The difference between the three types of entertainment audio

　　Do you know which entertainment speakers are different? Today, the editor will take you to know the different occasions of entertainment audio and the difference between different audios.

　　Mass-sold KTV based on singing:

　　First of all, when dealing with the average degree of the sound field in the room (it won't feel too noisy, but the sound pressure is acceptable), when multiple speakers are sounding, the main speakers use front- or rear-oriented speakers to achieve better low-frequency restoration (according to the actual situation of the venue). to select).

　　In addition, the most important point is the processing of singing effect dyeing, that is to use DSP digital effects to beautify the human voice, use stereo effect processing: add some height, expand the sound field, and then use HPF (high-pass filter circuit) to increase the lips and teeth to make the singing sound more It is magnetic, in a word, it beautifies the voice of the singer, so that customers feel that "singing in this store, the voice of singing is much better than your own voice".

　　Therefore, the requirements for the equipment here are not for the purpose of restoring the original sound, but how to beautify the sound. If this direction is not properly grasped, a considerable proportion of guests may be dissatisfied in future business use (mainly because the singing of ordinary guests is not necessarily so good), and the pursuit of high restoration is the wrong direction.

　　The guests who come to the business nightclub are generally for business entertainment, and the other is to find a place to relax with three or five friends; in order to achieve the purpose of enjoying the guests and the host, it is inevitable to have a lively drink, but the hearing will be reduced after drinking: Therefore, the requirements for sound pressure will be larger than that of pure singing KTV.

　　And after three rounds of drinking, it is the kind of heroic sound that is like a bell, not delicate and gentle; at this time, the speakers are mostly direct-firing speakers. Depending on the size of the room, choose a speaker with enough sound pressure level, and the power of the power amplifier should keep up. In addition, if the room is too large, special attention should be paid to the distance between the speaker position and the seating area. Otherwise, if the distance is too far, the singer's sense of self-listening will be much worse.

　　Pay attention to the best projection distance of the speaker you choose. Only by choosing the speaker reasonably can you achieve the purpose of playing music and singing well. Reasonable installation of the speaker position can reduce howling, so that the volume of the microphone can be increased and there is more room for adjustment; and most of the nightclubs in this form use wireless microphones, and guests often walk around the room with the microphone, so how to solve the howling is a problem. Important considerations when choosing equipment. When matching, you can ask the equipment provider or the project engineer to ask about the howling solution (it is best to conduct field equipment tests).

　　The HI room nightclub that mainly plays music:

　　This type of nightclub must first pay attention to the sound source, and retain the access port of the external DJ mixer, which is convenient for professional DJs and equipment to enter the room to play discs and play music. Its sound requirements: the treble should have penetrating power (most of which use horn treble), the mid-low frequency should strengthen the dynamic performance (add equalization or audio processor), and the bass should have the feeling of sound pressure hitting the chest and abdomen (bass unit and power amplifier). choice is important).

　　The overall difficulty lies in how to achieve the effect of sound pressure, but not too loud. This starts from the selection level of the equipment. If the selection is wrong, it will occur: when the volume is turned on to the point where you feel satisfied, the sound pressure is already so large that the building materials in the room vibrate, and people can basically not talk to each other. When decorating this type of room, special attention should be paid to the sound insulation of the room and the solid installation of the ceiling and wooden decoration parts.

　　It is understood that most users and even engineering companies do not understand that mass-selling KTV, business KTV and HI room audio equipment should be distinguished in different situations, and they have been confused when selecting equipment at the beginning; I feel why my carefully selected equipment is not as good as others.

　　In fact, it's just a mistake in style and positioning, just like dressing: you should wear formal clothes when you attend a wedding, get together with friends, you can relax and so on. No matter how good-looking the clothes are, they naturally look awkward if they don't match the occasion. Therefore, the device selection should first determine the user's future use.

　　The elements to be understood after determining the type of use are as follows:

　　①The size of the private room

　　②The height of the room

　　③ Local singing habits (normal singing or shouting)

　　④ How many decibels Z is suitable for the local total volume requirement

　　⑤ The requirements for bass are not high
