The application of common line array system

The application of common line array system

The line array product here is the line array speaker of the general brand which is the most widely used in the small and medium activities in China. Because mature line array products will have relatively complete system technology to support applications, including specialized analog software, specified DSP processing, convenient control programs, and other auxiliary tools for installation, while only speakers, amplifiers, and processors in relatively low end manufacturers. How can you use such a system?

Are there any auxiliary programs suitable for this kind of wire array loudspeaker, which can at least accomplish a relatively good angle design and sound pressure coverage task?

In the process of working, I have also touched a lot of such activities. In order to facilitate their own convenience, a small Excel program is designed to easily calculate the projection angle of this type of linear array loudspeaker and the sound pressure coverage of the single body in the axis of the target area. Then the longitudinal distance point and the axial pressure distribution can be roughly measured. In order to design the array angle in a feasible range, the sound pressure distribution can not be very uniform, but the relative difference will not be very large, to a certain extent, it can improve the efficiency of your type of linear array speaker.

The program has been revised several times. It should be 1.3 edition. The new version added the position shift of the speaker single in the J array, which makes the axial projection more accurate. At the same time, we add the -3dBCross points covering the middle line between the two arrays of the system design, which are all beneficial to the optimization of the field system. The following is a partial screenshot of the program:

This article received many friends' positive response after the public platform was released. Here, I would like to express my sincere thanks to you for your support and love for PAES. At the beginning of the public platform opening, we hope that the teachers in the industry can continue to pay attention to us. With your strong support, we will do better.

The purpose of this paper is to get more people who use ordinary wire array speakers to get a relatively scientific and convenient simulation program for the linear array speaker system, to avoid the blind application of the line array, which is also out of personal experience in the actual work.

Because the program is a complete Excel format, it is not a R & D Engineer, completely out of practical experience and a combination of theoretical design ideas, after a period of time in practical application of repeated verification, the final completion of the 1.3 version. Most of the computation involved in the program is not a very profound mathematical and professional acoustic formula, but the calculation is quite varied, and the calculation is put into practical application. It is done by manual combined with calculator. The result must be unpaid and insane. Note the public number and add to my WeChat friend's experience that we really need such a procedure.

Here is to explain that the program is not a commercial product, so, we do not provide a separate sale of the program, but also against anyone to get the program, as a commercial product sales! Because of the limited level of the developer, there are some problems in the program, and the following will continue to update the program. In the future, more new data will be added to provide more in-depth acoustic data reference in the field application.

In order to get people to get this program, to a certain degree of understanding of its design principles, and so that it can be better used, we plan to focus on a group of people who need it first, through a speed training of the PAES center, through the understanding and communication during the training period, we can also get real feedback from everyone. After that, give the program to friends who participate in speed training, which can avoid the waste or blind use of the program to a certain extent.

Friends who are interested in the program, please pay attention to the public platform first.

Pay attention to and enter the public number and reply to the following contents:

Name, micro signal, cell phone number, mailbox, city in the area, office, position, and brand, model and quantity of current cable array speaker.

After receiving the reply information, as your reservation information unified record, then there will be a questionnaire to everyone, if in the 5 days after the issue of the questionnaire did not receive your answer, we will consider to automatically give up this speed training, after the questionnaire statistics, we will refer to the results of the answer, and finally confirm compliance with the requirements. The 20 places, then, inform you of the specific time, location, and related expenses (the cost will be determined by the communication of the final list, including the travel expenses and the training expenses).
