A Line Array is a loudspeaker system engineered for precise directional control, delivering consistent coverage over long distances and wide environments. This makes it an ideal solution for stages, auditoriums, and large-scale events,stable sound distribution is essential for the audience.
In this guide, you’ll learn the core principles of line array technology, how to choose the right line array modules, and how to configure the system properly for venue size, coverage requirements, and performance expectations.
1. Basic Concepts of line array
A Line Array consists of multiple speaker modules arranged in a vertical or straight configuration, either flown or ground-stacked, designed to deliver phase-coherent sound while minimizing WAVE interference. Unlike traditional point-source speakers, Line Arrays provide controlled horizontal and vertical dispersion, ensuring more uniform coverage and reducing “hotspots” and “dead zones.”
Many professional brands develop advanced Line Array systems featuring integrated DSP, flexible rigging, and high-output performance.
2. Benefits of Line Array Systems
- Even sound coverage over long distances with reduced SPL variation from near to far positions.
- Minimizes unwanted reflections and excessive reverberation.
- Flexible control of coverage angles, frequency response, and directivity through built-in DSP.
- Easily scalable by adding or removing modules to suit different venue sizes.
3. Key Technical Specifications
- SPL (Sound Pressure Level): determines output capability and maximum coverage distance.
- Coverage Angle: defines vertical and horizontal dispersion to ensure optimal area coverage.
- DSP (Digital Signal Processing): enables EQ, delay, crossover, phase alignment, and timing optimization between modules.
- Rigging: the structural system for flying or stacking modules, ensuring safety and precise aiming.
4. How to Select a Line Array System
- Evaluate venue size to determine the number of modules and required coverage angles.
- Large stages or outdoor events require higher SPL and more powerful modules.
- Indoor venues can use smaller modules with narrower coverage, making rigging and alignment easier.
- Consider DSP capabilities and compatibility with existing amplifiers and mixers.
5. Principles of Line Array Deployment & Rigging
- The top modules control long-throw coverage, while the bottom modules handle front-fill or near-field areas.
- Module angles and spacing must follow recommended design parameters to avoid destructive interference.
- Rigging systems must be rated for the correct load capacity and compliant with manufacturer safety guidelines.
