China Association senior sound engineer sound engineer Liu Hua good


article in the last period I have written before about the preparations sound PK, PK and other aspects of the process, this passage about how to better results demonstrate PK and PK issues need attention, PK and other aspects of cases. (Continue content) E, display a sound system ultimate test: First, put a little light music, the final check that all equipment is working properly, every speaker is not all have the voice, the volume is not appropriate? PK before the formal commissioning of the equipment, audio equipment, the situation is little if no major problems, but in the formal PK, the equipment if there is a little problem, will leave a bad impression to the Party, it should pay particular attention to . 2, sound system Description: When the verification system works properly, you can begin formal PK shows, a PK just like a show, since it is necessary to have an opening performance, the need for a host, so we must first to do is introduce the product first introduce our own company, showing a good image of the company; then introduce our products with features and systems, and related other information. The principal can create an opening and harmonious atmosphere, the mood ease we are all embarrassed. 3, to answer the question: general description of our finished products, the Party of the DJ and other technical staff will provide a number of related issues, our technical staff to prepare themselves well to simple and accurate answer to the question the other side. 4, microphone show: The first step is usually the next PK show the effect of the microphone, of course, except for some pure music system. a, microphone sound display: sound is simply sound good or not after listening to different sound field, different equipment, different methods and techniques to adjust the microphone will affect the sound, so we have to choose the right microphone, and not the microphone The higher the price the better. Sound display on the microphone to note no music (talking) and while there is music (singing), the two situations, there is no music when we speak of the tone generally not too high, then generally not too much bass microphone, or talking Comparison of the sound will feel nausea, unclear; but we have music concert, the sound of the pitch will be higher, the sound will become brighter more, this time on the need to increase the microphone's bass can be a little bit of treble attenuation Otherwise, we will feel when singing voice is not full weaker. This I found no notes that many manufacturers of domestic and imported brand-name Kara OK speaker feel more when we speak turbidity, nausea, but not the same feeling when singing, and that our singing and music more integration feel good. But the domestic good Duo Kala OK speaker on the contrary, when speaking feel more clear and bright, and we also complacent, sounding as: penetration and magnetic well. But when the concert is not the case when the feeling, that our singing and music confluence bad, like water and oil separation as high, while song also appears relatively sharp, the voice sounds very confused, very noisy, feel the sound is concentrated to a narrow alt band, almost no bass, treble at this time it was too tight and strident, and this sounds pretty on top of head pain heard for a long time. This phenomenon we should have a clear mind, the main reason for this phenomenon is our domestic manufacturers, or: \to the needs of the singer, psychological, and other aspects of the acoustic characteristics. Even more bizarre is that many manufacturers of domestic R & D when Kara OK speaker, is to use music as the base for positioning instead of positioning the microphone, even though some manufacturers also use a single microphone with a microphone, a small number of staff audition,kids karaoke machine, in fact, a karaoke The final speaker sounds OK we need to use a variety of microphone positioning, different voices sing again with the appropriate sound field, the professional electro-acoustic technology to adjust other aspects preceded by the details so everything. b, microphone reverb displayed: Kara OK traditional delay and echo effects are usually very long, as much reverb, so even if not a professional singer, you can easily sing, which is characterized by Kara OK located. Now, with the popularity of digital effects chip and the effect of different customers different requirements of the human voice, the traditional effect of Kara OK is not a fixed standard, and which need our sound engineer according to the characteristics of our devices, Party A's preferences, sound field conditions to flexibly adjust the reverb, reverb on the microphone to show basically no need to pay attention to music (talking) and while there is music (singing), the two situations, there is no music when we speak not to add too much reverb large, too heavy reverb tail will affect the clarity of the microphone, the sound is too small will not feel shriveled water, so transferred to moderate like; but when we have music concert, the microphone reverb would increased, the reverberation is too small dry as no water customers will think the sound was too tight, not integration degree and breadth, sing the worst, too much reverberation will not hear songs like, therefore transferred to medium . c, microphone volume display: Party A technician may be holding the microphone near the speakers we test whether the back under the microphone input, this point of the Party is no doubt a test of a good or bad sound the easiest, most direct approach. However, our technical people to completely avoid the transfusion phenomenon is very difficult, not the technology not work because the box equipment are generally too simple, no way to further adjustments of the technology have no place to use are really can not make bricks without straw Yeah. If some private rooms equipped with multi-segment graphic equalizer, then we can look back to find the equalizer output point of frequency, these look like some frequency attenuation, but the problem is now much better box with a multi-channel sound reinforcement system with sound, it is called civil is: 5.1 or 7.1 system, then we can not give each channel are configured equalizer, right? In fact there is a bass whistle issue is a long time haunt us, we know that if HI is necessary to have sound systems in the subwoofer, that if customers have to sing it? Before the bass volume is the first off, or the microphone may have a very strong bass transfusion, the last analog device to completely solve this problem is difficult, but we mentioned in previous articles in the latest U.S. ETC FC-3 series KTV digital processing before the class on perfect solution to this problem, FC-3 with 5.1 channel output, which sang bass channel volume can adjust the volume, its principle is to use the microphone volume as a trigger level, and level with high, medium, low three options, triggered automatically after the bass attenuation, attenuation range from 0% to 100% of the option, so when the bass singing the volume can be adjusted according to our set up, but also can avoid the perfect bass reinfusion ; FC-3 other main channel, in the home, such as five-channel surround sound volume can be controlled separately, the microphone sound and musical sound can be built-in stereo through the 31 professional digital equalizer to adjust the available essential to prevent transfusion phenomenon, this device can also be connected to your computer through the RS232 interface, and then run on a computer random distribution of professional audio processing software, so that we can be more intuitive and the various parameters of the device adjust the good results The document also can be stored to facilitate future data recovery. With this equipment, we can resolve the contradictions they sing and HI, and also good to avoid the transfusion phenomenon, the voice of the microphone also can be opened to the great, at least in the microphone's volume terms, Party A will feel more satisfaction, and this is key to the success of PK. 5 music display: In a certain sense, in all of Kara OK, music is the subsidiary status, the microphone sound is the main character, display of music basically pay attention to when no microphone and microphone when the two situation, there is no microphone system purely music-based HI or slow wave, all the adjustments this time around how to better demonstrate the effect of music-based; When the microphone, the music of the adjustment was more flexible, Live music is not the time to grab the microphone and the frequency, we can let the microphone volume bigger than the music volume, while the high frequency part of the equalizer can be centered on the relevance to 4KHz frequency attenuation about, so the music will not alt too bright, people can better highlight the high-frequency sound. When the above is to demonstrate the effect of the basic elements of music, display the following details are specific: a, soft music to show: more soft music may well demonstrate the speaker's level of sense of sophistication, resolution and so on, where to Note that the choice of music is better, but also to adjust the warmth of the rich sound, smooth bright but subtle not play it have carried away listening to people, people intoxicated, intoxicated feeling, special attention is that Music careful that the tone, not volume, so the signal level before the speaker volume level and can not greatly, but the volume is too small the system will be easier to highlight the local noise, the sound volume too will become relatively rigid, but does not conform to the atmosphere of soft music, and the volume is too large will make people nervous can not relax, then do not say what people intoxicated. b, loud music display: HI Housing and slow now shaking the music room are mostly relatively strong, so the music can well demonstrate the speaker's level of sense of strength, speed of response, dynamic range, we also have Note that a good choice of music, HI room to adjust the low frequency sound strong, strong shock, alt to be loud and penetrating, with a sense of rhythm, combined with larger sound pressure level, so the music can be a good stimulus the nervous, people can not help but be involved with the madness and music. First of all, this music is about sound pressure level, there is not enough volume, no matter how perfect you can not sound exciting, so before adjusting the signal level and speaker-level volume can be larger, so is well to demonstrate the music and the whole dynamic range of sound, but at this time should be taken to avoid distortion of signal and speakers; slow roll music although the music is strong, but still has its unique characteristics, slowly shaking music to adjust the low frequency fullness, not bear not hard, not too noisy alt round. To make people feel comfortable listening to this music, like massage, just like with your eyes closed and enjoy rocking slowly, slowly shaking the music both have a large sound pressure level but also has good sound, so adjust the time before level and speaker level signals can be sufficiently large volume of some. c, an integrated music display: comprehensive music can be a good show overall performance of speaker power, balance, layered, dynamic range, low frequency of such music to adjust to the fullness and intensity are all good,home karaoke machine, alt To adjust the brightness, degree of superb round. To have more people listening to exciting, progressive, happy feeling, not like soft music as people intoxicated and do not like loud music and crazy exciting, just in between. Pay attention to this kind of music is sound good, moderate volume, the same former level and speaker level signals to be moderate volume also we go. Medium-intensity signal and the speaker volume level can take into account both the dynamic range and intensity of the music, sound blunt but also to avoid the phenomenon. 6, Live Performance show: even the best equipment, no matter how good the acoustics are serving others, is to do when we PK between devices and can communicate well, so listen, or try out our equipment, people Our audio equipment have feelings, following my experience that some of the details of the interpretation of these: a, if the pure music sound system, then do not show the effect of the microphone, we can own the first CD-player with some better music, selecting music to be full time attention to the bass strong sense of rhythm, do not use too fast for the music, because if the PK field acoustic is not good, fast music will be very active reflection, it is easy to become noisy. Party may also provide a number of CD discs, then we should pay attention to determine the types and characteristics of these music and quickly adjust our equipment; with CD show finished, will be asked to play some of the general Party VOD computer music, if VOD system is our own, we are relatively good operating point, if Party A VOD system, then we should observe and listen, try to adjust our equipment. VOD systems are generally compressed audio files, compressed music treble part of the performance is not good, the music seems not enough width, and penetration levels are not feeling well, so the music we first should be fine computer audio output of the level, slightly larger increase in the electric Lotion is the dynamic range of music VOD, enhanced strength and penetrating power of music, right layering and a broad rating of help, but should pay attention to distortion problems, computer sound card out The voice is easy to distortion. In short now show nothing more than pure music discs and VOD several computer systems, the key is the scene of the flexible operation. b, In the case of microphone-based audio systems, we adjust the microphone in addition to other effects, the best singing but also have good staff to show our own conditions, then the PK can get some professional singers, of course, can also train themselves one start interpretations Party officers will not be too active audition, need our own people get to sing two songs active of atmosphere, then Party A person may begin to sing before, we need to note that as far as possible Click the fast songs, to avoid the cold field. Party officials in concert, we should observe and listen to their views, in accordance with the requirements of the sound and then they look perfect. In short this process needs to our people, Party people, audio equipment, can interactions among them, an atmosphere of active point as far as possible, so have a good sound system, there has been singing good staff, the overall PK results will not be too bad, at least give a good impression Party. c, sing and HI if the sound system, then we refer to the above two kinds of systems integration adjusted, show good attention to the microphone when singing the effect of music belongs to a secondary location at this time, not too prominent; in the show music effect, we will not be back at the microphone input to ensure the case can be music-based, enjoy the music, and show good results. Of course, these need our sound engineer has a good mix of skills Caixing. F, PK when PK after the end of the work, whether successful or not, we have to do some follow-up work: 1, to seek the Party's views on our products, while our own staff said that under the Party and the time of our PK performance of their own to a conclusion under the PK, but anyway, PK after the end of our most basic courtesy and etiquette can not lose, because we represent the company's image and demeanor, which would also facilitate the future and the Party continue to maintain good communication. 2, if the Party of the equipment we need to listen again to stay a few days, then we have to run the relevant procedures, and then look for the DJ and manager of such Party leader, let them protect the safety equipment issues; if do not need to audition to stay, then we need rapid removal of equipment packing removed. 3, if the Party does not oppose us have time, we can go after PK observe what other companies PK process, from which sum up the advantages of others, but also his own PK effects and others to do some comparison. 4, the last of our business, and public relations officers should continue to make human relations, technical staff and the Party should be good communication between the technical staff. Left to do is wait for the Party's decision, and as long as we do when a PK force, success or failure is go with the flow of. 3, audio PK issues that need attention like a war as a PK or a performance, so in order to ensure victory and the success of performance, we need to be careful everywhere, in general we have to pay attention to the following questions: 1, product testing and burn machine: PK ago, we had better equipment before the need to link PK to see that not all normal, because the truth is really made of professional audio equipment is not absolutely sure that no problems, advance testing is necessary; if a new device, you can burn off the plane first, so the sound is not as stiff as new machines. 2, power supply: we must bring enough power outlet, some long enough, enough to power the power cord, because the Party of the PK site power system may also be confused, we need to own the power system buttoned. 3, wire preparation: we have to take a good variety of possible use of the signal line and a variety of signal connectors on the signal line length and number should be enough, but also bring electric iron and other wiring tool just in case. 4, the system noise: Party of the PK field is generally not a good ground, and our equipment can not ground, then the sound system in the noise would have been very obvious, particularly VOD VOD system computer computer equipment because of static, easy to generate significant noise. Therefore, we display results in the period, in the absence of music, sound volume will not open too much, otherwise it will highlight the background noise out; when there are music, music signals can mask out of this noise. If the noise is large, we can not connect first VOD system, the signal line, wait until the connection when the need arises. It should be noted that there is a good contact with the microphone cable is also very susceptible to noise. 5, PK display order: In view of the characteristics of the human ear, we must first show when PK is the microphone of the sound and relatively soft music, the last to show relatively strong, large sound pressure level of the music. If the opposite case, when the first demonstrated in the PK is relatively strong, large sound pressure level of the music, the ear of the alt then we will reduce the sensitivity, listen to the speaker, sound, music and more gentle voice, that voice will be dry Baba's, a little magnetic and penetration are not. We must pay attention to this small trick. 6, Party A special hobby: We recognize the sound, Party not authorized, so you: a good customer that is really good! Likened our sound engineer in the Royal Palace kitchen, we adjust the sound out as cook the food, the emperor said that good eating it OK, well, then re-do, is not a cook out of food will make All people are saying right? So we sound engineer to be flexible according to the requirements of Party A to adjust our sound. Several cases of PK: 1, a company in the PK of a project, the Party basically satisfied, and said device a few days left to re-audition settle down, the result after a few days, said Party not good, they go found that the equipment connected to the people into confusion, there are two speakers in the treble also burned up, and asked Party officials said they do not know how happened, in fact, this is a typical interpersonal problems. 2, a hotel audio PK, every company must display a large box and the effect of a small box, A box where products performed well in the big boss also more recognition, so let Party A company first went to install a small sound box, so go small box next audition, but requested song A computer system, the first company to stay, and let the company borrow the second B, because it was very hot inside the box, Party DJ in order to save time and speed up PK speed, put A, B system integration companies use. A company's performance, but not very match, although it seems that left song system, but the B company found that this VOD system are special needs A company's technical staff to operate a bit but no way A company like that to help competition rival service, the result is buck-passing, a lot of wasted time, and finally Party boss angry, A company can move equipment, leave a small box would not have tried. 3, there is a 5.1 channel system requirements PK Party to require use of a single 18-inch bass speaker, but there is a company with the two pairs of 15-inch subwoofer to the effect, of course Well, other companies do not think fair, Party DJ directly to that company said: \4, a friend on a project in Tianjin, Party requested is as simple as the sound is large enough, not like back to lose. Most companies are more or less to the PK of the equipment to do the treble attenuation, so of course reduce the treble of the transfusion, because the Party boss of the listening level of the general, thinking that you can muddle through. My friend's product is better, technology is also very good, their equipment and not opportunistic decay treble, then they look to the Party boss reflects the unfair practices of other companies, the boss again carefully listened to each one sound effects, final spot closed device with my friends, mainly the company that my friend is, of course, equipment is really good. 5, there are times A, B PK a project the two companies, A company's products more prominent midrange, but the treble is not enough width; B's audio frequency response is wide, bright treble frequency smoothing, the actual results should be better than the A's. But party bosses with big ears on the treble part of the less sensitive but it does feel good effect of A company, that company B sound a bit noisy. B company was put audio division increased treble attenuation Alto more, in full accordance with the requirements of the Party bosses and listening habits to the tune, eventually won the project. PK said above, when several cases of success and failures of the case. On how well we can better demonstrate the audio equipment, so that PK success, which many factors, no standard methods and procedures, our article because of space constraints we can only write so many, in fact, if we can do to: \Our equipment and technical staff is very professional; the course of our PK is very attentive, and our attitude is sincere, we are all to the interests Party. In summary the results of PK Party is to know our company attaches great importance to this project, and on the PK is concerned, our company has extensive construction experience, we have been focused on audio industry and the entertainment industry's latest developments, I believe We can perfect a series of projects to complete Party! This on the \content, We hope you help! As limited, inevitably inadequate, but also hope you lots of peers and experts, correct me!
