Explanation of Line Array and Speaker Placement

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.

Explanation of the line array

At present, a lot of experience has been accumulated in the design, production, and use of Line Arrays, and the understanding of line array speakers is also deepening.

Referring to Olson's theory, the definition and optimization of the line array speaker system are as follows: a group of loudspeaker units arranged in a straight line (or approximately a straight line), closely spaced, with the same amplitude (same caliber and same type), and the same phase, and A system composed of corresponding structural parts and having certain special pointing characteristics.

(1) The actual line array is slightly curved and not arranged in a straight line, so an approximately straight line is added.

(2) There are high-frequency, intermediate-frequency, and low-frequency speakers in the line array, and the amplitudes of the three cannot be the same. With the same caliber and the same type, it is rigorous.

(3) In the line array speaker system, its structural parts, cabinets, etc. are indispensable, and they are also indispensable for a complete definition.

(4) Proposed "has some special directional characteristics", which explained the characteristics and functions of the line array.

Speaker placement

The main speakers are the heart of the sound reinforcement system. According to the size of the performance venue, the main speakers should be placed on both sides of the stage entrance, facing the audience. Avoid obstacles in the middle of the sound transmission channel, radiate the sound directly to the audience area, and reduce the loss during sound transmission. Line array speakers should be tilted downward when hanging so that the tweeter points to the middle of the listening area. And it should be tilted inward at a small angle, usually between 10° and 30°, so that the speakers can radiate more evenly. The distance between the Line Array speaker and the rear wall should be more than 1 m. This distance can reduce the low-frequency "rumble" sound caused by excessive bass reflex. In the near field and the far field, the role of the line array is completely different. The near field is an interference field. When two linear arrays are close together, more and more frequency components are lost.

Sometimes due to reasons such as the venue, the line array speakers cannot be hung. In this case, it is necessary to consider the deployment method of stacking on the ground. Because the bass is non-directional and has strong penetrating power, it is necessary to consider placing the subwoofer on the stage plane or concrete floor, granite, carpet, etc., so that the bass has a sense of rolling from the ground.
