家庭影院音響不時發(fā)出嘶嘶的聲音，讓人無法忍受，其實出現(xiàn)這種問題，大部分不是音響本身的問題，而是用戶在音響的使用和保養(yǎng)中出現(xiàn)的失誤造成的，因此，
山東音響廠家要和大家分享的是如何正確使用和保養(yǎng)家庭影院音響的方法！
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、不要熱插拔線
1. Do not hot plug the cable
功放類千萬不能熱插拔信號線，尤其是HDMI線，雖然理論上HDMI線支持熱插拔，但實際中因為熱插拔燒壞功放輸出模塊的實例非常多，我們的售后服務人員手中就經(jīng)常碰過到類似產(chǎn)品燒HDMI的情況。
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.
因為，信號線在設計發(fā)送接收芯片時，采用的抗靜電保護電路一般都只能耐5-8千伏靜電電壓，但是實際生活中，如果環(huán)境干燥，同時又有產(chǎn)生靜電電壓的條件，有可能產(chǎn)生上萬伏的靜電電壓是常見的。
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.
在設計考究的源端和顯示端，一般都會犧牲一些電容余量而配置ESD保護電路。但是有的機器為了節(jié)省成本而沒有ESD保護電路，就可能在帶靜電HDMI線插入時燒毀芯片。
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、開關(guān)機前把音箱音量開到小
2. Turn down the volume of the loudspeaker before turning on/off the machine
功放芯片怕大(瞬間)電流直接沖擊，因此音箱開聲時好把音量開到小然后再開機，開機后可以正常調(diào)大音量。關(guān)機時也同樣先調(diào)小音量再關(guān)電源。
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
音箱大部分是木制結(jié)構(gòu)，木皮飾面，長期陽光直射，會使木紋起泡，嚴重的音箱箱體變形產(chǎn)生裂縫。所以，盡量不要把音箱放在窗戶或者陽臺邊。如果實在沒有辦法，也應該給音箱蓋上遮陽的罩子，聽時再取下。
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、發(fā)熱量大的后級不要音箱放的過近
4. Don't put the speaker too close to the rear stage with high heat
導致功放后級發(fā)熱量大的原因是音箱的輸入阻抗小于功放的輸出阻抗，建議可以在功放里加個風扇散熱，同時后級不要和音箱放的過近，功放好不要開到大聲，這樣不但聲音不好聽還有燒喇叭跟功放的危險。
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.
如果家庭音響系統(tǒng)使用和保養(yǎng)的方法恰當，就能夠保證您的音響器材處于佳狀態(tài)，同時還能增加其保值效果，反之，勢必會造成你視聽體驗上的不良感受！所以相關(guān)的使用維護方法要上心，您可以來我們網(wǎng)站
