說到贛州舞臺燈光大(da)家(jia)都是不陌生的(de)(de)(de)，平常在我們(men)的(de)(de)(de)日常生活(huo)中就能經常看(kan)到，只是對于它的(de)(de)(de)維護和(he)(he)注意事項我們(men)了解的(de)(de)(de)沒有那么(me)的(de)(de)(de)清(qing)楚，今天就來和(he)(he)大(da)家(jia)分(fen)享一下(xia)關(guan)于舞臺燈光要注意的(de)(de)(de)點。

1、 開場前(qian)半小時，打開所有(you)設備，進行(xing)低溫預熱(re)，同時檢測所有(you)設備及線路。低溫狀態(tai)是指燈光微亮即可；

2、 開(kai)機預(yu)熱十五分(fen)鐘后將所有設(she)備歸(gui)零，讓設(she)備散(san)熱，散(san)熱時(shi)間(jian)不低(di)于十五分(fen)鐘；

3、 散熱后(hou)，即可(ke)正式(shi)進入音樂演出階段；

4、 演出(chu)結束(shu)、客人離(li)場后，燈光師(shi)應關閉(bi)所有所有設備(bei)，并讓(rang)設備(bei)散熱十五(wu)至二十分鐘，然后將設備(bei)進(jin)行封存(cun)或遮罩，燈光師(shi)方可離(li)場。

舞(wu)(wu)臺(tai)(tai)燈(deng)光(guang)(guang)音(yin)(yin)響功(gong)(gong)(gong)(gong)率(lv)(lv)匹(pi)配(pei)：從原則上來(lai)講(jiang)，音(yin)(yin)箱額定功(gong)(gong)(gong)(gong)率(lv)(lv)與(yu)(yu)功(gong)(gong)(gong)(gong)放(fang)(fang)額定功(gong)(gong)(gong)(gong)率(lv)(lv)不(bu)(bu)一(yi)致時，舞(wu)(wu)臺(tai)(tai)燈(deng)光(guang)(guang)音(yin)(yin)響對(dui)于(yu)(yu)功(gong)(gong)(gong)(gong)放(fang)(fang)來(lai)說，它的功(gong)(gong)(gong)(gong)率(lv)(lv)大(da)小只與(yu)(yu)音(yin)(yin)箱阻抗(kang)有關(guan)，而(er)與(yu)(yu)音(yin)(yin)箱額定功(gong)(gong)(gong)(gong)率(lv)(lv)無(wu)(wu)關(guan)。無(wu)(wu)論音(yin)(yin)箱功(gong)(gong)(gong)(gong)率(lv)(lv)與(yu)(yu)功(gong)(gong)(gong)(gong)放(fang)(fang)功(gong)(gong)(gong)(gong)率(lv)(lv)是否相同(tong)，對(dui)功(gong)(gong)(gong)(gong)放(fang)(fang)工作(zuo)無(wu)(wu)影響，只是對(dui)音(yin)(yin)箱本(ben)身安全(quan)(quan)有關(guan)。如果音(yin)(yin)箱阻抗(kang)符(fu)合匹(pi)配(pei)要(yao)(yao)求，舞(wu)(wu)臺(tai)(tai)燈(deng)光(guang)(guang)音(yin)(yin)響而(er)承(cheng)受功(gong)(gong)(gong)(gong)率(lv)(lv)比功(gong)(gong)(gong)(gong)放(fang)(fang)功(gong)(gong)(gong)(gong)率(lv)(lv)小，則推動(dong)功(gong)(gong)(gong)(gong)率(lv)(lv)充足，聽起(qi)來(lai)很(hen)舒服。這(zhe)(zhe)就(jiu)是常(chang)說的功(gong)(gong)(gong)(gong)放(fang)(fang)儲備功(gong)(gong)(gong)(gong)率(lv)(lv)要(yao)(yao)大(da)，才能(neng)充分地表現(xian)(xian)出(chu)音(yin)(yin)樂全(quan)(quan)部內涵，尤其是音(yin)(yin)樂中的低頻部分，表現(xian)(xian)更為生動(dong)、有力。這(zhe)(zhe)是一(yi)種較好的匹(pi)配(pei)。如果音(yin)(yin)箱的額定阻抗(kang)大(da)于(yu)(yu)功(gong)(gong)(gong)(gong)放(fang)(fang)的額定功(gong)(gong)(gong)(gong)率(lv)(lv)，雖然二者都能(neng)安全(quan)(quan)的工作(zuo)，但(dan)這(zhe)(zhe)時功(gong)(gong)(gong)(gong)率(lv)(lv)放(fang)(fang)大(da)器推動(dong)功(gong)(gong)(gong)(gong)率(lv)(lv)顯得(de)不(bu)(bu)夠，舞(wu)(wu)臺(tai)(tai)燈(deng)光(guang)(guang)音(yin)(yin)響會覺得(de)響度不(bu)(bu)足，往(wang)往(wang)出(chu)現(xian)(xian)已經(jing)開到(dao)飽和狀態，失真加(jia)劇(ju)，仍(reng)感到(dao)力不(bu)(bu)從心。
