音响工程是一个比较大的工程,在安装中要注意,而且音响工程安装中有很多的问题,音响工程中常见问题的解决方法有哪些呢?下面山东音响厂家为您解答。
Sound engineering is a relatively large project. Attention should be paid to during installation. There are many problems in the installation of sound engineering. What are the solutions to common problems in sound engineering? Next, Shandong audio manufacturer will answer for you.
1.信号分配的问题: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品牌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。
1. Signal distribution: When there are several groups of speakers in the sound field, one equalizer is often used to distribute the signal to multiple power amplifiers to drive 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.
2.均衡器的频点调整问题:其实理想的声场频率特性曲线应该是相对平坦的,如果人为凭想象调整声场频率特性曲线,可想而知其结果是事与愿违。
2. Frequency adjustment of the equalizer: In fact, the ideal sound field frequency characteristic curve should be relatively flat. If you adjust the sound field frequency characteristic curve by imagination, you can imagine that the result is contrary to your expectations.
3.压限器调整问题:常见是做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。
3. Adjustment problem of pressure limiter: the common problem is that the equipment does not work at all and the excessive action is counterproductive. 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.
4.系统电平问题:首先是功放灵敏度控制开关打开不足,其次系统没有做零电平调整。有时调音台通道推一点点输出已很大,这种情况会影响系统的动态和失真度。
4. System level problem: First, the sensitivity control switch of the power amplifier is not open enough, and then the system does not make zero level adjustment. Sometimes the output of the mixer channel is very large after pushing a little bit, which will affect the dynamics and distortion of the system.

5.低音信号处理:假如不做电子分频用全频信号直接给功放推动音箱虽然音箱有声音也不至于烧坏单元,但就其低单元发全频声音可想而知;但如果从系统中不恰当位置取得信号也会给现场控制带来不必要的麻烦。
5. Bass signal processing: If we don't do electronic frequency division, we can use full frequency signal to directly push the power amplifier. Although there is sound in the speaker, it will not burn the unit, but we can imagine that its low unit will emit full frequency sound; But if the signal is obtained from an inappropriate position in the system, it will also bring unnecessary trouble to the field control.
6.效果回路处理: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。
6. Effect loop processing: the post signal of the pusher should be taken to avoid the microphone howling caused by uncontrolled effect, and the return can occupy a channel conditionally, which is more convenient for debugging.
7.线路连接工艺: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一定要按标准连接。另外不要用劣质接插件。
7. Line connection process: common system AC interference is caused by poor line connection process, and the system with balanced to unbalanced and unbalanced to balanced connection must be connected according to the standard. In addition, do not use inferior connectors.
8.控制问题:调音台是系统的控制中心,有时调音台上的高中低EQ均衡做同等大幅度的提升或衰减则说明系统并未调好,需要重新调试系统,不要过分调整调音台的EQ。
8. Control problem: The mixer is the control center of the system. Sometimes, if the high, medium and low EQ balance on the mixer is raised or attenuated by the same margin, it means that the system is not well adjusted, and the system needs to be re debugged. Don't over adjust the EQ of the mixer.
此外要注意,音响器材用完后,各功能键要复位。如果功能键长期不复位,其牵拉钮簧长时期处于受力状态,就容易造成功能失常,所以相关额使用注意事项要了解到,您可以来我们网站https://www.wenguangzhineng.com咨询!
In addition, it should be noted that the function keys should be reset after the audio equipment is used up. If the function key is not reset for a long time, its pull button spring is under stress for a long time, which is likely to cause functional disorder.
