家庭影院音响不时发出嘶嘶的声音，让人无法忍受，其实出现这种问题，大部分不是音响本身的问题，而是用户在音响的使用和保养中出现的失误造成的，因此，
山东音响厂家要和大家分享的是如何正确使用和保养家庭影院音响的方法！
It's unbearable that the home theater stereo makes a hissing sound from time to time. In fact, most of the problems are not caused by the stereo itself, but by the user's mistakes in the use and maintenance of the stereo. Therefore, Shandong professional audio manufacturers want to share with you how to use and maintain the home theater stereo correctly!
1、不要热插拔线
1. Do not hot plug the cable
功放类千万不能热插拔信号线，尤其是贬顿惭滨线，虽然理论上贬顿惭滨线支持热插拔，但实际中因为热插拔烧坏功放输出模块的实例非常多，我们的售后服务人员手中就经常碰过到类似产物烧贬顿惭滨的情况。
The power amplifier class must not hot plug the signal line, especially the HDMI line. Although the HDMI line theoretically supports hot plug, in practice, because there are many instances of hot plug burning the power amplifier output module, our after-sales service personnel often encounter similar products burning HDMI.
因为，信号线在设计发送接收芯片时，采用的抗静电保护电路一般都只能耐5-8千伏静电电压，但是实际生活中，如果环境干燥，同时又有产生静电电压的条件，有可能产生上万伏的静电电压是常见的。
Because, when designing the sending and receiving chip, the anti-static protection circuit adopted by the signal line can only withstand 5-8 kV static voltage. However, in real life, if the environment is dry and there are conditions for generating static voltage, it is common to generate tens of thousands of volts of static voltage.
在设计考究的源端和显示端，一般都会牺牲一些电容余量而配置贰厂顿保护电路。但是有的机器为了节省成本而没有贰厂顿保护电路，就可能在带静电贬顿惭滨线插入时烧毁芯片。
In the well-designed source and display terminals, ESD protection circuits are generally configured at the expense of some capacitance margin. However, some machines do not have ESD protection circuit in order to save costs, which may burn the chip when the static HDMI cable is inserted.
2、开关机前把音箱音量开到小
2. Turn down the volume of the loudspeaker before turning on/off the machine
功放芯片怕大(瞬间)电流直接冲击，因此音箱开声时好把音量开到小然后再开机，开机后可以正常调大音量。关机时也同样先调小音量再关电源。
The power amplifier chip is afraid of direct impact of large (instantaneous) current, so it is better to turn down the volume when the speaker is turned on, and then turn it on again. After turning it on, you can normally turn up the volume. Turn down the volume before turning off the power.
3、避免日光直射
3. Avoid direct sunlight
音箱大部分是木制结构，木皮饰面，长期阳光直射，会使木纹起泡，严重的音箱箱体变形产生裂缝。所以，尽量不要把音箱放在窗户或者阳台边。如果实在没有办法，也应该给音箱盖上遮阳的罩子，听时再取下。
Most of the speakers are made of wood, with wood veneer. Long term direct sunlight will make the wood grain blister, causing serious deformation and cracks. Therefore, try not to put the speaker near the window or balcony. If there is no way out, you should also cover the speaker with a sunshade and take it off when listening.
4、发热量大的后级不要音箱放的过近
4. Don't put the speaker too close to the rear stage with high heat
导致功放后级发热量大的原因是音箱的输入阻抗小于功放的输出阻抗，建议可以在功放里加个风扇散热，同时后级不要和音箱放的过近，功放好不要开到大声，这样不但声音不好听还有烧喇叭跟功放的危险。
The reason for the high heat generation of the rear stage of the power amplifier is that the input impedance of the speaker is smaller than the output impedance of the power amplifier. It is recommended that a fan be added to the power amplifier to dissipate heat. At the same time, the rear stage should not be too close to the speaker, and the power amplifier should not be turned on loud when it is good. In this way, not only the sound is bad, but also the risk of burning the horn and the power amplifier.
