In the field of modern sound engineering, line array (Line Array) systems have become the preferred sound solution for large-scale events and professional venues due to their superior sound quality and coverage capabilities. In this paper, we will discuss in depth the basic concept of line arrays, working principle and its application in audio engineering.

Modern Line Arrays use separate drivers for the high-frequency, mid-frequency, and low-frequency passbands. For a line source to work, the drivers in each passband need to be aligned. Therefore, each enclosure must be designed to fit tightly together to form a column of high-frequency, midrange, and low-frequency speaker drivers.

The development of professional audio is changing with each passing day, and Line Array System has become the mainstream of the market in just a few years, and it shines brilliantly in fixed installation projects and various performances.

When the line array​ speaker system is suspended, there are various forms according to the structure of the array and the actual sound reproduction requirements. The common forms are linear, arc, and so on.

To reasonably configure the power amplifier and speakers, two issues must first be clarified, one is the natural properties of the music signal, and the other is the nature of the output power of the power amplifier.

Line Arrays are popular for their unique sound radiation characteristics. Line Array​ has the advantages of a uniform sound field, long radiation distance, large output power, and controllable directivity, and has been widely used at home and abroad in the past ten years.
