很多人实际工作中可能都碰到这样的问题，在有乐队的演出时，乐手说返听不够大或者返听听不清，要求控制人员提高他的返听音量。有时候提高了返听的音量后，乐手仍然会提出要求。返听音量大了，话筒啸叫的可能性也大了，就会进入一个恶性循环，有时处理不好的时候，往往就容易引发乐手和音响控制人员的纠纷。
Many people may encounter such problems in their actual work. When there is a band performance, the musician says that the return is not big enough or can not hear clearly, and asks the controller to increase his return volume. Sometimes, after increasing the volume of return listening, the musician will still ask for it. When the volume of return listening is high, the possibility of microphone howling is also high, and it will enter a vicious circle. Sometimes when it is not handled well, it is easy to cause disputes between musicians and sound controllers.
其实返听系统本来是给演员服务的音响系统，用来让乐手监听自己的演奏或演唱效果，及时进行调整。所以监听系统是否能够真实表达乐手的演奏情况是非常重要的一个方面。
In fact, the back listening system was originally a sound system for actors, which was used to let musicians monitor their performance or singing effect and make adjustments in time. Therefore, whether the monitoring system can truly express the performance of musicians is a very important aspect.
大多数的情况下舞台返听系统是从调音台础鲍齿输出接一个均衡器然后到功放到音箱。很多人对舞台返听的处理往往比较片面，此时的均衡器往往只注重用于处理话筒啸叫，在这种用法之下，返听音箱发出的声音往往是有缺陷的，对乐器声音的还原性大大降低。
In most cases, the stage hearing back system is connected to an equalizer from the AUX output of the mixer, and then to the power amplifier to the speaker. Many people tend to deal with stage listening back one sidedly. At this time, the equalizer is often only used to deal with the roar of the microphone. Under this usage, the sound emitted by the listening back speaker is often defective, and the reducibility of the sound of the musical instrument is greatly reduced.
舞台上的人员听到的声音不是他想象的那种声音效果，就感觉听着不对，但他们往往不懂音响的还原性，所以以为是音量不够，所以要求提高音量。此时，你就是把音量提高了，乐手还会抱怨听不清，根源就是还原性不好，返听声音不够清晰。这就好比一个说话吐字不清的人，小声说话的时候你听不清他说什么，如果让他大声说话，你就更听不清了。
The sound heard by the people on the stage is not the kind of sound effect he imagined, so they feel that it doesn't sound right, but they often don't understand the reducibility of the sound, so they think the volume is not enough, so they ask to increase the volume. At this time, you just raise the volume, and the musicians will complain that they can't hear clearly. The root cause is that the reducibility is not good and the back listening sound is not clear enough. It's like a person who can't speak clearly. You can't hear what he says when he speaks quietly. If you let him speak loudly, you can't hear clearly.
所以要解决这个问题，是要提供一个还原性比较好的舞台返听系统，还原性好了，清晰度就会上去，不需要开多大的音量就可以让演职人员清晰听到自己的演奏效果了。
Therefore, to solve this problem, the first thing is to provide a stage listening back system with good reducibility. When the reducibility is good, the clarity will go up. It doesn't need to turn on much volume to let the performers clearly hear their performance effect.
要提高系统还原性，就要针对系统的扩声缺陷使用均衡器进行有针对性的补偿。等系统还原性高了，表达清晰了，也就不需要开得惊天动地，话筒啸叫的可能性也会大大降低的。
In order to improve the reducibility of the system, it is necessary to use the equalizer to compensate the sound reinforcement defects of the system. When the system has high reducibility and clear expression, there is no need to drive earth shaking, and the possibility of microphone howling will be greatly reduced.
