1、在公共廣播音響應(yīng)用中，音響設(shè)備的正常工作溫度應(yīng)為18℃~45℃。如果溫度過(guò)低，會(huì)降低一些機(jī)器（如管機(jī)）的靈活性；如果過(guò)高，容易燒壞元件，或?qū)е略^(guò)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(shè)備不宜受陽(yáng)光直射，也應(yīng)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(shè)備用完后，功能鍵應(yīng)復(fù)位。如果功能鍵長(zhǎng)時(shí)間不復(fù)位，其拉鈕彈簧長(zhǎng)期受力，容易引起誤動(dòng)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(kāi)啟和關(guān)閉音響電源之前，將功放的音量電位調(diào)到低，這是對(duì)功放和音箱有效的維護(hù)措施。此時(shí)副功放的功率放大幾乎為零，少在誤操作的情況下，不會(huì)對(duì)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(kāi)機(jī)時(shí)從前到后開(kāi)機(jī)，即先開(kāi)CD機(jī)，再開(kāi)前后級(jí)，開(kāi)機(jī)時(shí)將功放的音量電位器調(diào)到小。關(guān)機(jī)時(shí)，先關(guān)閉功放，使功放的放大功能完全關(guān)閉。此時(shí)，關(guān)閉前端設(shè)備，無(wú)論浪涌電流有多大，功放和音箱都不會(huì)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(yīng)用中，機(jī)器應(yīng)該是常用的。常用的可以延長(zhǎng)機(jī)器的壽命，比如一些帶電機(jī)的零件（錄音座、CD機(jī)、鐳射碟機(jī)等）。如果長(zhǎng)時(shí)間不旋轉(zhuǎn)，一些零件會(huì)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(kāi)機(jī)。在長(zhǎng)期不使用的情況下，尤其是在潮濕高溫的季節(jié)，天開(kāi)機(jī)半小時(shí)。這樣就可以利用機(jī)器內(nèi)部件產(chǎn)生的熱量驅(qū)走濕氣，防止內(nèi)部線圈、揚(yáng)聲器音圈、變壓器等受潮發(fā)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(shí)間用干凈濕潤(rùn)的軟棉布擦拭機(jī)器外部；不使用時(shí)，用防塵罩或罩蓋蓋住機(jī)器，防止灰塵進(jìn)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(rèn)為，從電子學(xué)原理上看，任何電子設(shè)備在帶電工作時(shí)都不應(yīng)連接或斷開(kāi)其他設(shè)備。有源設(shè)備的插拔風(fēng)險(xiǎn)很大，即使是麥克風(fēng)等無(wú)源設(shè)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(kāi)功放接喇叭線，因?yàn)槔榷俗又g的距離通常很近，而且喇叭線是兩條緊密平行的，接線時(shí)經(jīng)常會(huì)不小心把喇叭線短路，其結(jié)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(zhì)，減少不必要的音染，往往會(huì)省略這部分維修措施。因此，“關(guān)機(jī)重線”這句話，一直以來(lái)都是發(fā)燒友必須遵守的規(guī)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.
公共廣播音響想用長(zhǎng)久就要做好有關(guān)事項(xiàng)的內(nèi)容就是以上了，要想更好更長(zhǎng)久的使用音響，就要平常中多檢查定期保養(yǎng)維護(hù)。更多信息的獲取就來(lái)關(guān)注我們網(wǎng)站
