Linear array sound is a group of closely spaced radiation units arranged in a straight line with the same amplitude and phase. It is mainly applicable to large mobile performances, stadiums, multi-function lecture halls, large theaters and other occasions. The demand for linear array sound varies from place size to place size. No matter how the place is, the biggest purpose of linear series is not only to enable all audiences to hear uniform sound, but also to maintain high sound fidelity.

The linear array speaker system is composed of several speakers overlapped in the vertical plane to form a certain horizontal angle (generally 90) Narrow beam in the vertical direction. For an outdoor sports field (the distance can be more than 100m), such four linear array systems are sufficient to meet the requirements of sound field coverage, which is the advantage of linear array systems. Linear array systems often have a slight bend in order to obtain a greater coverage angle. The main part is for the far field, and the bending part is for the near field. Asymmetrical vertical directivity can gather some sound energy in the part with insufficient high frequency.

It has uniform coverage and good diffusion. Due to the characteristics of linear array, the directivity in the vertical plane of the main axis is narrow, and the energy superposition can radiate in a long distance. The lower end of the bending part of the linear column covers the near area, forming a cover from near to far. And the improvement of linear array sound reinforcement box is more in line with the requirements of technology, process and installation.

When designing and installing a set of conference audio equipment, it is inevitable to encounter the matching problem between conference power amplifier and audio. In terms of timbre, we will pay attention to whether the collocation is appropriate and moderate. From the technical point of view, the elements of conference power amplifier and audio are: power matching, impedance matching, damping coefficient matching. If we realize the above points when matching, the performance of all equipment can be fully and greatly exerted.
