Features of line array audio

With the development of science and technology, the corresponding sound equipment is also in rapid development. Among the numerous sound systems in the market, linear array speaker system has appeared in many large gymnasiums and large performance sites in the world.

What is line array

Linear array is a group of radiation elements arranged in a straight line and closely spaced, and has the same amplitude and phase. Although it is arranged in a straight line, the coverage is arranged at different angles, and the linear array can provide very good directivity of the vertical coverage to achieve good acoustic effect.

In recent years, the linear array loudspeaker system is made up of several loudspeakers overlapped in the vertical plane, forming a certain horizontal angle (generally 90). ）Narrow beam in vertical direction. An outdoor sports field (the distance can be more than 100m), with such four linear array systems can meet the requirements of sound field coverage, which is the advantage of linear array system. Linear array systems often have a slight bend. The purpose is to get a larger coverage angle. The main part is for the far field and the curved part is for the near field. Because of the asymmetry of the vertical directivity, some sound energy can be gathered in the part with insufficient high frequency.

In general, the characteristics of linear array are as follows:

1. In the vertical plane of the main axis, the directivity is narrow beam, and the energy superposition can radiate for a long distance. The lower end of the curved part of the linear column covers the near area, forming the near and far coverage.

2. The improvement of linear array sound reinforcement box is more in line with the requirements of technology, process and installation.

3. The disadvantage is that the linear array itself does not improve the sound quality, so we can not completely remove the mutual interference, only try to reduce the interference.

The linear array sound system has the characteristics of long-distance radiation near and far coverage, convenient installation and so on. These characteristics make the linear array sound system suitable for bars, banquet halls, multi-functional report halls, large opera houses and gymnasiums and other sound reinforcement places.
