1、在公共广播音响应用中，音响设备的正常工作温度应为18℃词45℃。如果温度过低，会降低一些机器（如管机）的灵活性；如果过高，容易烧坏元件，或导致元件过早老化。夏季要特别注意降温，保持空气流通。
1. In public address audio applications, the normal operating temperature of audio equipment shall be 18 ℃ ~45 ℃. If the temperature is too low, the flexibility of some machines (such as pipe machine) will be reduced; If it is too high, it is easy to burn out the components or cause premature aging of the components. In summer, pay special attention to cooling and maintain air circulation.
2、音响设备不宜受阳光直射，也应避免接近热源，如取暖器等。
2. Sound equipment should not be exposed to direct sunlight, and should not be close to heat sources, such as heaters.
3、音响设备用完后，功能键应复位。如果功能键长时间不复位，其拉钮弹簧长期受力，容易引起误动作。
3. After the audio equipment is used up, the function key should be reset. If the function key does not reset for a long time, the pull button spring will be stressed for a long time, which is easy to cause malfunction.
4、在开启和关闭音响电源之前，将功放的音量电位调到低，这是对功放和音箱有效的维护措施。此时副功放的功率放大几乎为零，少在误操作的情况下，不会对音箱造成伤害。
4. Before turning on and off the audio power supply, adjust the volume potential of the power amplifier to low, which is an effective maintenance measure for the power amplifier and speaker. At this time, the power amplification of the sub power amplifier is almost zero. At least in the case of misoperation, it will not cause damage to the speaker.
5、开机时从前到后开机，即先开颁顿机，再开前后级，开机时将功放的音量电位器调到小。关机时，先关闭功放，使功放的放大功能完全关闭。此时，关闭前端设备，无论浪涌电流有多大，功放和音箱都不会受到影响。
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 down the volume potentiometer of the power amplifier. When shutting down, turn off the power amplifier first to completely turn off the amplification function of the power amplifier. At this time, turn off the front-end equipment. No matter how large the surge current is, the power amplifier and speaker will not be affected.
6、在公共广播音响应用中，机器应该是常用的。常用的可以延长机器的寿命，比如一些带电机的零件（录音座、颁顿机、镭射碟机等）。如果长时间不旋转，一些零件会变形。
6. In public address audio applications, the machine should be commonly used. Common ones can prolong the service life of the machine, such as some parts with motors (recording stand, CD player, laser disc player, etc.). If you do not rotate for a long time, some parts will deform.
7、定期开机。在长期不使用的情况下，尤其是在潮湿高温的季节，天开机半小时。这样就可以利用机器内部件产生的热量驱走湿气，防止内部线圈、扬声器音圈、变压器等受潮发霉。
7. Power on regularly. When it is not used for a long time, especially in humid and hot seasons, it can be turned on for half an hour every day. In this way, the heat generated by the internal parts of the machine can be used to drive away the moisture and prevent the internal coils, speaker voice coils, transformers, etc. from becoming damp and moldy.
8、每隔一段时间用干净湿润的软棉布擦拭机器外部；不使用时，用防尘罩或罩盖盖住机器，防止灰尘进入。
8. Wipe the outside of the machine with clean and wet soft cotton cloth at regular intervals; When not in use, cover the machine with dust cover or cover to prevent dust from entering.
9、厂家认为，从电子学原理上看，任何电子设备在带电工作时都不应连接或断开其他设备。有源设备的插拔风险很大，即使是麦克风等无源设备也不建议带电插拔。
9. Shandong public broadcasting audio manufacturers believe that, from the perspective of electronic principle, any electronic equipment should not be connected or disconnected from other equipment when working with electricity. There is a great risk of plugging in and out of active equipment, and hot plugging is not recommended even for passive equipment such as microphones.
需要提醒的是不要打开功放接喇叭线，因为喇叭端子之间的距离通常很近，而且喇叭线是两条紧密平行的，接线时经常会不小心把喇叭线短路，其结果将是放大器的快速烧坏。
It should be noted that do not open the power amplifier to connect the horn cable, because the distance between the horn terminals is usually very close, and the two horn cables are closely parallel. During wiring, the horn cable is often accidentally short circuited, and the result will be rapid burnout of the amplifier.
虽然有些功放有维修线，但有些贬滨-贵滨纯功放为了提高音质，减少不必要的音染，往往会省略这部分维修措施。因此，&濒诲辩耻辞;关机重线&谤诲辩耻辞;这句话，一直以来都是发烧友必须遵守的规则。
Although some power amplifiers have maintenance lines, some hi-fi pure power amplifiers often omit these maintenance measures in order to improve sound quality and reduce unnecessary sound pollution. Therefore, the phrase "shut down and rewire" has always been a rule that enthusiasts must abide by.
公共广播音响想用长久就要做好有关事项的内容就是以上了，要想更好更长久的使用音响，就要平常中多检查定期保养维护。更多信息的获取就来关注我们网站吧！
If you want to use the public address sound system for a long time, you should do a good job in the above matters. If you want to use the sound system for a better and longer time, you should check and maintain it regularly. For more information, please follow our website www.wenguangzhining Com!
