Although good speakers can be suitable for most occasions, there is still a difference between entertainment city private room speakers and commercial performance speakers.
Today’s private room speakers are generally mainly used for karaoke singing functions, although there are also some Hi-room speakers that are mainly used for listening to dance music (the fabric-edged bass increases the power to drive the horn-type tweeter) Professional large box), but you must also be able to Hi and sing.
For high-end private rooms, speakers must be selected with clean sound quality, distinct listening sense, bright and clear, rich details, soft and elastic. Because the space in the private room is relatively small and the seats are close to the speakers, if the sound quality of the speakers is rough, it will be harsh, making people unable to sit in the room for a long time, and conversation and communication will be very difficult.
As far as two-way KTV speakers with foam-sided bass and paper cone treble are concerned, 8-inch and 6-and-a-half-inch speakers sing relatively well. Speaker units of this caliber have relatively sufficient mid-frequency energy and are more capable. It highlights the human voice, but the single-bass 8-inch and 6-and-a-half-inch speakers have low power and can only satisfy a small room.
If the room has a large space and you feel that the bass of the music is not deep and full enough, you can add a subwoofer. However, it is best not to let the human voice (microphone sound) enter the subwoofer box, because the human voice after being amplified by the subwoofer will be thick, but it lacks the mellow and bright realism, and becomes not clear enough and penetrating, making people sing. You will feel out of breath when singing. In addition, if the human voice (microphone sound) enters the subwoofer, the low frequency may also howl (commonly known as flying microphone), and the low frequency howling may cause the bass unit to "retire" early.
If it is a three-way KTV speaker or a professional speaker, 8-inch, 10-inch, and 12-inch speakers are all good for singing. Professional speakers have good transients and crisp rhythm performance, but the sound is relatively hard to hear. The horn's treble has strong directivity and relatively narrow coverage. It is easy to cause howling when used in private rooms with strong reflections. Therefore, it is usually only suitable for use in large rooms, and a subwoofer is usually added to make up for the lack of flexibility and increase surround. feel.
As far as sound is concerned, the primary pursuit of pure karaoke room audio is bright, clear, and natural sound. Because the sound of the speakers is bright, clear, and natural, singing can be relaxed and comfortable. The vast majority of people are not professional singers, and their voices may not be very strong even if they have an average voice. Therefore, it is very important to sing easily - people can only sing without exerting too much effort but can hear their own voices more clearly and loudly. Only when you are satisfied can your mood rise, and your desire to sing and perform will be stronger.
In addition, bright and clear sound is of great significance to KTV speakers, because the bright and clear sound is positioned forward, has a sense of presence, makes people feel warm, friendly, and easy to listen to. excited. Bright and clear timbre is also of great significance to the Hi Room. According to hearsay, bright, clear and natural timbre can make some guests "see" wonderful things, while dim timbre can make people "see" or think of ugly and terrifying scenes. and things make people unhappy when playing with them, and may even cause trouble.
In practice, since the sound pressure in the Hi room is extremely high, the mids and highs of the speakers can be slightly suppressed, sacrificing a little brightness of the music, and increasing a little softness and durability of the music, so that guests can enjoy the music. It is not too strenuous to talk and communicate in the room, and you can enjoy the fun of "talking over wine, pushing glasses and changing glasses" in the room.
For karaoke rooms, the KTV integrated power amplifier is best to use double reverberation, because if the two reverberation effects can be adjusted reasonably, singing will be easier, and if the two-channel reverberation is used Okay, you can widen the sound field and highlight the sense of space.
It is best for the KTV amplifier to have adjustable mid-range, because after suppressing some of the mid-range and high-pitched sounds of the music, the music will become relatively softer, making the microphone vocals clearer, brighter and more prominent, and also Satisfy those who like soft music. Whether it is a combined power amplifier or a professional power amplifier, clean, balanced and stable sound is the first choice. Usually the power of the power amplifier should be between 1.3 and 2.5 times greater than the rated power of the speaker.
The power of Hi room speakers and amplifiers must be sufficient, because the working conditions of Hi room speakers and karaoke room speakers are very different:
First, each karaoke song Generally, only about two-thirds of the songs have strong low-frequency rhythm sounds, but in dance music (Hi songs), almost the entire song has strong low-frequency rhythm sounds.
Secondly, the average karaoke song has about 90 beats per minute, while the dance music has about 120 beats per minute or more. When the power amplifier's electric energy is applied to the speaker to convert it into sound energy, the paper cone and bounce wave of the woofer will move back and forth once for each beat of music rhythm. Therefore, Hi room speakers must use high-stability products that can withstand high power, high dynamics, and long-term use. Professional speakers are the first choice.
Most people only pursue the "shocky and loud" effect, which can be solved by using ordinary professional speakers. People with high requirements will like the sound effect that is "shocky and loud, but bright, clear, soft, natural and not harsh" and allows people to "chat easily". Therefore, the professional speakers selected for high-demand Hi rooms have higher performance and quality.
As an investor, it is right to choose a speaker that is "shocky and loud, but bright, clear, soft, natural and not harsh" and allows people to "chat easily". Because if the sound is loud but harsh and makes conversation very laborious, the guests in the room will lose the fun of "changing glasses, drinking wine, and having fun". Without these fun, the sales of wine will be greatly reduced, and investment will be greatly reduced. The benefits are naturally greatly reduced!
If the speaker is loud but the sound quality is not good, or even harsh and noisy, and people have to exert all their strength to speak a word before they can barely hear the meaning clearly, then the speaker is holding his breath. It can also be embarrassing and frustrating for people listening to other people talk.
Whether it is a Hi room or a karaoke room, elastic and enveloping sound effects are definitely the best choice. If the sound is hard, like a "punch to the flesh" hitting someone on the chest or face, young people can play with it, but people of a certain age and with spending power should not be able to sit in the room for a long time.
The sound of good speakers is bright, clear and natural. In addition to the above performance, better speakers will have a more layered feeling, as if the sound is surrounding people from all directions, allowing people to hear more musical elements and sound details, and feel the bright, clear and soft sound in the room. The entire space is diffuse and convergent, with a wide sound field, a strong sense of space, presence and envelopment, and full flexibility.
The sound from a bad speaker seems to be twisted together and rushing towards people's heads and faces. Although the sound seems "clean", it always lacks a lot of sound details, and the loud sound makes people feel harsh. The back is retracted, dry and flat, hard and dull.
In addition to the sound quality and timbre of speakers in entertainment venues, they must meet certain standards and their power must be high. Because of its high power, it can withstand tossing and rough use, making it relatively more stable and durable.
Sensitivity is one of the important indicators of speakers. Speakers with high sensitivity are easy to push. Therefore, when the sound is natural, choose a speaker with relatively large power, relatively high sensitivity, relatively wide frequency response, and a relatively more balanced curve. The speakers are correct.
The power of the power amplifier must be greater than the rated power of the speaker, otherwise it will not be able to show the calm and majestic momentum of a good speaker, and insufficient power of the power amplifier will be more harmful to the stability of the speaker. When a good amplifier is paired with a good speaker, the sound quality is clean and natural, usually giving people a more moist, transparent, and layered listening experience, while when a poor amplifier is paired with a bad speaker, the sound is rough, dull, soulless, and noisy in the background. Heavy, in practical use, it will make the sound unclean and make people irritated.
A good preamp is specially developed for high-end private room audio equipment. It can replace a lot of equipment such as mixers, effectors, crossovers, equalizers, etc., and even provides stimulation and feedback. Functions such as suppression are a powerful tuning tool for private room audio, and are also the most effective guarantee of private room sound quality. A good speaker is like chicken, and a good preamplifier is like salt. No matter how good the chicken is, its taste will be affected if it lacks salt or improperly adds salt. It can't be too good.
At present, there are analog and digital DSP preamps.
The sound of the analog preamplifier is more real and natural than the digital one, and people have listened to and sang it for many years, so it has a mass base and a large number of loyal fans; the DSP preamplifier is more powerful and highly adjustable. , but it also places higher demands on users’ skills.
If the private room uses a DSP digital preamplifier, the adjustability will be stronger. If it is adjusted well, the music will sound better, the singing will be natural and relaxed, and there will be more choices for sound field modes, and multiple ones can be adjusted. Sound fields and reverberation modes with different effects are stored and recalled at any time to meet the different preferences and needs of different customer groups.
The microphone should be chosen with appropriate sensitivity, bright, clear, real and natural tone, otherwise those who can sing will not sing well, and those who cannot sing will sing even worse. Although the microphone may be the cheapest in the system, it is the only equipment for picking up human voices. If not selected properly, it will directly ruin the high-end audio equipment and become a fly in the ointment.
Engineering experts should communicate more with owners, adjust tones and effects that local people love according to the requirements of investors, turn decay into magic, and ultimately reflect the value and significance of technology. Similarly, the relevant person in charge of the investor should also take the initiative to communicate more with the sound company's sound technicians, and tell the sound technicians the effect needs of their own venue or local people, so that they can have a clear direction for effect debugging. If they don't understand it at all, It doesn’t matter how you express it, you just need to bring the tuning technician to a KTV room that you think is good, and feel the effect of listening and singing together. Those tuning technicians with skills, feelings and understanding will definitely be able to satisfy you. need.
The choice of speakers is one thing, and the actual application is another. How to adjust and use the equipment well so that everyone is happy, full communication is an important foundation.
