無論再好的KTV音響設備，也要調試到位才能發揮的功效。而保持穩定，特別是終端喇叭系統長時間連續性的穩定工作就是一個涉及KTV利益和運營的大事了。
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音響設備不同于其他任何的一種音響使用場合，這主要是因為KTV沒有專門的人員來操作系統，所以一定程度上即使好的企業恐怕也很難始終工作在佳的狀態上。所以也才會導致沒有燒不掉的喇叭的情況。基本上都認為功放的功率要大于負載的2—3倍，對于一個有人員操作的系統，這是有必要的。但KTV系統這樣去配置功率那就等于埋下了地雷。當然服務生可以把功放的輸出隔斷在一個常量上，但事實上對于那些高歌的群眾，這個常量的設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音響設備系統的保養
Talking about the maintenance of KTV audio equipment system
建議功放的功率大于負載的1.5倍即可(一個單路輸出120W額定的功放帶了一個100W額定的PROBASSCO音箱(共40間包房)，4年沒有壞一個低音，高音(直徑45的鈦膜)緊壞了4個。當然如果你不對喇叭單元進行"再加工"，是達不到那樣的高能的。
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.
揚聲器的音圈是處在懸浮狀態的，也就是說除了定心支片與盆架有輕微接觸外，基本就再沒有用來傳導熱量的媒介了。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出去是讓揚聲器在滿符合狀態下穩定運行的關鍵。
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建立音圈與中 心磁柱的接觸，但在領域內為了保持較高的靈敏度，往往是不這么做的。而低音單元(動圈)目前還沒有任何手段在音圈與磁柱之間建立媒介。所以這個時候我們需要改變下態度來解決問題。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音響設備系統其實就是一種玩具，基于這一點，關心的是如何讓系統穩定運行，而不要再用所謂的嚴謹或者發燒的態度了。其實無論是低音單元還是高音單元，都有可以實現音圈迅速散熱的方法，并且是簡便，人人都可以做到的。通過這種方法，不僅大大的提高了揚聲器連續音樂功率的時間，并且很明顯的改善了單元的順態特性，其整體效益遠大于磁液。
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.
