In recent years, there have been more and more entertainment programs, the application range of audio equipment has become more and more extensive, and the requirements for speakers have become higher and higher. The appearance of line array speakers has met people's needs. Because of its good directionality, the line array speaker system provides uniform sound field, small sound interference of sound field, and good sound quality, which is very popular among musicians.
How does line array speaker attract more audio enthusiasts with its outstanding advantages?
1) Regular arrangement of individual speakers, easy installation and hanging
The line array speaker system consists of a single column of speakers. These individual speakers are arranged according to certain specifications and can be arranged in a straight line and a "J" shape according to the sound field requirements.
Line array speaker systems generally have dedicated hanging devices, each with a special hook designed to control the deflection angle of a single speaker as needed. Therefore, it is very convenient to assemble and hang on site.
2) Power is large and the projection distance is long.
For example, the low-frequency unit in the LA-212 single speaker is capable of 750W, sensitivity 107db; high-frequency unit power 180W, sensitivity 114db.
After a single speaker is formed into an array, the radiation resistance of the speaker is improved due to the interaction between the individual speakers, and the radiation efficiency is improved. Therefore, it is a breeze to obtain a sound pressure level of 100 db or more outside the 100 m using the line array speaker system as a sound source.
5) Small unwanted reflections
In the debugging process of the sound reinforcement system, the most troublesome is: the interference of the reflected sound. It may interfere with the direct sound, making the sound unclear. The directivity control capability of the line array is stronger than that of the general speaker, the radiated sound energy is small, and the interference to the sound field is small.
6）Line array speaker built-in DSP module
Line array speakers have built-in amplifiers and DSP processors. It can adjust delay, equalization, pressure limits and other parameters via the USB interface. After debugging, the speaker can be used directly by connecting the signal cable and the power cable. Due to the built-in amplifier circuit, it is not necessary to consider the problem of matching the speaker to the amplifier and the troublesome wiring problem. The fusion between the frequency bands is natural and smooth, and the high frequency is well extended, delicate and supple.
The line array speaker system is a new terminal in the sound reinforcement system, and is a new product combining high-tech and traditional electro-acoustic transducers. But to achieve the desired radiation field and listening effects, there are still many problems that need to be studied and solved. Sinbosen Audio specializes in the production of line array audio, single ten inch, double ten inch, single twelve inch, double twelve inch, double fifteen inch line array speaker can meet the needs of a variety of large, medium and small occasions.

3)Uniform coverage and good diffusion.
Due to the nature of the linear array, the directivity of the vertical plane of the main axis is a narrow beam and the energy can be superimposed from a long distance. The lower end of the curved portion of the linear column covers the vicinity to form a coverage from near to far. Direct sound dominates the area with good listening, clear sound and high resolution.
4) Good frequency characteristics.
The average line array has a frequency of 50-16 kHz, and some are even wider. For example, the frequency of the KA208 line array is at 40Hz-20KHz. Since the high frequency is easily attenuated when the sound wave propagates in the air, the high frequency is often not heard by the remote audition. However, the line array is different from the conventional speaker, and the high frequency is carefully designed and compensated to ensure good high frequency characteristics for long distance coverage.
