A line array is a loudspeaker system that is made using a number of usually identical loudspeaker elements mounted in a line and fed in phase, to make a near-line source of sound. As the time goes, line array speakers have steadily become the protagonist of sound reinforcement speakers. In several large stadiums and large performance venues in the world, line array speaker systems - line array speaker system has appeared. Line array speakers can also be used in multi-function halls, theaters, conference rooms, performing arts scenes, indoor and outdoor large-scale evening parties, wedding performances, large stadiums, lecture halls, etc.
Advantages of using array speaker system
- Its coverage is average and the dispersion is excellent. Due to the characteristics of the linear array, the vertical directivity of the main axis is a narrow beam, and the energy superposition can emit long-distance. And the lower end of the zigzag part of the linear column covers the near area, forming coverage from near to far.
- The improvement of the linear array loudspeaker is more in line with the necessities of craftsmanship, technology, and installation.
- The sound pressure level is huge. The directivity of the linear array becomes sharper as the frequency reduces. When it reaches a certain frequency, such as 2kHz, the directivity is radial, that is, the directivity diagram presents lobes. During this time, the sound wave generator formed by the high-frequency loudspeaker will function, so that the high frequency directivity is superimposed and improved.
- Strong directivity. The difference between the far and near fields is little.
It is a series of loudspeakers that covers the same frequency range and is stacked on top of one another. The key to a line array is that the speakers face somewhat different vertical angles, enabling them to constantly cover a greater depth of field than a single PA speaker can. There are three main types of loudspeaker to think about: line array, point source, and column array.
Line array speaker system is ideal for big events or outdoor concerts as they can reach a larger area with clear and consistent sound. As they can be controlled, you can do clever things with them like create 'exclusion zones' or pay attention to the sound into a specific area of the venue. Because line arrays need multiple boxes to do what they do, every good speaker manufacturer will tell you that you have to have a minimum 4 cells together to get any benefit.
