任何一套优良的
多媒体会议音响系统，都离不开音响工程人员的辛勤劳动，不论是音响的摆放位置的，还是调音。在工程施工中总是会遇到这样或者是那样的问题，针对这些问题，下面总结了几点，希望对大家有所帮助。
Any set of excellent multimedia conference sound system can not be separated from the hard work of sound engineers, whether it is the placement of sound or tuning. There are always problems in one way or another in the construction of the project. In view of these problems, the following is a summary of a few points, hoping to help you.
1、体系电平问题：在多媒体会议室音响工程中对于电平问题，要检查是不是功放的灵敏度操控开关翻开缺乏的情况造成，其次在检查一下体系中有没有做零电平调整。因为有时在调音台通道推一点点输出，就会产生很大的输出，在这种情况下就会直接的影响体系的动态和失真度。
1. System level problem: For the level problem in the multimedia conference room sound engineering, first check whether the sensitivity control switch of the power amplifier is not turned on, and then check whether the system has zero level adjustment. Because sometimes pushing a little output on the channel of the mixer will produce a large output, which will directly affect the dynamics and distortion of the system in this case.
2、线路衔接技术：是一种常见体系交流干扰声大，出现这种情况大多数都是由于线路衔接技术没有做到位引起的，对于体系中有平衡转换不平衡，或者是不平衡转换平衡的接法通常都要按规范衔接。
2. Line connection technology: It is a common system with high AC interference. Most of the reasons are that the line connection technology is not in place. The connection method with balanced or unbalanced conversion in the system should be connected according to the specifications.
3、信号分配方面的问题：如果在声场内有几组扬声器，用一台均衡器分配信号，就容易给分配信号的过程带来很多的麻烦，因为阻抗的匹配与否，点评分配的均衡与否等，在一台均衡器上面运用都很难好各个音箱的频率和声场。
3. The problem of signal distribution: if there are several groups of speakers in the sound field and a single equalizer is used to distribute the signal, it is easy to bring a lot of trouble to the process of signal distribution, because it is difficult to use the frequency and sound field of each speaker on a single equalizer because of the matching of impedance and the balance of comment distribution.
4、作用回路处置：对于这种情况的处理方法可以取推子的后置信号，就能有效的防止话筒啸叫，如果在回来有条件的情况下可以占用一路通道，从而方便调试。
4. Action loop disposal: for this case, the post-signal of the pusher can be taken to effectively prevent the microphone from whistling. If it is possible to return, one channel can be occupied, which is convenient for debugging.
5、多媒体会议室音响工程中的图示均衡器的频点调整问题：频点问题我们比较常见的有燕子型、山峰型、波涛型叁种频谱波型状，但是在实际的运用中声场并不需求波形，因为声场频率特性曲线一般情况下都是相对平整的，如果将其调整为声场频率特性曲线，就会引起适得其反的效果。
5. The problem of frequency adjustment of graphic equalizer in multimedia conference room sound engineering: We usually have three kinds of spectral wave shapes: swallow type, peak type and wave type. However, in practical application, the sound field does not need waveform, because the frequency characteristic curve of the sound field is generally relatively flat. If we adjust it to the frequency characteristic curve of the sound field, it will cause the opposite effect.
6、低声信号处置：不仅需要选择恰当的信号获取位置，也需要设置好功放的功率。避免出现烧坏等情况。
6. Low-sound signal processing: not only need to select the appropriate signal acquisition location, but also need to set the power of the power amplifier. Avoid burning.
7、压限器调整问题：常用的方法有存在的问题是，铺排底子过度不仅会引起反作用，还会引起音响发不出声音的情况出现。
7. Pressure limiter adjustment problem: The common method has the problem that the excessive laying of the substrate will not only cause reaction, but also cause the situation that the audio system cannot produce sound.
此外多媒体会议室音响工程中的调音台是体系的操控中心，如果出现调音台上的高中低贰蚕均衡做平等大幅度的晋升，或是衰减，对于这种问题需求可以从头调试体系，但是不要过火调整调音台的贰蚕。更多相关内容就来我们网站

In addition, the mixer in the sound engineering of multimedia conference room is the control center of the system. If the EQ balance of the high, middle and low EQ on the mixer is promoted or attenuated by an equal margin, the system can be adjusted from scratch, but the EQ of the mixer should not be adjusted too much.
