音響設備的音質(zhì)功能肯定比其他音響的好，音響設備在使用的時(shí)候需要注意哪些事項呢？
The sound quality function of professional audio equipment is definitely better than that of other audio equipment. What should we pay attention to when using professional audio equipment?
1、如果音響設備長(cháng)時(shí)間工作在較大的輸入功率的狀態(tài)下，音圈可能由于溫度達到一百度以上而導致音箱燒毀。因此需要有一個(gè)能保證揚聲器長(cháng)時(shí)間正常工作的輸入電功率，即額定輸入功率，這個(gè)數據在設備的資料里都會(huì )給出，重要的是在使用中要嚴格執行，在擴聲效果不如人意的情況下應考慮改變配置，而不是簡(jiǎn)單地加大功率。
1. If the professional audio equipment works in the state of large input power for a long time, the voice coil may burn down due to the temperature reaching more than 100 ℃. Therefore, it is necessary to have an input power that can ensure the normal operation of the loudspeaker for a long time, that is, the rated input power. This data will be given in the data of the equipment. It is important to strictly implement it in use. When the sound reinforcement effect is not satisfactory, we should first consider changing the configuration rather than simply increasing the power.
2、音響設備如果使用不適當很容易引起嘯叫，為了減小散射聲，提高清晰度，要盡量把音箱的作用區指向受眾的座位方向。
2. If the professional audio equipment is not used properly, it is easy to cause howling. In order to reduce the scattered sound and improve the clarity, we should try to point the action area of the speaker to the seat direction of the audience.
3、工作中經(jīng)常同時(shí)使用多個(gè)音箱，在連接它們時(shí)一定要注意性問(wèn)題，所有的揚聲器應當一致，如果連接后的揚聲器不同，則聲音輸出將相互干涉，聽(tīng)起來(lái)感覺(jué)低音不足，明顯的不調和音。
3. We often use multiple speakers at the same time in our work. When we connect them, we must pay attention to sex. All the speakers should be the same. If the connected speakers are different, the sound output will interfere with each other. It sounds like the bass is insufficient, and there is obvious disharmony.
4、放大器與音響設備之間的功率要匹配。重放聲音的綜合音質(zhì)不僅取決于音箱的特性，也取決于放大器的輸出及負載特性。如果聲音不理想，不要只想到是音箱出了問(wèn)題，而應當考慮與它相連的放大系統是否存在問(wèn)題。
4. The power between amplifier and professional audio equipment should match. The comprehensive sound quality of the playback sound depends not only on the characteristics of the speaker, but also on the output and load characteristics of the amplifier. If the sound is not ideal, don't just think that there is a problem with the speaker, but first consider whether there is a problem with the amplifier system connected to it.
音響設備使用安 全要點(diǎn)與注意事項
Safety points and precautions for the use of audio equipment
音響燈光的各個(gè)應用領(lǐng)域，安 全問(wèn)題一直以來(lái)是大家為關(guān)注的焦點(diǎn)，雖然每一次安 全事故，都有不同的發(fā)生原因。但有一點(diǎn)是共同的，那就是生產(chǎn)方都忽視了現場(chǎng)的安 全，或者說(shuō)在安 全防范上做得不到位。
In various application fields of sound and lighting, safety has always been the focus of attention, although every safety accident has different causes. But there is one thing in common, that is, the producers ignore the safety of the site, or do not do a good job in safety prevention.
對于音響設備操作人員來(lái)說(shuō)，尤其要注意在使用設備的過(guò)程中的操作細節！不少用電器都是在火線(xiàn)的位置上有保險絲，接反會(huì )造成保險絲斷后用電器依然帶電的情況。
For audio equipment operators, pay special attention to the operation details in the process of using the equipment! Many electrical appliances have fuses in the position of the live wire. If they are connected reversely, the electrical appliances will still be charged after the fuse is broken.
較好能用雙保險絲和雙刀開(kāi)關(guān)，可同時(shí)切斷火線(xiàn)與零線(xiàn)。排式插座是直接連著(zhù)用電設備的，在接上穩壓器等保護裝置確定無(wú)異常才可在關(guān)閉的狀態(tài)下將各個(gè)設備接上。需要注意排插與電源的接觸良好。開(kāi)機前少要確認功率放大器開(kāi)關(guān)是否關(guān)著(zhù)且音量位置小。
It can use double fuse and double pole switch to cut off live line and zero line at the same time. The row type socket is directly connected to the electrical equipment. Only when the voltage regulator and other protection devices are connected, and it is confirmed that there is no abnormality, can each equipment be connected in the closed state. Attention should be paid to the good contact between the plug and the power supply. At least make sure that the power amplifier switch is off and the volume position is low before starting.
