A line array PA system is a key element in the advanced design and technology of large events as it provides clear enriched sound quality. Broad dispersion line array speaker system uses multiple vertical arrays in order to provide even sound distribution throughout wider areas. A system like the JBL VTX A8 line array, which stretches arrays of 12 inch low-frequency drivers and 1.5-inch high frequency driver up to audiences as large as nearly half a football field soccer fields with consistent clarity throughout the crowd.
By getting sound further out into the crowd, the line array configuration gets rid of phase or distortion as well increases coverage with advanced waveguide technology. The array also angles each speaker depending on its position to make sure the sound wave will perfectly converge in that space, limiting the problem of focusing and coverage. With this design, it can give its listener an accurate sound reproduction for up to 150 feet away and is normally used in big outdoor festivals or stadium events.
This type of PA system can be expensive to invest in depending upon size and features, with prices ranging between $30,000-$100,000 for a line array. The cost of this setup is offset by the superior sound that can be broadcasted to some larger audiences with little interference or feedback. One good example is the Meyer Sound LYON line array system- a great choice for major events and concerts, that can cost around $75.000 full spec's installed!
Because it is a scalable approach line array systems can be deployed to suit different event sizes and applications. A lot of them are modular, with the ability to add more units in parallell if you need anything larger. This being important for events that can be as small 50 and others clocking in at over 1500.
If you have ever been to a Super Bowl or big-time music festival, there is high probability line array PA systems were used. For instance, the 2023 Coachella Music Festival employed the L-Acoustics K1 line array system to deliver pristine audio for tens of thousands festivalgoers in numerous stage-centered scenarios.
When it comes to large events, the deployment of a line array pa system will improve audio quality and bring consistent coverage throughout an event space while reducing distortion – so a highly recommended option for major productions and in larger spaces.
