表演舞台是音响使用量比较大的场合之一，但是如果
山东舞台音响出了问题会直接导致演出无法顺利进行。因此，我们须要知道舞台音响可能会遇到一些什么样的问题，下面来看看吧。
The performance stage is one of the occasions with a large amount of sound usage, but if there is a problem with Shandong stage sound, the performance will not go smoothly. Therefore, we need to know what problems stage acoustics may encounter. Let's take a look.
1线路要按标准连接
1 The line shall be connected according to the standard
常见系统交流干扰声大就是线路连接工艺没有做好造成的，还有系统中有平衡转不平衡及不平衡转平衡接法的务要按标准连接，另外不要用劣质接插件。
Common systems with high AC interference are caused by poor line connection process. In addition, if there are balanced to unbalanced and unbalanced to balanced connections in the system, make sure to connect according to the standard. In addition, do not use inferior connectors.
2调整压限器问题
2. Adjustment of pressure limiter
常见摆设根本不起作用和作用过度起反作用。前者可以将就用，后者则会带来严重影响系统的动态，表现为声音发不出来，明显表现是伴奏声越强人声就自然减弱使演唱者无所适从。
Common furnishings do not work at all and are counterproductive if they function excessively. The former can be put to use, while the latter will bring about a serious impact on the dynamics of the system, which is manifested in the inability to produce sound. It is obvious that the stronger the accompaniment sound, the weaker the voice will naturally weaken, leaving the singer at a loss.
3信号分配的问题
3 Signal distribution problems
在声场内有几组扬声器的情况下，常使用一台均衡器将信号分配给多台功放推动音箱。但同时也可能是不同公司型号的功放和音箱混在一起使用，这样分配信号带来很多问题，阻抗是否匹配，电平分配是否均衡，音箱所获得功率是否正常，以及用一台均衡很难调整好声场和音箱的频率特性。
When there are several groups of speakers in the sound field, an equalizer is often used to distribute the signal to multiple power amplifiers to push the speakers. But at the same time, it may also be that power amplifiers and speakers of different brands and models are used together, which causes many problems in signal distribution, such as whether the impedance matches, whether the level distribution is balanced, whether the power obtained by the speakers is normal, and it is difficult to adjust the frequency characteristics of the sound field and speakers with one equalizer.
4效果回路处理
4 Effect loop treatment
应该取推子的后置信号，避免效果不受控引起话筒啸叫，返回有条件占用一路通道，这样调试更方便。
The rear signal of the pusher should be taken to avoid the microphone howling due to uncontrolled effect, and the return can occupy a channel conditionally, which is more convenient for debugging.
5处理低音信号
5 Process bass signal
一是不做电子分频用全频信号直接给功放推动音箱，这样有声音也不于烧坏单元，但低单元发全频声音可想而知。如从系统中不恰当位置取得信号也会给现场控制带来不要的麻烦。二是不知从系统何处提取低音信号做处理。
First, instead of electronic frequency division, the full frequency signal is used to directly push the speaker to the power amplifier, so that the sound will not burn the unit, but it is conceivable that the full frequency sound is generated by the low unit. If the signal is obtained from an inappropriate position in the system, it will also bring unnecessary trouble to the field control. Second, I don't know where to extract bass signal from the system for processing.
