【 Weak current College 】 KTV acoustics design--device configuration article

Karaoke as KTV's major business content, it has been created by sound effects and KTV rooms, service, drinks, etc. into a product, a KTV operators and KTV audio equipment production factories, distributors, contractors and DJ were the focus of attention. So when it comes to product is because KTV sound effects from the common development of personality trend, we know that the sound effects are used to describe the characteristics, cannot be simple with good or bad to outline, KTV sound and stage audio, home audio, Hi-Fi has a very big difference: a designated area of KTV audio to get the target consumer group of the largest identity, to form a regional culture, with a consumption habits of consumers, need KTV audio designers and investors to make a rational decision, does not copy the so-called successful experiences.
KTV acoustics design contains audio device configuration, package room decoration, private room furniture selection, audio equipment, audio equipment parameter settings, and several other aspects of the content.
KTV audio equipment, configuration combinations also many, many devices in best match is a project that is currently known,-till the KTV is doing most of the ordinary KTV operators is very difficult to have the opportunity to do so, I personally think that the selection of experienced professional engineering KTV more easily achieve their objectives. KTV professional contractors is a specialized organization for KTV project, it may also be some long-term employment experience of the experts, they have to KTV sound insights, and even to make the best of KTV audio, painstaking research, resulting in a sleepless night. I would like to pay tribute to these predecessors, admire their professionalism and KTV audio efforts and contributions. Crap, KTV audio device configuration direction about eight characters: sing ' comfortable, listeners, or said that singing comfortably, listening to the weather. Is eight along… We went from the eight characters to analyze KTV audio configuration.
Traditional karaoke merge-amplifier of the price-performance, feature complete, affordable, contains karaoke singing all the facilities needed: audio and video switching, music movements, music with original songs, music tones, multi-channel microphone mixing amplifier, microphone, microphone echo effects, pitch control, volume control, microphone total volume control, music master volume control, infrared remote control, power amplifiers, etc., because the machine functions and limitations of the machine body, the theory of power are within, of course, practical 180W power best to 80W-150W. This type of karaoke amplifier classic when pushing PioneerSA-V210, commonly known as the pioneer in 210, is a master as unsurpassable masterpiece, expert analysis, pioneer 210 cannot be copied and transcendent due mainly to the components, the 1980s transistor and IC production technology features make pioneer's soft features 210. As a point through sound know-how: audio equipment to play or play sound timbre depends on components. It also gave the KTV karaoke amplifier uniqueness made a note, KTV karaoke amplifier is between professional and fever between States.
KTV sound of another important part is the speaker, speaker, commonly known as card package is karaoke rooms speakers. Card Pack speaker from karaoke appear to present a basic form did not change, in accordance with the evolution of karaoke can be divided into the BMB, PRODIO, YAMAHA brand of several classic kuanxing, I don't think BOSE301 type is karaoke box, you can sing karaoke, was not designed. Karaoke speaker BMBCS-450V is classic, yet to see beyond its works, its design is the most simple, all on a few trumpet in the output, no complex divider. Karaoke speaker to play with the expressiveness of the human voice and the best combination of music, in large dynamic music voice will still be able to stand out is BMBCS-450V strength.
YAMAHA's Karaoke speaker is familiar in Taiwan-till kuanxing, a master of redefining the karaoke sound sector presented a completely new concept of KTV audio. Medicine-till package room decoration and private room furniture design complement each other, creating a KTV audio myth. -Till sound has its independent character, contains-till business philosophy, whether you like it or not,-till is-till, there are many guests pay. Not to mention the till, YAMAHA's this karaoke speaker has many sound idea integration, multi-angle treble projection bring small space range more real natural reverberation, highly desirable, the voice timbre expression full orientation of delicate and not real, circle, point mentioning musical expression. Moreover, YAMAHA this speaker adaptation, totally need decoration as well as professional sound amplifying equipment around, more need high technology management level, in addition to the application of the till has always been a bit confused acclimatized.
PRODIO very early to the concept of projection angle in a high-pitched, perhaps inspired by the BOSE is unknown, but it shows the flexibility of the Chinese people, it's treble not only more free rotation angle, admire admire. Do not know because there is no personality or marketing is ineffective, PRODIO always failed to create brilliant market.
KTV audio configuration microphone choice is very important, early in the project developers like to use a professional microphone SHURE, stage, until recently, only to realize professional karaoke microphone, karaoke microphone property requires net head wear resitance, straps durable resistance to wear, switch, wire fortitude, is the most basic requirement, most importantly karaoke microphone must not easy feedback whistling (fly mark), but also to optimize the human voice in particular, the excess attenuation on the voice-frequency and high frequency, high-frequency in the voice of the more prominent, so-called easy. -Till early in the put this concept into the industry, through another excellent factory custom fit-till private room acoustics microphone audio header, and continuously upgrade update, in order to perfect. Ability to configure their own audio equipment to customize microphone KTV in addition to an estimated no-till. A good KTV microphone is actually not the handset tone head manufacturers leading the development ofIs perhaps because the developer is very difficult to understand the needs of timbre, in a fortuitous tests, there are some handset tone head happens to be some master, my friend, Bole race horses. Unfortunately, these codes head technology like Horn, are difficult to replicate the same becomes the master secret weapon, and removing the external never revealed their middle. About classic is to understand the KTV audio development. KTV audio device configuration to grasp for power amplifier, speakers, microphone, the three elements mentioned earlier also, no matter what changes the configuration form, or you are within range.
KTV amplifier selection. KTV amplifier into merge-karaoke amplifier as well as combinations of pre-and grade separation, according to the microphone effect type is divided into traditional ECHO and DSP. In fact, traditional ECHO is early DSP processor, limited to the technical requirements and cost control, performance is not high, the application scope is more limited. Early design of merge-karaoke amplifier power is generally smaller and accompanying speaker is a sensitivity higher low-power speaker, the most likely problem is feedback whistling (fly mark), is due to the large volume of work is insufficient power reserves, causing serious distortion, coupled with the high sensitivity of the speaker is distorted feedback, distortion caused by circular zoom, feedback whistling (fly mark).
In principle, grant-Whistler (fly mark) is the main cause of the distortion, reduce distortion can reduce feedback whistling (fly mark) chance, but it cannot be said that no feedback whistling (fly mark) that can only be described within the scope of available gain, gain sufficient age can also cause feedback whistling (fly mark). In other words, KTV karaoke amplifier to select power. However, the larger the amplifier's power, the more hard timbre feel, through the actual experience of each channel 8 Ω 300 W or less can be selected. Select power amplifier and speaker mix is important, speaker impedance, sensitivity and power will influence the choice of the amplifier, the general principle is the high sensitivity of the sound power corresponding with smaller, amplifier power 2 x speaker power, sensitivity and low power of the speaker, the corresponding with large power amplifier power 2.5 ~ 3 times the power of sound, this configuration is relatively stable. Amplifier's timbre is the most difficult to identify, not words can express, this is also the most difficult part is to enable manufacturers to be able to survive, reproducing the world it is difficult to have absolute Kings, the whole is personal understanding and choice. Less than 18 m² rooms are basically a well-designed traditional ECHO effect karaoke amplifier competency. However, for the business management needs, when you put the sound effect as a product to treat, traditional ECHO will create sound effects uncertainty, each guest of debugging requirements may let administrators never effect determines the location of the unity, also will let DJ became exhausted.
Use with DSP processor power amplifier of the second reason is that traditional ECHO effect processing chip frequency response range narrow (less than 8KHz), the sampling frequency is low, at the request of high-power output becomes cloudy, cannot play far, penetrating enough. While DSP as high as the sampling frequency and 48K 20Hz ~ 23KHz broadband response range brings clearer sound with better penetration in high frequency. Use with DSP processor power amplifier of the third reason is that the DSP effects processor can store multiple results data, bringing real available Reverb-"Reverb" effect, give consumers more sing K experience truly consumer self-service K songs, but also significantly reduces the DJ service requirements, plus VOD system effect automatically initialize function rooms of sound effects to deliver consistent levels.
Just say, 18 m² of package room if simple evaluation of timbre, a well-designed traditional ECHO effect does not lose to DSP effects, but seems thick and soft, is a bit DSP digital flavor is too strong, flexible enough, if DSP LPF to place both contrast 8Khz more evident, the main difference in thickness of the part of the low frequency.
Merge-karaoke amplifier with front and rear level split with the main application of choice of room types seeing actual demand, 18 square meters within the room it is recommended that you choose a 200W or DSP merge-karaoke amplifier; 18 square meters above to 25 square meters room type you can choose three channel 200W of DSP karaoke amplifier to increase Central speaker for sound treble voices fill; more than 25 square meters or more rooms will have to consider using separate collocation, before and after class based on the actual shape of specific room types, the main considerations of sound pressure level, sound field uniformity, mixed sound field in the main building, after the level of sound power amplifier with speaker features to choose the right power-assisted power speakers can use multi-channel low power after the class amplifier to reduce costs.
KTV room speaker selection is divided into the main speaker and auxiliary speaker, private room speaker evaluation is expressive of the human voice, the sound you want to highlight the phase you want (listen to see if you can send out the human voice, the voice of the speaker will feel back in the box), music frequency response to wide, dynamic enough, may wish to find a selection of BMB450 to contrast, the closest wins would not be wrong. Package room speaker selection is also based on the target consumer group of consumption to determine that the major cities of karaoke consumer consumption concept more mature, and the entertainment category of smaller, basically can not consider or rarely consider the k-and compatibility, see HI investor market positioning, pure K key voice expressive and 8 "subwoofer unit speaker of the human voice expressive best, 10" bass unit of music will sound much better, somewhat less human voice.
Tertiary-level city of mass entertainment market started relatively late, consumers of karaoke consumption concept fuzzy, basic view KTV is mentally relaxing place, need to sing also need DISCO, more in need HI, the situation around. On the compatibility of requirements to 10 "bass unit speaker, best use of low sensitivity, this comparison can be put to the test design.
More than 45 square meter large room, generally need to use more than 12 "bass unit for speaker, so performance price is quite high, and, of course, install a many-to-8" or 10 "speakers plus a secondary low-frequency speaker can also have different characteristics, mainly see investmentAnd target requirements. Many-to-8 "or 10" speakers are expressed, the human voice would be more flexible, music surround are better, but the sound pressure level is not enough, dynamic enough, for pure K design is acceptable. 12 "or 15" speakers generally Horn high tone, sound pressure level, dynamic range, also, the disadvantage is that the human voice has left, of course, designed specifically for KTV 12 "or 15" speakers will also have good performance. Use the 12 "or 15" speaker for major speakers generally also need to configure a secondary speaker, auxiliary speaker does not exceed 8 "is appropriate, it is best to increase the frequency to meet the primary speaker line timbre.
KTV room microphone selection method is commonplace, it is possible to pick out a lot in preparing some microphone options, different size and decor of the rooms willuse different types of microphones, as mentioned, the best selection of KTV professionally designed microphone. An audition to find various age groups of men and women singers to test evaluation. For a different speaker amplifier with a different microphone matching, mainly in the field test.
