Line array audio is a speaker system, and its technology and manufacturing process have been developing steadily for many years. Recently, the situation has changed, and linear array speaker systems have appeared in many large-scale sports events and large-scale performances around the world.
A linear array is a group of radiating elements arranged in a straight line and closely spaced with the same amplitude and phase. Because of the same phase, the speakers and speakers are closely spaced. A set of line arrays can be thought of as a single speaker.
In the performance or large-area long-distance sound reinforcement, the number of listeners is often hundreds or thousands of people, so the power of the current pair of speakers is far from the power required for listening. Therefore, in such a sound reinforcement place, several pairs or more speakers are often used to form a speaker wall, which is called a speaker matrix. However, such a matrix, because of the different phases, some frequencies in the speaker will interfere, which seriously affects the restoration of the sound. Therefore, the birth of the wired array speaker.
The advantages of a linear array sound system are obvious.
(1) Due to the characteristics of the linear array, the directivity of the vertical plane of the main axis is a narrow beam, and the energy superposition can be radiated from a long distance. The lower end of the curved portion of the linear column covers the near region, forming a cover from near to far.
(2) The improvement of the linear array sound reinforcement box is more in line with the requirements of technology, process and installation.
