1、音响器材正常的工作温度应该为18℃～45℃。温度太低会降低某些设备(如电子管机)的灵敏度;太高则容易烧坏元器件，或使元器件提早老化。夏天要特别注意降温和保持空气流通。
1. The normal working temperature of audio equipment should be 18 ℃ ~ 45 ℃. Too low temperature will reduce the sensitivity of some equipment (such as electronic tube machine); If it is too high, it is easy to burn the components or make the components aging early. Pay special attention to cooling and maintaining air circulation in summer.
2、音响器材切忌阳光直射，也要避免靠近热源，如暖气。
2. Audio equipment should not be exposed to direct sunlight and should not be close to heat sources, such as heating.
3、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。
3. After the audio equipment is used up, all function keys shall be reset. If the function key is not reset for a long time, its pull button spring is in a stressed state for a long time, which is easy to cause dysfunction.
4、开关音响电源之前，把功放的音量电位器旋小，这是对功放和音箱的一项有效的保护手段。这时候功放的功率放大几乎为零，少在误操作时也不于对音箱造成危害，插拔线时要关机插拔。
4. Before switching the audio power supply, turn the volume potentiometer of the power amplifier to the minimum, which is the most effective protection means for the power amplifier and speaker. At this time, the power amplification of the power amplifier is almost zero, at least in case of misoperation, it will not cause harm to the speaker. It is best to shut down and plug the cable.
5、开机时由前开后，即先开颁顿机，再开前级和后级，开机时把功放的音量电位器旋小。关机时先关功放，让功放的放大功能彻底关闭，这时候您再关掉前端设备时，不管产生再大的冲击电流也不会殃及功放和音箱了。同样关机时要把功放的音量电位器旋小，关或放后再关前能与颁顿机。
5. When starting up, turn on the CD player from front to back, that is, turn on the CD player first, and then turn on the front and rear stages. When starting up, turn the volume potentiometer of the power amplifier to the minimum. Turn off the power amplifier first to completely turn off the amplification function of the power amplifier. When you turn off the front-end equipment at this time, no matter how much impulse current is generated, it will not affect the power amplifier and speaker. Similarly, when shutting down, turn the volume potentiometer of the power amplifier to the minimum. It can be connected with the CD player before turning off or after playing.
6、别乱插拨接线，基本上所有扬声器产物也不能在播放音乐或开启大音量时插拨声音接线，因为插拨会引发接点电流不稳，因而产生尖音及拍声，这些高频声音可能会破坏喇叭单元，更有可能「烧喇叭」。因此，用家应养成先切断电源才插拨接线的习惯，这样能使喇叭寿命更长久。
6. Don't plug and dial the wiring randomly. Basically, all speaker products can't plug and dial the sound wiring when playing music or turning on high volume, because plug and dial will cause unstable contact current, resulting in sharp sound and beat sound. These high-frequency sounds may damage the speaker unit and "burn the speaker". Therefore, users should form the habit of cutting off the power supply before inserting and dialing the wiring, which can make the service life of the horn longer.
7、机器要常用。常用反而能延长机器寿命，如一些带电机的部体(录音座、激光唱机、激光视盘机等)。如果长期不转动，部分机件还会变形。
7. The machine should be used frequently. It can prolong the service life of machines in common use, such as some parts with motors (recording stand, CD player, laser disc player, etc.). If it does not rotate for a long time, some parts will be deformed.
8、要定期通电。在长期不使用的情况下尤其在潮湿、高温季节，每天通电半小时。这样可利用机内元器件工作时产生的热量来驱除潮气，避免内部线圈、扬声器音圈、变压器等受潮霉断。
8. Power on regularly. When it is not used for a long time, especially in wet and high temperature seasons, it is best to power on for half an hour every day. In this way, the heat generated by the components in the machine can be used to drive away the moisture, so as to avoid the internal coil, speaker voice coil, transformer, etc. from moisture and mildew.
9、每隔一段时间要用干净潮湿的软棉布擦拭机器表面;不用时，应用防尘罩或盖布把机器盖上，防止灰尘入内。很多玩家都喜欢将喇叭的防尘网取掉，使音质更清晰，但在喇叭没有保护的情况下使用，很有可能会意外破坏单元位置，当中尤以中音喇叭为「高危一族」。假如用家希望得到高质的音乐享受，不妨将前置叁个喇叭的防尘网取掉，后面仍盖上防尘网，当用完后记紧盖回，便可减少意外的发生。
9. Wipe the machine surface with clean and wet soft cotton cloth at regular intervals; When not in use, cover the machine with dust cover or cloth to prevent dust from entering. Many players like to remove the dust net of the horn to make the sound quality clearer, but if the horn is used without protection, it is likely to accidentally damage the unit position, especially the Alto horn is a "high-risk group". If users want to enjoy high-quality music, they might as well remove the dust net of the front three speakers, and it's best to cover the dust net at the back. When they use it up, remember to cover it back, so as to reduce the occurrence of accidents.
10、从电子学的原理来说，任何电子设备在带电工作状态都不应该连接或断开其它设备，这一点我想不用太多说明朋友们也能理解，带电插拔有源设备是十分危险的，尤其是贬顿惭滨线，甚麦克风这样的无源设备也不提倡带电插拨。
10. From the principle of electronics, any electronic equipment should not be connected or disconnected from other equipment in the live working state. I don't think it's necessary to explain that friends can understand that it's very dangerous to plug and unplug active equipment, especially HDMI cable, and even passive equipment such as microphone.
需要提醒的是千万不要开着功放去接音箱线，因为音箱的接线柱距离一般都很近，音箱线又是两条紧紧地并行的，接线时往往会不小心将喇叭线短路，其后果将是迅速烧毁功放。尽管有的功放设有保护线路，但有的纯功放为了提高音质，减少不必要的音染，往往会省掉这部分保护措施。因此"关机再接线"这句话早已成了发烧友必须遵守的一条规则了。
It should be reminded that never connect the speaker line with the power amplifier on, because the wiring posts of the speaker are generally very close, and the speaker lines are closely parallel. When wiring, the speaker line is often accidentally short circuited, and the consequence will be to quickly burn the power amplifier. Although some power amplifiers have protection lines, some pure power amplifiers often omit this part of protection measures in order to improve sound quality and reduce unnecessary sound pollution. Therefore, the phrase "shut down and then connect" has long become a rule that enthusiasts must abide by.
11、有些讲究一些的发烧友在功放热机时不会扭大音量与放一些爆棚的音乐，道理是功放元件刚开机时处于冷状态，这时就让其大电流工作会缩短其寿命。因而有些发烧友在刚开机半小时内只放一些轻柔的音乐与用中等音量听音乐，待机器热身后再开大音量欣赏。
11. Some fans who pay attention to some will not turn up the volume and play some loud music when the power amplifier is hot. The reason is that the power amplifier element is in a cold state when it is just turned on. At this time, making it work with high current will shorten its service life. Therefore, some enthusiasts only play some soft music and listen to music at medium volume within half an hour after the machine is turned on, and then turn it on at high volume after the machine warms up.
