Stage Lighting Control System: A Comprehensive Solution for Theater Productions

5 Minute Read

In live theater, lighting does more than illuminate—it sets the mood, directs audience focus, and enhances the narrative. A reliable lighting control system is critical, and this setup, powered by Sundrax’s GigaJet20 Pro, delivers exceptional reliability, flexibility, and safety for professional productions. Designed for lighting designers, stage managers, and technicians, it ensures seamless performance in high-pressure environments. 🌟

Scheme Overview: Front of House and Fiber Optic Backbone

The Front of House (FOH) is where the «Stage-Head» lighting designer’s console sits, loaded with cue lists and show programming. Data zips from there through a fiber optic connection to a Sundrax GigaJet20 Pro—a robust device designed for high-performance signal management. This first GigaJet20 Pro sends all DMX universes to a second unit near the stage, ensuring fast, interference-free transmission over long distances. That’s key for spot-on lighting during live shows. 🎭

The GigaJet20 Pro is a multi-protocol DMX converter with 20 optically isolated DMX ports—perfect for big theater gigs. It’s tough too, handling 0–60°C, 95% humidity, and 310V surge protection.

Dual-Console Setup: Flexibility and Redundancy

Near the stage, a secondary console—operated by a stage manager or technician—adds an additional layer of control. The stage-side GigaJet20 Pro employs advanced merging algorithms (HTP, LTP, AUTO, PRIORITY) to enable smooth transitions between consoles or manual overrides without disrupting the show. This configuration ensures flexibility for real-time adjustments and redundancy for emergencies. 🔧

The system includes a back-up function that maintains continuous signal transmission. If the FOH console fails due to power issues or technical glitches, the back-up console ensures the performance continues uninterrupted—a critical feature for theater professionals.

Hardware Triggers: Automation for Safety and Efficiency

The stage-side GigaJet20 Pro features two hardware trigger inputs (via terminal block) that enhance functionality:

  • Maintenance Trigger: Activates technical lighting presets for tasks like cleaning or equipment checks, illuminating the stage without requiring the lighting crew. 💡
  • Emergency Trigger: Configurable inputs can respond to external signals, such as a fire alarm, automatically triggering pre-set lighting scenes for evacuation. 🚨

— No operator is needed to operate the triggers. 🚨

These features streamline operations and comply with theater safety regulations, prioritizing audience and staff safety.

DMX Ports and Fixture Control: Power and Precision

The stage-side GigaJet20 Pro manages 20 DMX ports, each optically isolated to prevent interference and ensure stability. If one port fails, the others remain operational—a significant advantage for live events. These ports support RDM (Remote Device Management) for real-time fixture monitoring and configuration, as well as motion tracking for dynamic effects. 🌌

Compatible with a wide range of fixtures, from traditional PAR cans to modern moving heads, the system is highly versatile. Sundrax’s emphasis on signal processing, merging, and back-up capabilities makes the GigaJet20 Pro a reliable choice for any theater production.

Case Study: A Night at the Opera

Consider a grand opera production with over 100 fixtures—moving heads, LED panels, and classic spotlights. The GigaJet20 Pro’s 20 DMX ports manage this setup effortlessly, while RDM enables technicians to monitor all fixtures in real time. During the show, a power surge disables one port, but optical isolation ensures the remaining ports function flawlessly, keeping the performance uninterrupted. The stage manager makes real-time adjustments from the secondary console, synchronizing lighting with the performers’ movements. 🌟
