音響設(shè)備的音質(zhì)功能肯定比其他音響的好，音響設(shè)備在使用的時(shí)候需要注意哪些事項(xiàng)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(shè)備長(zhǎng)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(dá)到一百度以上而導(dǎo)致音箱燒毀。因此需要有一個(gè)能保證揚(yáng)聲器長(zhǎng)時(shí)間正常工作的輸入電功率，即額定輸入功率，這個(gè)數(shù)據(jù)在設(shè)備的資料里都會(huì)給出，重要的是在使用中要嚴(yán)格執(zhí)行，在擴(kuò)聲效果不如人意的情況下應(yīng)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(shè)備如果使用不適當(dāng)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(qū)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(yáng)聲器應(yīng)當(dāng)一致，如果連接后的揚(yáng)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(diào)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(shè)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(fù)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(yīng)當(dāng)考慮與它相連的放大系統(tǒng)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(shè)備使用安 全要點(diǎn)與注意事項(xiàng)
Safety points and precautions for the use of audio equipment
音響燈光的各個(gè)應(yīng)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(xiàn)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(duì)于音響設(shè)備操作人員來(lái)說(shuō)，尤其要注意在使用設(shè)備的過(guò)程中的操作細(xì)節(jié)！不少用電器都是在火線的位置上有保險(xiǎn)絲，接反會(huì)造成保險(xiǎn)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(xiǎn)絲和雙刀開(kāi)關(guān)，可同時(shí)切斷火線與零線。排式插座是直接連著用電設(shè)備的，在接上穩(wěn)壓器等保護(hù)裝置確定無(wú)異常才可在關(guān)閉的狀態(tài)下將各個(gè)設(shè)備接上。需要注意排插與電源的接觸良好。開(kāi)機(jī)前少要確認(rèn)功率放大器開(kāi)關(guān)是否關(guān)著且音量位置小。
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.
