What audio equipment does the special audio for large-scale concerts include?

Sound is very important for concerts, and there are usually special sound equipment. The special audio for large-scale concert mainly includes a set of power amplifier and peripheral equipment (including voltage limiter, effect device, equalizer, VCD, DVD, etc. ), speakers (speakers, speakers), mixers, microphones, display devices, etc. Among them, speakers are sound output devices, speakers, subwoofers and so on. The sound box includes three kinds of speakers, high, low, medium, three but not necessarily three. The development history of technology

It can be divided into four stages: electron tube, transistor, integrated circuit and field effect tube. ?

Features of special audio for large-scale concerts:?

1. The special acoustics for large concerts have good directivity. Generally, the speaker composed of traditional speakers has poor directivity, so you must stand in front of the speaker to hear more perfect sound, especially the high-pitched part; And if you stand on the side of the speaker, you may not hear some background or accompaniment sounds; If you stand on the back of the speaker, maybe that sweet song has become a voice you don't want to enjoy. However, flat panel speakers do not have the above problems. No matter where you stand, you can enjoy the complete and true sound. ?

2. The sound attenuation of the dedicated stereo is small. Traditional speakers, if you get too close, you will find that the sound is very loud, and if you are farther away, you will feel that the sound is much smaller. Flat panel speakers do not have the above problems. Whether in a short distance or a short distance, there is not much difference in the sound you hear. ?

3. Large-scale concerts have high fidelity. Usually, the shape of a traditional horn is a sound cone. When it vibrates to make sound, it tends to concentrate the sound in the throat, compress it, and then spread it out. What people hear is the sound of compression deformation. Flat speakers will not have the above problems, just because people have heard too many distorted sounds before, so once they come into contact with flat speakers, they will feel very ordinary at first, but later they will often be deeply attracted by its natural performance.
