济南音响系统中的喇叭常有烧掉或破声的情形，一般人直觉人会认为是开太大声了喇叭会受不了，因而把喇叭弄坏，其实不然，有许多种情况都可能，分别举例如下面的情况及理由，相信可以有助于您维护喇叭长寿数十岁。
The sound system of Ji'nan in the horn often burned or fractured situation, general intuition will think it's too loud horn will not stand, thus the horn break, in fact, there are many kinds of conditions may, respectively, as the following examples and reasons, believe that can help you maintain the long dozens of horn years old.
我们经常使用麦克风演讲或唱歌的会因为麦克风靠喇叭太近或对着喇叭，开大音量产生高频正回授的啸声，这一下您的喇叭高音单体可能就不灵了。这是因为中高音一经分音器之后大部的信号都从高音发出，这种高能量的信号全数通过圈极细的高音单体就把喇叭烧了，所以常您用麦克风时，千万记得音量由至大慢慢加，别一口气开大，免得喇叭只发出像牛声般的低频。
We often use a microphone speech or singing because microphone near the horn too close or at the horn, turn up the volume produce Gao Pinzheng feedback howling, this horn tweeter you might not work. This is because the Alt a after crossovers signal department are sent from the treble, treble monomer such high energy signal all through the circle of very fine put the horn to burn, so often you use the microphone, remember to add volume by slowly, don't sigh open, lest the horn only emit low-frequency sound like like cattle.
1、开太大声固然会振坏喇叭，另一种情况就是扩大机功率不足硬开大声，所输出的都是不正常的切割信号，这种情况也会把喇叭损坏。建议喜好大音量的使用者要选购大功率的扩大机，30W的小功率后级极可能烧掉低阻抗大喇叭的。
1, too loud while it would shatter the horn, another is to expand the machine power less than hard up, the output is cutting signal is not normal, this will put the horn damage. Expanding machine suggest preferences large volume users to buy high power, low power 30W level after is very likely to burn low impedance loudspeaker.
2、扩大机如果有直流输出，那一定会烧掉低音喇叭，甚至极少数的高音喇叭也会烧掉。原因乃低音(或其他音路)喇叭分音路径上没有电容器隔离直流，直流一输出就像把直流电通入喇叭中，连分音器线圈一起烧得焦黑。因此选购扩大机时千万注意，要先用电表测量前级和后级的输出端是否有直流输出，如果前级有直流输出也有可能经由后级再放大输出把直流传入喇叭。
2, expand the machine if there is a direct current output, it will burn the bass horn, even a handful of loudspeakers can burn. The reason is the bass (or other sound Road) loudspeakers no Capacitor DC isolation sound path, DC output like the direct current into the horn, even split voice coil with charred. Therefore choose to expand machine must pay attention to, first with the output level meter front stage and back end whether DC output, if the front stage DC outputs is also possible via the level is amplified and output to DC incoming speaker.
3、如果您是自己装的它手一定知道高频振荡这回事，假如您现在也在自己装，那更要请注意高频振荡，最好用示波器检查一下前级和后级是否有振荡或直流输出，万一您没有发现有此状况，那也许烧掉您高级的喇叭够让您买好几部20MHz的示波器了。
3, if you are a pretended it hands must know that the high frequency oscillation, if you also now in their own equipment, it is more to note the high frequency oscillation, it is best to use an oscilloscope to check the front stage and back stage whether oscillations or DC output, in case you have not found this situation, it may burn your senior horn is enough to make you buy a few 20MHz oscillograph.
有输出变压器的真空管后级(或广播用的)不会有直流输出的(如果有就吓人了)，但是真空管机又流行起来了，要特别注意真空管机比较容易有高频振荡或干扰，上述的情况是喇叭最常发生的原因，提供你作为日常保养的参考。
Vacuum with an output transformer tube after the class (or broadcasts) there will be no DC output (if there is scary), but the vacuum tube machine again, special attention should be paid to the vacuum tube machine easier to have a high frequency oscillation or interference, the situation is the most frequent reason horn, provided you as the daily maintenance of the reference.
济南音响器材重搭配，阴阳要调和 我一直强调，器材的搭配的重要性远胜于单独器材本身的好坏。便宜的器材如果得到适当的搭配，其表现一定会胜过搭配不良的高价器材而器材搭配的原则就是找到平衡点，就像翘翘板般，找到中间的那个平衡点。基于此因，如果个性阳刚的器材我们就找阴柔的来配，让它的个性听起来很顺。如果觉得音色太亮的器材我们就找温暖的来配;速度太慢的我们就为它配上速度快者。
Ji'nan audio equipment heavy collocation, to reconcile the Yin and Yang I have always stressed, equipment collocation is far more important than the individual equipment itself is good or bad. Cheap equipment if properly matched, its performance will certainly better than the high price of equipment and equipment with the poor matching principle is to find a balance point, like a seesaw like, find the balance point in the middle. Based on this result, if personality masculine equipment we find feminine personality to match, let it sounds very smooth. If feel the timbre too bright equipment we find warm to match; too slow for it with our fast.
总之，阴阳调和、刚柔并济，找到平衡的声音是大原则。 电源弄乾净，清静透明有层次，身处都市公寓丛林里，我们家里充满各种电子干扰污染。不管是从电源线传来的(马达转动、日光灯闪烁)，空气中传来的(射频干扰，电磁干扰)都让我们无法逃避。为了减少这些干扰，我们尽量做到冰箱、冷气、除湿机、洗衣机等有马达的电气回路不要与音响的回路在一起。
In short, to reconcile the Yin and Yang, rigid flexible and economic, find the balance is the voice of principles. Power clean, quiet and transparent layers, in a city apartment in the jungle, our home is full of all kinds of electronic jamming pollution. No matter is to preach the power line (from the motor to rotate, fluorescent lamp flicker), air came (radio frequency interference, electromagnetic interference) are so that we can not escape. In order to reduce the interference, we try to do the refrigerator, air-conditioning, dehumidifier, washing machine motor electrical circuit not and sound of the loop together.
如果能拉条济南音响 http://www.jnzqyx.com/ 专用电源当然更好。室内如果能够不用日光灯就尽量不用，调光器也会产生杂讯。此外，市面上有卖一些抗电磁与射频干扰的小道具，也有各种电源滤波器、处理器等可以选用。 如何判别自己的电源弄乾净了呢?很简单，电源越乾净，声音听起来就越清楚、安静、透明，而且层次感会越好。
If special power brace Ji'nan sound better of course. Indoor fluorescent lamp without if can do as much as possible, dimmer will produce noise. In addition, sell some anti electromagnetic and radio frequency interference props on the market, there are all kinds of power supply filter, a processor can be selected. How to determine its own power to get clean? Very simple, supply more clean, sound more clear, An Jing, transparent, and sense of hierarchy will be better.
不过有一点要特别注意，以前很多人越处理声音越瘦，到最后只剩下清楚而乾乾的中音、瘦瘦的中音与不够丰润的低音，这是不对的。正确的声音应该是高音水水甜甜的，中音饱满丰满，低音量足又有弹性。 接头勤拂拭，线头要锁紧，所谓接头就是讯号输入输出的接头。这些接头在使用久了之后难免受空气的侵蚀，而在表面产生一层氧化物。
But there is one thing we should pay special attention to, before many people more processing sound more thin, to the last only clear and dry Alto, alto and thin enough rich bass voice, this is wrong. The correct sound should be water sweet soprano, alto plump plump, low volume feet and elasticity. Joint happiness, thread locking, the so-called joint is the joint signal input and output. The erosion of these joints will be subject to air after using for a long time, and produce a layer of oxide on the surface.
接头公插与母插上都有一层氧化物时，您花大钱买的讯号线还有用吗?要用什么东西来清洁接头呢?市面上有许多种小到具可以清除，您到音响店问一问就有了。 假若接头氧化得很厉害，您还可以到汽车材料行去买类似洁铝99的东西，这些具有摩擦性的清洁剂很厉害，会把接头表面磨掉薄薄一层，保证清洁溜溜。
The male plug and the female plug connector on a layer of oxide, signal lines, you spend a lot of money to buy is also useful to clean the joint? What? There are many small to can clear the market, you have to ask the audio shop. If the joint oxidation badly, you can also auto material for to buy things like clean aluminum 99, the cleaning agent with the friction is very fierce, will take joint surface wear off a thin layer, ensure clean yo.
不过要特别注意的是，千万不要拿这种清洁剂来擦济南音响面板或镀金旋钮，那会让它们变得没有镀金的光泽.
But special attention is, do not take this detergent to wipe Ji'nan audio panel or a gilded knob, that will make them become not gold luster.
