Principles and advantages and disadvantages of line array speakers
With the development of the times, the corresponding audio is also developing rapidly. Among the many audio systems currently on the market, linear array speaker systems have appeared in many large-scale sports games and large-scale performances around the world. So what is line array audio, what are its advantages and disadvantages, and what is the principle? The following editor will introduce you to one or two. Linear array What is a linear array? A linear array is a group of radiating elements arranged in a straight line and closely spaced, and have the same amplitude and phase. Although they are arranged in a straight line, the coverage angle is different. The concept of linear arrays is not unique today. It was originally proposed by American acoustics expert H.F Olson. In 1957, Olson published the classic acoustic monograph "Acoustical Engineering" (Acoustical Engineering), discussing that linear arrays are particularly suitable for long-range acoustic radiation. This is because linear arrays can provide very good directivity of vertical coverage to achieve good acoustic results.早期 The early linear array speaker system appeared in the 1970s, but it was incomplete. In the form of a "sound wall". Dozens or even hundreds of speakers are stacked horizontally and vertically to form a sound wall. When the power of 10,000 watts is turned on, it really shakes the mountain and has an extraordinary momentum. But people quickly discovered its shortcomings. Not only do they need too many speakers, but also the interference between speakers makes the sound quality worse, and the directivity and coverage are affected. At the European AES Conference in 1983, Philips introduced the concept of a Bessel function matrix using a simple weighting factor to solve this problem. However, to manufacture Bessel arrays, a license must be obtained from Philips and a corresponding price must be paid. It is interesting that companies using linear array loudspeakers are silent about Bessel arrays. The current linear array speaker system has been fully improved, and it is not the same as the early days. It is also quite practical in structure. For example, dozens of boxes can be assembled, hung, and wired within one hour, and put into use immediately.

What are the three key elements of stage sound effects?
In recent years, with the improvement of the level of material civilization, audiences have higher requirements for auditory experience. Whether it is watching art performances or enjoying music programs, they hope to get better artistic enjoyment. The role of stage sound effects in performances has become increasingly prominent, and people have gradually paid attention to them. How to optimize the sound effect of the stage is a problem that every literary and art group must consider. This article starts with the three key elements of "tuning quality of stage tuner, combination of audio equipment, and integration of sound and stage environment. How to optimize stage sound effects. Grasp the overall stage 1 The tuner should have professional tuning quality * Voice actor Zhang Guilan said well: "The actor's language performing arts and the sound artist's debugging art are the relationship between scales and puppets." "The sound actually debugged is not the actor's original sound, but the sound engineer's transformation through the sound equipment. "Passed sound", it can be seen that the tuning quality of a tuner directly affects the effect of stage sound, and then the quality of the entire stage performance. For this reason, the stage tuner should have professional tuning quality. 01 Has good sound debugging technology As a tuner, we must deeply analyze and understand the commissioned musical works, and combine electro-acoustic technology and acoustic technology well. For example, use the equalizer to improve the sound of the original sound; use the reverb and delay to increase the sense of intimacy, distance and space; you can also use the "double" technology to increase the "group feeling" of a certain instrument; especially now With the adoption of digital audio technology, the tuner can modify the sound waves to create the sound of human voices and musical instruments. According to the characteristics of the voices of different actors, they can highlight the advantages of their voices and make up for their sound weaknesses, such as reverberation in male solo. The intensity should be lowered, and the female singer's solo reverb intensity should be adjusted higher, which will make the singing better. Only by mastering the requirements of different types of stage performance sounds can the tuner grasp the overall situation of the stage and call up the stage sound effects. 02 Have good acoustic art 良好 Tuner's good acoustic art accomplishment directly affects the stage sound debugging effect. The tuner should be familiar with the differences between the performance of different actors, different instruments, and the vibration frequency and harmonics of the sounding material. Familiar with the narrow bandwidth of various instruments and human voices can identify the characteristics and defects of the sound. If a singer sings on the stage with MIDI accompaniment, the tuner handles his accompaniment. Similarly, the music that comes with a pleasing dance is handled by the tuner. At this time, the stage requires the tuner to apply the strong and weak contrast of the music to the stage performance to make it echo, in order to achieve the perfect performance. 03 Possesses good psychological quality for audio debugging Facts have proved that the psychological quality of the tuner has a great relationship with the sound effects of the stage. The instability of the psychological emotions will cause the tuner's hearing sensitivity and resolution to decline, and even the inability to judge various sounds correctly will bring the entire stage effect. Negative impact. To this end, the tuner must master the necessary psychological knowledge, cultivate strong psychological adaptability, psychological endurance and psychological regulation ability, and on this basis, make good use of artistic psychology, creative psychology, audience psychology Knowledge can organically combine the seriousness and solemnity of music with the humor of music in order to improve one's overall taste and level in stage audio work. Selected audio equipment 2 Ensure professional level of audio equipment combination With the development of the times, modern audiences have higher requirements for the stage, not only to satisfy the visual pleasure, but also to complete the aesthetic process of hearing. Therefore, in order to fully optimize the sound effect of the stage, one of the key factors is to carefully choose the sound equipment. Stage sound system is a combination of signal source equipment, signal processing equipment, power amplifier and speakers, etc., through tuning by the tuner to achieve a good stage sound effect. 01 Ensure professional sound equipment configuration Sound equipment is an important foundation for ensuring the sound effect of the stage. It is directly related to the success and failure of stage art presentation. The frequency range of microphone power amplifiers and speakers is very important. At
