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、音響器材切忌陽(yáng)光直射，也要避免靠近熱源，如暖氣。

2. Audio equipment should not be exposed to direct sunlight and should not be close to heat sources, such as heating.

3、音響器材用完后，各功能鍵要復(fù)位。如果功能鍵長(zhǎng)期不復(fù)位，其牽拉鈕簧長(zhǎng)時(shí)期處于受力狀態(tài)，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、開(kāi)關(guān)音響電源之前，把功放的音量電位器旋小，這是對(duì)功放和音箱的一項(xiàng)有效的保護(hù)手段。這時(shí)候功放的功率放大幾乎為零，少在誤操作時(shí)也不于對(duì)音箱造成危害，插拔線時(shí)要關(guān)機(jī)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、開(kāi)機(jī)時(shí)由前開(kāi)后，即先開(kāi)CD機(jī)，再開(kāi)前級(jí)和后級(jí)，開(kāi)機(jī)時(shí)把功放的音量電位器旋小。關(guān)機(jī)時(shí)先關(guān)功放，讓功放的放大功能徹底關(guān)閉，這時(shí)候您再關(guān)掉前端設(shè)備時(shí)，不管產(chǎn)生再大的沖擊電流也不會(huì)殃及功放和音箱了。同樣關(guān)機(jī)時(shí)要把功放的音量電位器旋小，關(guān)或放后再關(guān)前能與CD機(jī)。

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、別亂插撥接線，基本上所有揚(yáng)聲器產(chǎn)品也不能在播放音樂(lè)或開(kāi)啟大音量時(shí)插撥聲音接線，因?yàn)椴鍝軙?huì)引發(fā)接點(diǎn)電流不穩(wěn)，因而產(chǎn)生尖音及拍聲，這些高頻聲音可能會(huì)破壞喇叭單元，更有可能「燒喇叭」。因此，用家應(yīng)養(yǎng)成先切斷電源才插撥接線的習(xí)慣，這樣能使喇叭壽命更長(zhǎng)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、機(jī)器要常用。常用反而能延長(zhǎng)機(jī)器壽命，如一些帶電機(jī)的部體(錄音座、激光唱機(jī)、激光視盤(pán)機(jī)等)。如果長(zhǎng)期不轉(zhuǎn)動(dòng)，部分機(jī)件還會(huì)變形。

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、要定期通電。在長(zhǎng)期不使用的情況下尤其在潮濕、高溫季節(jié)，每天通電半小時(shí)。這樣可利用機(jī)內(nèi)元器件工作時(shí)產(chǎn)生的熱量來(lái)驅(qū)除潮氣，避免內(nèi)部線圈、揚(yáng)聲器音圈、變壓器等受潮霉斷。

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、每隔一段時(shí)間要用干凈潮濕的軟棉布擦拭機(jī)器表面;不用時(shí)，應(yīng)用防塵罩或蓋布把機(jī)器蓋上，防止灰塵入內(nèi)。很多玩家都喜歡將喇叭的防塵網(wǎng)取掉，使音質(zhì)更清晰，但在喇叭沒(méi)有保護(hù)的情況下使用，很有可能會(huì)意外破壞單元位置，當(dāng)中尤以中音喇叭為「高危一族」。假如用家希望得到高質(zhì)的音樂(lè)享受，不妨將前置三個(gè)喇叭的防塵網(wǎng)取掉，后面仍蓋上防塵網(wǎng)，當(dāng)用完后記緊蓋回，便可減少意外的發(fā)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、從電子學(xué)的原理來(lái)說(shuō)，任何電子設(shè)備在帶電工作狀態(tài)都不應(yīng)該連接或斷開(kāi)其它設(shè)備，這一點(diǎn)我想不用太多說(shuō)明朋友們也能理解，帶電插拔有源設(shè)備是十分危險(xiǎn)的，尤其是HDMI線，甚麥克風(fēng)這樣的無(wú)源設(shè)備也不提倡帶電插撥。

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.

需要提醒的是千萬(wàn)不要開(kāi)著功放去接音箱線，因?yàn)橐粝涞慕泳€柱距離一般都很近，音箱線又是兩條緊緊地并行的，接線時(shí)往往會(huì)不小心將喇叭線短路，其后果將是迅速燒毀功放。盡管有的功放設(shè)有保護(hù)線路，但有的純功放為了提高音質(zhì)，減少不必要的音染，往往會(huì)省掉這部分保護(hù)措施。因此"關(guān)機(jī)再接線"這句話早已成了發(fā)燒友必須遵守的一條規(guī)則了。

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、有些講究一些的發(fā)燒友在功放熱機(jī)時(shí)不會(huì)扭大音量與放一些爆棚的音樂(lè)，道理是功放元件剛開(kāi)機(jī)時(shí)處于冷狀態(tài)，這時(shí)就讓其大電流工作會(huì)縮短其壽命。因而有些發(fā)燒友在剛開(kāi)機(jī)半小時(shí)內(nèi)只放一些輕柔的音樂(lè)與用中等音量聽(tīng)音樂(lè)，待機(jī)器熱身后再開(kāi)大音量欣賞。

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.
