音响设备在使用中的禁忌
Taboos in use of sound equipment
我们经常在舞台上遇到很多关于音响的问题,比如说某天音箱突然点不着了,完全没有声音,又比如说音响声音变得混浊或者高音上不去了等。为什么会出现这样的状况呢,除了与使用寿命相关,日常如何使用也是一门学问。
We often have a lot of questions about the sound on the stage, for example, one day the sound box is suddenly missing, there is no sound at all, such as the sound of the sound becomes cloudy or the high pitched. Why is there such a situation, in addition to its life expectancy, how to use it everyday is also a learning.
下面为大家总结:
The following will be summed up as follows:
一、注意音箱的接线问题。在听音时要先检查接线是否正确,电位器位置是否过大。现在的音箱绝大部分是220伏电源设计,但也不排除有某些装进口回来的产品,这些音箱多是使用110伏的电源,由于电压不符,一个音箱就可能报废。
One, pay attention to the connection problem of the sound box. When listening, check whether the wiring is correct and whether the potentiometer position is too large. Now most of the sound box is 220 volt power supply design, but it does not exclude some imported products, these speakers are mostly the use of 110 volts power, because the voltage is not consistent, a sound box may be scrapped.
二、叠放器材。很多人会将扬声器、调谐器、数码模拟转换器等机器重叠放置,这会引起互相干扰,尤其是镭摄机与功放干扰严重,会使音色偏硬及产生压抑感。正确的做法是将器材放在由厂方设计的音响架上。
Two. Stack equipment. Many people will overlap the machine, such as loudspeaker, tuner, digital analog converter and so on. lvdai.75ix.com lvbang.75ix.com lvgan.75ix.com tongguan.75ix.comzhixiangb.75ix.com xishabeng.75ix.comThis can cause interference with each other, especially the interference of the radium camera and the power amplifier, which will make the tone hard and produce the sense of depression. The right thing to do is to put the equipment on the sound rack designed by the factory.
三、音箱清洁问题。在清洁音箱的时候还要注意清洗一下音箱线的接线端,因为音箱使用了一段时间以后音箱线的接线端或多或少都会被氧化,这层氧化膜会大大影响接触状态,从而令音质下降,用户应用清洁剂清洗接触点,以便保持最佳的连接状态。
Three. The problem of the sound box cleaning. When the sound box is cleaned, we should also pay attention to cleaning the connection end of the sound box line, because the sound box will be oxidized more or less after the use of the sound box for a period of time. This layer of oxide film will greatly affect the contact state, so that the sound quality is reduced, the user uses cleaning agent to clean the contact, in order to maintain the best connection. State.
四、接线处理不当。处理接线时不可把电源线与信号线扎在一起,因交流电会影响信号;信号线或喇叭线均不能打结,否则会影响音色。
Four. Improper handling of the wiring. When the wiring is handled, the power line and the signal line can not be tied together, because the alternating current will affect the signal; the signal line or the horn line can not be tied, otherwise it will affect the tone color.
五、忌话筒不要指向音箱。音箱的声音进入话筒,会形成声反馈,产生啸叫,后果严重者甚至会烧毁高音部分。其次,音箱也要远离强磁场,不要靠近易磁化的物品,如显示器和手机等,两个音箱放置的距离不能过近,以免出现噪音。
Five, avoid the microphone not to the sound box. When the sound of the speaker enters the microphone, it will generate acoustic feedback and generate howling, which will even burn up the high pitch part. Secondly, the sound box should be far away from the strong magnetic field, do not close to the easily magnetized items, such as display and mobile phone, etc., the distance between the two speakers can not be too close, so as to avoid noise.
