KTV Literacy Category
Entertainment City's private rooms are no less than the following categories: 1. Quantitative version of karaoke (KTV) room; 2. Nightclub karaoke room (nightclub room); 3. Multi-functional karaoke room (Hi room); 4. Restaurant karaoke room (RTV room). If there is no young lady who can only sing in a studio, it can be called a KTV room for sale according to the time and time of opening a room; if there is a young lady, it can be called a nightclub room with a higher charge, and the nightclub room generally sets * consumption, that is, as long as the guest chooses the type of room to enter the room, he must at least consume the prescribed amount, and if he exceeds * consumption, he will receive additional income; if he plays dancing music as the main part, he will also play dancing music as the main part. Singing karaoke, each room must have an ultra-bass speaker, can loudly shock, so that guests can jump madly in the room, called multi-functional Hi room, referred to as Hi room; while providing restaurant restaurants and karaoke services for RTV room.
Usually because of the low price of volume-selling KTV, people think that it is the lower grade of these types of houses. However, due to different regions and different consumption power, KTV rooms also have high, medium and low-grade differences, nightclubs also have high, medium and low-grade, Hi and RTV rooms are the same. So we can't * say that the sound in the nightclub room is definitely better than that in the KTV room.
How to configure the private room audio
First of all, we should start with the selection and confirmation of speakers. The most important thing to remember is that the sensitivity and power allocation of the speaker in the private room are the key to the system allocation - because the power allocation of the amplifier is larger than the rated power of the speaker, so the power of the speaker is determined before the basic basis for the power allocation of the amplifier is established.
The sensitivity and power of the speaker are two important scientific and objective indicators, which determine the sound pressure level (sound responsiveness) of the enclosure sound. The high-power speaker can open loudly but stably and safely, while the low-power speaker may burn out when it opens loudly.
The speaker with high sensitivity has high efficiency, easy to push, low power consumption and low distortion. The speaker with low sensitivity is not easy to push. When it emits sound with the same sound pressure level as the speaker with high sensitivity, it consumes a lot of power and distortion of power amplifier. The speakers with high sensitivity, high power and relatively large sound pressure have the advantages of high efficiency, high sound pressure and stability and durability.
The power of the amplifier should be between 1.3 and 2.5 times larger than the rated power of the speaker, because if the power of the amplifier is large enough, the sound of the speaker will be full, strong and dynamic enough. If the power is not large enough, the low frequency performance of the speaker will be poor, and the sound will feel very virtual. And power amplifier power shortage is more likely to burn the horn.
The room space and sound absorption coefficient will consume power, so the safe and reasonable sound box power required should be calculated according to the room space volume. After determining the sound box power, the power amplifier should be allocated according to the principle of 1.3-2.5 times, and the level of the power amplifier should be selected according to the investment budget. Like power amplifiers, speakers can be priced at a considerable distance at the same power but at different levels.
Usually, a pair of speakers above 135 watts is enough for a compartment under 15 square meters; a pair of speakers above 180 watts for a compartment below 20 square meters; and a pair of speakers below 30 square meters for a room below 270 watts. As long as it is not a Hi room, theoretically every square metre is equipped with more than 18 watts of power (speaker power).
If it is a Hi room, as Hi passengers enter the state, they need louder and more shocking sound effects to stimulate the sensory nerves, and they need to be equipped with greater power. Moreover, because Hi room sound is generally continuous high power, loud pressure, fast rhythm, long time in the limit state of work, so the speaker must also be anti-fatigue, durable varieties.
Experienced engineers with many years of engineering design conclude that professional Hi rooms should be equipped with at least 25 watts of full-frequency professional speaker power and 40 watts of ultra-bass power per square meter. Otherwise, not only the sound effect meets the needs of Hi, but also the stability is questionable.
In terms of speakers' characteristics, the KTV speaker (foam edge bass and bass pitched high pitched voice) has good sound elasticity and wide coverage. It is suitable for use in KTV, nightclubs and RTV rooms that are not very large and close to each other, and is not suitable for use in professional Hi rooms.
Professional speakers (cloth bass plus horn treble) sound strong, horn characteristics make high-pitch directivity too strong, high-pitch than two-frequency KTV speaker is brighter and clearer, but the sound elasticity is less than KTV speaker. In addition, if there is no proper sound absorption or diffusion design in the room after the horn improves the mid-treble energy, it is easy to produce mid-treble local excessive intensity, which is relatively easy to cause screams (commonly known as Feimi) in the compartment of short distance and small space, so the gain and loss should be fully considered before configuring.
No matter what kind of private rooms, high-quality sound is the guarantee of grade style and practical effect. Although the technicians can make the sound effect relatively better by debugging, if the "base" of the sound is very poor, no matter how good the tuning technology can make a fundamental change in the sound quality and timbre effect. What is a high-quality sound? Subjectively speaking, "good singing, good listening and durable" is a high-quality sound. The standard of "good singing" is probably easier to reach agreement. Everyone may know that good singing is not good as long as he picks up the microphone and sings a few times. The criterion of "good-listening" has always been different among different people and wise people for reasons of region, nationality, race, culture and living background, so it can only be said that what most people agree with is good. "Durability" refers to: objectively tested power, high sensitivity, can meet long-term, large dynamic, loud pressure, long-term stable and safe use.
