The term "Line Array​" is used to describe a loudspeaker system that has multiple loudspeaker units with the same characteristics arranged vertically to simulate a linear sound source. Sound propagating from line array speakers has very little dispersion in the vertical plane compared to standard loudspeakers operating as points, sources where the sound travels with wide dispersion angles in the horizontal and vertical planes. Therefore, the attenuation of sound pressure with distance is small.

With the development of the economic and cultural level and the rapid growth of people's spiritual life needs, the performance market is very active. Various indoor concerts, theater performances, outdoor concerts, and large-scale TV variety shows are welcomed by the masses.

When setting up a Line Array system, one of the most critical aspects of the process is ensuring that the speaker's audio can be heard no matter where the audience is seated. Compare that to a concert of your favorite music act. You may not have the best view of the stage, but you'll likely be able to hear the music no matter where you sit.

Actual sound reinforcement occasions include many large halls, venues, outdoor open-air stages, etc., and the live environment and audience positions are different. This needs to be applied to the acoustic characteristics of Line Array​s of different shapes. Including straight line sound sources, arc sound sources, J-type sound sources, progressive sound sources, etc.

The line array​ speaker system has been widely developed and applied at home and abroad in recent years, and it appears in large-scale sports games and large-scale performances with its unique advantages. It can almost be said that no speaker manufacturing company does not produce line array speakers.

The sound reinforcement system is a system that amplifies the voice of the performer in real-time and transmits it to the listener. Performers and listeners are usually in the same acoustic environment. Line Array must meet the needs of users during the design process, and design the sound structure so that it can cover the entire venue step by step and clearly.
