and architectural applications.
Begin your research by printing a copy of this file for each person involved with production or finance decisions, then contact GLOBE THEATRICAL for planning assistance and product brochures. GTS does no installations, however, your local electrician will have no difficulty installing current modular units and we're here to discuss optimal layouts. When the most likely module selections have been made, request installation/operation manuals for a detailed understanding and comparison of the equipment. Request information regarding integrated or separate architectural lighting or other non-stage control systems.

GTSAIDS: UNDERSTANDING STAGE LIGHTING

                Overview

All performance light control systems require a power source, distribution wiring from the dimmers to the lighting units, dimmers, and a control panel. Usually the most expensive portion is the power source and distribution, the dimmers are next, and the control console the least expensive. If a desired system cannot be initially purchased in its entirety, budget for power source, distribution, and console. This enables easy later addition of more dimmers and lights as budgets permit.

                Power On

THIS is where YOUR lighting system begins. Whether permanent, semi-permanent, or portable, the most important question is "Where is the power coming from?" Realize that most stage lamps are in increments of 500 watts which is about 5 amps of power at 110 volts. This roughly equates as 100 to 120 amps per every 20 lighting instruments. This reality usually determines the approach to portable systems, but even permanent installations in older venues may require additional power to the breaker boxes at the lighting location. Simply stated, available power dictates quantity of lighting units which then allows selection of instrument locations.
Open area (non-proscenium) locations permit enormous lighting freedom and commonly require custom power distribution planning. Proscenium stages require minimum three lines (usually four) of lighting (outlet strips): along the back drape (background lighting), one or more inside the proscenium arch (lighting most of the stage), and in front of the stage (lighting the stage at and in front of the proscenium opening). These latter down stage lighting outlets are generally located near the auditorium ceiling and/or along the auditorium back wall and generally include outlets numbered starting with dimmer circuit 1. Although any sequence can be arranged, traditionally the outlets are numbered sequentially from stage left to right and from down stage to up stage with numbers printed by the up stage facing outlets, allowing on stage left to right reading. Multiple outlets per circuit arecommonly sequentially repeated; e.g., from stage left for 24 1,200 watts dimmers:
(auditorium) 1 2 3 4 5 6 1 2 3 4 5 6
(inside arch) 7 8 9 10 11 12 7 8 9 10 11 12
(mid-stage) 13 14 15 16 17 18 13 14 15 16 17 18
(back drape) 19 20 21 22 23 24 19 20 21 22 23 24.
This allows plugging 48 500-600 watts lighting units.
Next, it is necessary to decide the number of lights per dimming circuit. Ideally, every lighting designer prefers each fixture be independently controlled; but, since the dimmers are generally the most expensive control unit and are in increments of 1,200 watts per circuit, economics encourages planning minimum two instruments per circuit (like the above example). In small venues this is advisable. Larger facilities should consider 2,400 or 3,600 watts (capable of 4 to 7 fixtures) or larger circuits. Decide which circuits to allocate at which stage depths. This is the final decision necessary to determine the quantity of outlets in each distribution strip.
Other than structural support planning (request assistance), consider outlet type. Anywhere rough handling, including traffic vibration, is projected, use a twist lock. Drop-cords usually include twist lock or stage pin receptacles. Mounted parallel blade grounded ("household") outlets permit easy use with table lamps, holiday decorations, special effects equipment, etc. without an adapter cable, and should be considered for small to moderate sized installations.
When ready for further assistance, contact Globe Theatrical 712/255-0972.

                Lights Up

Excepting limited power Scenemaster analog portable dimmers, dimmer "packs" or rack cabinets include several remote controlled dimmers in a single unit which is separate from the control console. For easy input and output wiring, generally the dimmers are located on or near the stage and the power source breaker panel. Unless the packs are to be used portably, the input cables are normally "hard-wired" from the breaker to pack terminal posts. For portable applications the pack wattage usually determines the input connections - request assistance. The distribution wiring may also be hard-wired from dimmer terminal strips to the lighting locations. If portability or manual patching is desired, various types of outlets may be mounted on the pack. (Note: Manual patching is the act of physically removing a distribution cable plug from a dimmer outlet then "patching" by plugging it into an outlet controlled by a different dimmer. Many digital dimmer/console systems now permit digital patching to reassign lighting outlets to any console channel without physically moving any wiring.)
A basic system includes a dimmer for each distribution circuit, and a console manual control channel for each dimmer; i.e., 24 dimmers need a 24 channel console. Large complex systems may be configured to allow several electronically assignable dimmers to be controlled by any console channel. The exception is computer monitor "full channel" (512 or more channels) preprogrammed cues consoles which require "writing a script program" of cues to be stored then selected on screen and activated when needed.
There are many combinations of dimmer and console capabilities. The following terminology should prove helpful when analyzing component capabilities.

LIGHTING CONTROL CLASSIFICATION: Lighting dimmers (and other electronic controllers) can be initially classified by several key design characteristics which determine specific application suitability. Consider first:
MODULAR: A component system including minimally a power-pack/cabinet-dimmer, usually with no controls, and a control console which remotely controls the dimmers via cable(s).
EXPANDABLE: Modular system allowing periodic addition of power-packs, more sophisticated controllers or other components, such as video monitors, disk drives, keyboards, audio sources, etc.
MANUAL OPERATION: Manual control required. All switches and channel faders (dimming controls) must be preset before each scene is required. 1-scene control requires dimming modification as the scene is changed; 2-scene consoles permit pre-setting the next dimmer settings before cross-fading to that scene.
MEMORY STORAGE: Built-in computerized control circuits. Many scenes may be preset and saved to memory for extended storage and rapid recall. Most systems include one or two sets (scenes) of manual faders allowing manual console operation by temporary users wishing to avoid learning memory programming.
ANALOG REMOTE CONTROL: A separate set of 2-3 wires is needed to carry variable low voltage (usually 0-10v) control to each dimmer.
DIGITAL REMOTE CONTROL SIGNAL: Many linked dimmers (up to 1,000) may all be computer addressed (multiplexed) through the same 3 to 7 wire control cable.
MULTIPLEX: Digital control signal code systems (languages). Available formats include DMX512, AMX192, CD80, CMX, CDM, FOM, Micro-Plex (MPX), and others. Some dimmers can be set to read different codes or communicate via fiber-optic cable.
ELECTRONIC PATCHING: The capability of a dimmer to accept control channel assignments from the control console (software patching), thus eliminating the need to manually patch the dimmer to reassign control channels to output destinations.
INTERFACE: Electronic circuit which allows electrical connection or electronic communication between different devices. Most common are DA (digital to analog) decoders, SMPTE, MIDI, RS232, USB, or parallel ports, and audio inputs.
INTERCOMPATIBLE: All expandable systems GTS lists minimally use analog 0-10 volts, DMX512, or MIDI control signals, allowing mix-&-match use with any components using the appropriate same of these common standards. Some of the listed components utilize more than one control format, allowing greater expansion, parallel linkage, or system revision adaptability, including effects, motorized light units, and powered stage mechanicals to be controlled from the light board.
HYBRID SYSTEM: Mixed system including analog & digital modules. Usually such systems include a demultiplexer which converts digital control signals to analog outputs allowing inexpensive control conversion using a digital console while retaining older analog dimmers.
KEEP IN MIND that GTS handles many unlisted brands of light control and associated equipment. No matter how old or new your current equipment check with GTS for conversion/expansion assistance.
