說到贛州舞臺燈光大家都(dou)是不陌生(sheng)的(de)(de)(de)，平常在(zai)我們(men)的(de)(de)(de)日(ri)常生(sheng)活中就能經常看(kan)到，只是對于它的(de)(de)(de)維護和注(zhu)意事項我們(men)了解的(de)(de)(de)沒有那么的(de)(de)(de)清(qing)楚，今天(tian)就來和大家分享一下(xia)關于舞(wu)臺燈光要注(zhu)意的(de)(de)(de)點。

1、 開場前半小時，打開所有設備，進(jin)行低(di)溫(wen)預熱(re)，同時檢測(ce)所有設備及(ji)線(xian)路。低(di)溫(wen)狀態是指燈光(guang)微亮即可；

2、 開機預(yu)熱十五分鐘(zhong)后(hou)將所(suo)有設備歸零，讓設備散熱，散熱時間不低(di)于十五分鐘(zhong)；

3、 散(san)熱后(hou)，即可(ke)正(zheng)式進入音樂(le)演出階段；

4、 演出結(jie)束(shu)、客(ke)人離場后，燈光師(shi)應(ying)關閉所有所有設備(bei)(bei)，并讓(rang)設備(bei)(bei)散熱(re)十五(wu)至(zhi)二十分(fen)鐘(zhong)，然(ran)后將設備(bei)(bei)進行(xing)封存或(huo)遮罩(zhao)，燈光師(shi)方可離場。

舞(wu)(wu)臺(tai)燈光音(yin)響(xiang)(xiang)功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)匹配：從原則上(shang)來講，音(yin)箱(xiang)(xiang)額(e)(e)定(ding)(ding)(ding)功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)與(yu)(yu)功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)放(fang)額(e)(e)定(ding)(ding)(ding)功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)不一致(zhi)時，舞(wu)(wu)臺(tai)燈光音(yin)響(xiang)(xiang)對(dui)于功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)放(fang)來說(shuo)(shuo)，它的(de)(de)(de)功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)大小(xiao)只與(yu)(yu)音(yin)箱(xiang)(xiang)阻抗(kang)有關，而(er)與(yu)(yu)音(yin)箱(xiang)(xiang)額(e)(e)定(ding)(ding)(ding)功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)無關。無論音(yin)箱(xiang)(xiang)功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)與(yu)(yu)功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)放(fang)功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)是否相同(tong)，對(dui)功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)放(fang)工作無影響(xiang)(xiang)，只是對(dui)音(yin)箱(xiang)(xiang)本(ben)身安(an)全有關。如果(guo)音(yin)箱(xiang)(xiang)阻抗(kang)符合(he)匹配要求，舞(wu)(wu)臺(tai)燈光音(yin)響(xiang)(xiang)而(er)承受功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)比功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)放(fang)功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)小(xiao)，則推(tui)動(dong)功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)充足(zu)(zu)，聽(ting)起來很舒服。這(zhe)就是常說(shuo)(shuo)的(de)(de)(de)功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)放(fang)儲(chu)備功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)要大，才能充分(fen)地(di)表(biao)現出音(yin)樂全部(bu)內涵(han)，尤其是音(yin)樂中的(de)(de)(de)低頻(pin)部(bu)分(fen)，表(biao)現更為生動(dong)、有力(li)。這(zhe)是一種(zhong)較好的(de)(de)(de)匹配。如果(guo)音(yin)箱(xiang)(xiang)的(de)(de)(de)額(e)(e)定(ding)(ding)(ding)阻抗(kang)大于功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)放(fang)的(de)(de)(de)額(e)(e)定(ding)(ding)(ding)功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)，雖然二(er)者都能安(an)全的(de)(de)(de)工作，但這(zhe)時功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)放(fang)大器推(tui)動(dong)功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)顯得(de)不夠，舞(wu)(wu)臺(tai)燈光音(yin)響(xiang)(xiang)會覺(jue)得(de)響(xiang)(xiang)度(du)不足(zu)(zu)，往(wang)往(wang)出現已經(jing)開到(dao)飽(bao)和狀(zhuang)態，失(shi)真加(jia)劇，仍感到(dao)力(li)不從心。
