山东公共广播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给您解惑。
The loudspeakers in Shandong public address sound system often burn or break. Most people intuitively think that it is unbearable to turn on the loudspeakers too loudly, so they break the loudspeakers. In fact, there are many possible situations, such as the following situations and reasons.
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，30奥的小功率后级可能烧掉低阻抗大喇叭的。
1. Opening the horn too loudly will damage the horn. Another situation is that the power of the amplifier is not enough to turn it on hard, and the output is abnormal cutting signals, which will also damage the horn. It is recommended that users who prefer loud volume should buy high-power amplifiers. The 30W low-power rear stage may burn out the low impedance loudspeakers.
2、扩大机如果有直流输出，那一定会烧掉低音喇叭，甚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. If the amplifier has a DC output, it will definitely burn out the bass speakers, even a few tweeters. The reason is that there is no capacitor on the crossover path of the bass (or other sound path) speaker to isolate DC. Once DC is output, it is like passing DC electricity into the speaker and burning the crossover coil together. Therefore, when purchasing an amplifier, be sure to use an ammeter to measure whether there is DC output at the output terminals of the front stage and the rear stage. If there is DC output at the front stage, it is also possible to transmit DC to the horn through the amplifier output at the rear stage.
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，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，那也许烧掉您的喇叭够让您买好几部20惭贬锄的示波器了。
3. If you install it yourself, you must know the high frequency oscillation. If you install it yourself now, you should pay more attention to the high frequency oscillation, so that you can use the oscilloscope to check whether there is oscillation or DC output at the front and rear stages. If you do not find this situation, you may burn your horn to buy several 20MHz oscilloscopes.
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，上述的情况是喇叭常发生的原因，提供你作为日常保养的参考。
The rear stage of the vacuum tube with an output transformer (or for broadcasting) will not have DC output (it would be scary if there is one), but the vacuum tube machine has become popular again. Pay special attention to the fact that the vacuum tube machine is prone to high-frequency oscillation or interference. The above situation is the cause of frequent occurrence of the horn, which provides you with a reference for daily maintenance.
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。
Equipment should be re matched. Yin and Yang should be reconciled. I have always stressed that the importance of equipment matching is far greater than the quality of individual equipment. If the cheap equipment is properly matched, its performance will certainly be better than the poorly matched high price equipment. The principle of equipment matching is to find the balance point, just like a seesaw, to find the balance point in the middle.
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。更多相关音响设备系统的信息就来我们网站

For this reason, if the equipment is masculine, we will match it with a feminine one to make its personality sound smooth. If we think the timbre is too bright, we will find warm equipment to match; If the speed is too slow, we will match it with a fast one.
