無(wú)論再好的KTV音響設(shè)備，也要調(diào)試到位才能發(fā)揮的功效。而保持穩(wěn)定，特別是終端喇叭系統(tǒng)長(zhǎng)時(shí)間連續(xù)性的穩(wěn)定工作就是一個(gè)涉及KTV利益和運(yùn)營(yíng)的大事了。
No matter how good the KTV audio equipment is, it also needs to be debugged in place to play its role. And to maintain stability, especially the long-term continuous stability of the terminal horn system, is a major event involving the interests and operation of KTV.
KTV音響設(shè)備不同于其他任何的一種音響使用場(chǎng)合，這主要是因?yàn)镵TV沒(méi)有專門的人員來(lái)操作系統(tǒng)，所以一定程度上即使好的企業(yè)恐怕也很難始終工作在佳的狀態(tài)上。所以也才會(huì)導(dǎo)致沒(méi)有燒不掉的喇叭的情況。基本上都認(rèn)為功放的功率要大于負(fù)載的2—3倍，對(duì)于一個(gè)有人員操作的系統(tǒng)，這是有必要的。但KTV系統(tǒng)這樣去配置功率那就等于埋下了地雷。當(dāng)然服務(wù)生可以把功放的輸出隔斷在一個(gè)常量上，但事實(shí)上對(duì)于那些高歌的群眾，這個(gè)常量的設(shè)置是根本滿足不了他們吶喊的欲望的。
KTV audio equipment is different from any other kind of audio application, this is mainly because KTV has no special personnel to operate the system, so to a certain extent, even a good brand is difficult to always work in a good state. That's why there's no horn that can't be burned. It is generally believed that the power of the power amplifier should be 2-3 times greater than the load, which is necessary for a system operated by professionals. But KTV system to configure power in this way is equivalent to laying a mine. Of course, the server can cut off the output of the power amplifier in a constant, but in fact, for those singing masses, the setting of this constant can not satisfy their crying desire. 淺談KTV音響設(shè)備系統(tǒng)的保養(yǎng)
Talking about the maintenance of KTV audio equipment system
建議功放的功率大于負(fù)載的1.5倍即可(一個(gè)單路輸出120W額定的功放帶了一個(gè)100W額定的PROBASSCO音箱(共40間包房)，4年沒(méi)有壞一個(gè)低音，高音(直徑45的鈦膜)緊壞了4個(gè)。當(dāng)然如果你不對(duì)喇叭單元進(jìn)行"再加工"，是達(dá)不到那樣的高能的。
It is recommended that the power of the power amplifier should be 1.5 times greater than the load (a single output 120W rated power amplifier with a 100W rated probasco speaker (a total of 40 private rooms), there is not a bad bass in 4 years, and the treble (diameter 45 titanium film) has broken 4. Of course, if you don't "reprocess" the horn unit, you can't achieve that high energy.
揚(yáng)聲器的音圈是處在懸浮狀態(tài)的，也就是說(shuō)除了定心支片與盆架有輕微接觸外，基本就再?zèng)]有用來(lái)傳導(dǎo)熱量的媒介了。所以如何讓音圈與中 心磁柱保持接觸從而限度的把熱量揮發(fā)出去是讓揚(yáng)聲器在滿符合狀態(tài)下穩(wěn)定運(yùn)行的關(guān)鍵。
The voice coil of the loudspeaker is in a suspended state, that is to say, except that the centering piece has slight contact with the basin frame, there is basically no medium for conducting heat. Therefore, how to keep the voice coil in contact with the central magnetic column to volatilize the heat is the key to make the loudspeaker operate stably under the full compliance state.
目前有在高音磁縫加注磁液的手段用來(lái)建立音圈與中 心磁柱的接觸，但在領(lǐng)域內(nèi)為了保持較高的靈敏度，往往是不這么做的。而低音單元(動(dòng)圈)目前還沒(méi)有任何手段在音圈與磁柱之間建立媒介。所以這個(gè)時(shí)候我們需要改變下態(tài)度來(lái)解決問(wèn)題。那就是因情況而易，不要被理論的框框所束縛。
At present, there is a method of filling magnetic fluid in the high pitch magnetic slot to establish the contact between the voice coil and the central magnetic column, but in order to maintain high sensitivity in the field, it is often not done so. At present, there is no means to build a medium between the voice coil and the magnetic column. So at this time, we need to change our attitude to solve the problem. That is, it's easy because of the situation. Don't be bound by the theoretical framework.
KTV音響設(shè)備系統(tǒng)其實(shí)就是一種玩具，基于這一點(diǎn)，關(guān)心的是如何讓系統(tǒng)穩(wěn)定運(yùn)行，而不要再用所謂的嚴(yán)謹(jǐn)或者發(fā)燒的態(tài)度了。其實(shí)無(wú)論是低音單元還是高音單元，都有可以實(shí)現(xiàn)音圈迅速散熱的方法，并且是簡(jiǎn)便，人人都可以做到的。通過(guò)這種方法，不僅大大的提高了揚(yáng)聲器連續(xù)音樂(lè)功率的時(shí)間，并且很明顯的改善了單元的順態(tài)特性，其整體效益遠(yuǎn)大于磁液。
KTV audio equipment system is actually a kind of toy. Based on this, what we care about is how to make the system run stably, instead of using the so-called rigorous or feverish attitude. In fact, whether it is a bass unit or a treble unit, there is a way to realize the rapid heat dissipation of voice coil, and it is simple and everyone can do it. Through this method, not only the continuous music power time of the loudspeaker is greatly improved, but also the in-line characteristics of the unit are obviously improved, and the overall benefit is far greater than that of the magnetic fluid.
