What are line array speaker rigging and safety best practices? | Insights by T.i Audio

1. What Are Line Array Speakers and Why Is Proper Rigging Essential?

Line array speakers are vertically stacked loudspeaker modules designed to create a controlled, long-throw sound field for concerts and large events. Proper rigging is crucial as it directly affects coverage consistency, intelligibility, and structural safety. ((https://www.ti-audio.com/line-array-setup-rigging-guide.html))

2. What Are the Key Steps in Rigging Line Array Speakers Safely?

Pre-Rig Inspection and Planning:

Before installation, conduct a safety meeting with all crew members to review the lift plan, weight calculations, hardware certificates, emergency procedures, and communication signals. Inspect all components for wear, deformation, corrosion, and proper lubrication. ((https://www.ti-audio.com/rig-fly-line-array-speakers-safely.html))

Trial Assembly on Ground:

Assemble the array on the ground to confirm rig geometry, correct splay angles, and audio alignment. Verify that the fly frame mates with each module as intended and that rigging pins, locks, and safety catches function properly. ((https://www.ti-audio.com/rig-fly-line-array-speakers-safely.html))

Attaching Safety Backups and Secondary Restraints:

Each flown array should have a secondary safety restraint, such as a certified steel safety cable or redundant shackles routed independently of the primary rigging path. This backup is required wherever speakers are flown over people. ((https://www.ti-audio.com/rig-fly-line-array-speakers-safely.html))

Executing the Lift and Trim:

Use qualified, certified hoist operators. Lift slowly and smoothly, watching for unexpected load shifts. Keep nonessential personnel clear of the area beneath the lift until the array is secured and safety inspections are complete. Trim the array to the desired height and angle, then torque and lock all rigging pins and bolts per manufacturer torque specifications.

3. What Are the Environmental and Operational Safety Considerations?

Weather, Wind, and Outdoor Risks:

Wind is a primary hazard for flown line arrays outdoors—gusts create large dynamic loads and can change array behavior. Follow manufacturer wind limits and local regulations. Lower or secure flown arrays before forecasted high winds or storms. ((https://www.ti-audio.com/rig-fly-line-array-speakers-safely.html))

Crowd Protection and Exclusion Zones:

Establish exclusion zones under and around flown loads. Barriers and signage keep the public clear. For events with a crowd beneath a flown array, ensure all secondary safety systems are in place and documented. Coordinate with event management and local authorities for compliance.

4. How Should Rigging Hardware Be Selected and Maintained?

Choosing Rated Hardware and Applying Safety Factors:

Always use certified rigging hardware with traceable Working Load Limits (WLL). Apply at least a 5:1 safety factor for human-occupied spaces whenever local regulations require it. ((https://www.ti-audio.com/line-array-setup-rigging-guide.html))

Routine Checks and Recordkeeping:

Inspect rigging points and hardware before and after each flight. Maintain records of certificates, inspection tags, torque values, and any maintenance work. Schedule periodic load tests and replace hardware per manufacturer service intervals or when wear is detected. ((https://www.ti-audio.com/rig-fly-line-array-speakers-safely.html))

5. What Are the Best Practices for Rigging Line Array Speakers?

Pre-Installation Planning:

Accurately determine the total weight of the array, including speakers, rigging hardware, and cabling. Verify the load-bearing capacity of the ceiling or structure where you'll be hanging the array. Consult a structural engineer if you have any doubts. ((https://www.ti-audio.com/article/hanging-line-arrays-a-guide-t-i-audio.html))

Rigging Hardware Selection:

Choose appropriate rigging hardware (chains, shackles, turnbuckles, etc.) with a safety factor significantly exceeding the calculated weight. Use only certified and appropriately rated equipment. ((https://www.ti-audio.com/article/hanging-line-arrays-a-guide-t-i-audio.html))

Array Configuration:

Design your array configuration based on the venue's acoustics and the desired coverage pattern. Software tools can be invaluable here. ((https://www.ti-audio.com/article/hanging-line-arrays-a-guide-t-i-audio.html))
