1、在公共廣播音響應用中，音響設備的正常工作溫度應為18℃~45℃。如果溫度過低，會降低一些機器（如管機）的靈活性；如果過高，容易燒壞元件，或導致元件過早老化。夏季要特別注意降溫，保持空氣流通。
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、音響設備不宜受陽光直射，也應避免接近熱源，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、音響設備用完后，功能鍵應復位。如果功能鍵長時間不復位，其拉鈕彈簧長期受力，容易引起誤動作。
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、在開啟和關閉音響電源之前，將功放的音量電位調到低，這是對功放和音箱有效的維護措施。此時副功放的功率放大幾乎為零，少在誤操作的情況下，不會對音箱造成傷害。
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、開機時從前到后開機，即先開CD機，再開前后級，開機時將功放的音量電位器調到小。關機時，先關閉功放，使功放的放大功能完全關閉。此時，關閉前端設備，無論浪涌電流有多大，功放和音箱都不會受到影響。
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、在公共廣播音響應用中，機器應該是常用的。常用的可以延長機器的壽命，比如一些帶電機的零件（錄音座、CD機、鐳射碟機等）。如果長時間不旋轉，一些零件會變形。
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、定期開機。在長期不使用的情況下，尤其是在潮濕高溫的季節，天開機半小時。這樣就可以利用機器內部件產生的熱量驅走濕氣，防止內部線圈、揚聲器音圈、變壓器等受潮發霉。
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、每隔一段時間用干凈濕潤的軟棉布擦拭機器外部；不使用時，用防塵罩或罩蓋蓋住機器，防止灰塵進入。
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、
山東公共廣播音響廠家認為，從電子學原理上看，任何電子設備在帶電工作時都不應連接或斷開其他設備。有源設備的插拔風險很大，即使是麥克風等無源設備也不建議帶電插拔。
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開功放接喇叭線，因為喇叭端子之間的距離通常很近，而且喇叭線是兩條緊密平行的，接線時經常會不小心把喇叭線短路，其結果將是放大器的快速燒壞。
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.
雖然有些功放有維修線，但有些HI-FI純功放為了提高音質，減少不必要的音染，往往會省略這部分維修措施。因此，“關機重線”這句話，一直以來都是發燒友必須遵守的規則。
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.
