說到贛州舞臺燈光大家都(dou)是(shi)不陌(mo)生(sheng)(sheng)的，平(ping)常在我們的日常生(sheng)(sheng)活中就(jiu)能經常看到，只(zhi)是(shi)對于它(ta)的維護和注意事項我們了解的沒有那(nei)么的清楚，今天就(jiu)來和大家分享一下關(guan)于舞(wu)臺燈(deng)光要注意的點。

1、 開場前半(ban)小時，打開所有設(she)備(bei)，進行低(di)溫(wen)預熱(re)，同時檢(jian)測(ce)所有設(she)備(bei)及線路。低(di)溫(wen)狀態是指燈光(guang)微亮即可；

2、 開機(ji)預熱十五分鐘(zhong)后(hou)將所有設備歸零，讓設備散(san)熱，散(san)熱時間(jian)不低(di)于十五分鐘(zhong)；

3、 散熱后，即可正式進入(ru)音樂演(yan)出階段(duan)；

4、 演出結束、客人離場后(hou)，燈光師(shi)應關閉(bi)所有所有設備(bei)，并讓設備(bei)散(san)熱(re)十(shi)五至(zhi)二(er)十(shi)分鐘，然后(hou)將設備(bei)進(jin)行封存或遮罩，燈光師(shi)方可離場。

舞(wu)(wu)臺(tai)(tai)燈(deng)光(guang)音(yin)響(xiang)(xiang)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)匹配(pei)：從原(yuan)則上來講，音(yin)箱(xiang)(xiang)(xiang)額(e)定(ding)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)與(yu)功(gong)(gong)(gong)(gong)(gong)(gong)放(fang)額(e)定(ding)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)不(bu)(bu)(bu)一致(zhi)時(shi)，舞(wu)(wu)臺(tai)(tai)燈(deng)光(guang)音(yin)響(xiang)(xiang)對于功(gong)(gong)(gong)(gong)(gong)(gong)放(fang)來說，它的(de)(de)(de)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)大小只與(yu)音(yin)箱(xiang)(xiang)(xiang)阻抗有關，而(er)與(yu)音(yin)箱(xiang)(xiang)(xiang)額(e)定(ding)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)無(wu)關。無(wu)論音(yin)箱(xiang)(xiang)(xiang)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)與(yu)功(gong)(gong)(gong)(gong)(gong)(gong)放(fang)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)是(shi)否(fou)相同，對功(gong)(gong)(gong)(gong)(gong)(gong)放(fang)工(gong)作無(wu)影響(xiang)(xiang)，只是(shi)對音(yin)箱(xiang)(xiang)(xiang)本身(shen)安全有關。如果(guo)音(yin)箱(xiang)(xiang)(xiang)阻抗符合匹配(pei)要求(qiu)，舞(wu)(wu)臺(tai)(tai)燈(deng)光(guang)音(yin)響(xiang)(xiang)而(er)承(cheng)受功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)比功(gong)(gong)(gong)(gong)(gong)(gong)放(fang)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)小，則推(tui)動功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)充(chong)足(zu)，聽起來很(hen)舒服。這(zhe)就是(shi)常說的(de)(de)(de)功(gong)(gong)(gong)(gong)(gong)(gong)放(fang)儲(chu)備(bei)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)要大，才(cai)能充(chong)分(fen)地表現出音(yin)樂全部內涵，尤其是(shi)音(yin)樂中的(de)(de)(de)低頻部分(fen)，表現更為生動、有力。這(zhe)是(shi)一種較好的(de)(de)(de)匹配(pei)。如果(guo)音(yin)箱(xiang)(xiang)(xiang)的(de)(de)(de)額(e)定(ding)阻抗大于功(gong)(gong)(gong)(gong)(gong)(gong)放(fang)的(de)(de)(de)額(e)定(ding)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)，雖然(ran)二者(zhe)都(dou)能安全的(de)(de)(de)工(gong)作，但這(zhe)時(shi)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)放(fang)大器推(tui)動功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)顯得不(bu)(bu)(bu)夠，舞(wu)(wu)臺(tai)(tai)燈(deng)光(guang)音(yin)響(xiang)(xiang)會(hui)覺(jue)得響(xiang)(xiang)度不(bu)(bu)(bu)足(zu)，往往出現已經開(kai)到(dao)飽和狀態(tai)，失真加劇，仍感到(dao)力不(bu)(bu)(bu)從心。
