說到贛州舞臺燈光大(da)家都是不陌生的(de)(de)(de)(de)，平(ping)常(chang)在我們的(de)(de)(de)(de)日常(chang)生活中就能經(jing)常(chang)看(kan)到，只是對于它的(de)(de)(de)(de)維(wei)護(hu)和注(zhu)意(yi)事(shi)項(xiang)我們了解的(de)(de)(de)(de)沒有那么的(de)(de)(de)(de)清楚，今(jin)天就來和大(da)家分享一下關于舞臺燈光要注(zhu)意(yi)的(de)(de)(de)(de)點。

1、 開場前半小時，打(da)開所(suo)有(you)設備，進行低(di)溫預(yu)熱，同時檢測所(suo)有(you)設備及線路(lu)。低(di)溫狀態是指燈光微(wei)亮即可；

2、 開(kai)機預熱十五(wu)分(fen)(fen)鐘(zhong)后將所有設(she)備歸零，讓設(she)備散熱，散熱時間不(bu)低(di)于十五(wu)分(fen)(fen)鐘(zhong)；

3、 散熱(re)后，即可正式進入音(yin)樂演(yan)出(chu)階段；

4、 演出結束、客(ke)人離場后，燈光(guang)師(shi)應關閉(bi)所(suo)有所(suo)有設(she)備，并(bing)讓設(she)備散熱十五至二十分鐘(zhong)，然后將(jiang)設(she)備進行封(feng)存或遮(zhe)罩，燈光(guang)師(shi)方可離場。

舞(wu)臺燈光(guang)音(yin)(yin)(yin)(yin)響(xiang)(xiang)功(gong)(gong)(gong)(gong)率(lv)(lv)(lv)匹配(pei)(pei)：從(cong)原(yuan)則上來(lai)講，音(yin)(yin)(yin)(yin)箱(xiang)(xiang)額定(ding)(ding)功(gong)(gong)(gong)(gong)率(lv)(lv)(lv)與(yu)功(gong)(gong)(gong)(gong)放(fang)(fang)額定(ding)(ding)功(gong)(gong)(gong)(gong)率(lv)(lv)(lv)不(bu)(bu)(bu)一(yi)致時，舞(wu)臺燈光(guang)音(yin)(yin)(yin)(yin)響(xiang)(xiang)對于(yu)功(gong)(gong)(gong)(gong)放(fang)(fang)來(lai)說，它(ta)的(de)功(gong)(gong)(gong)(gong)率(lv)(lv)(lv)大(da)(da)(da)小只(zhi)與(yu)音(yin)(yin)(yin)(yin)箱(xiang)(xiang)阻抗(kang)有(you)關(guan)，而(er)與(yu)音(yin)(yin)(yin)(yin)箱(xiang)(xiang)額定(ding)(ding)功(gong)(gong)(gong)(gong)率(lv)(lv)(lv)無(wu)(wu)關(guan)。無(wu)(wu)論音(yin)(yin)(yin)(yin)箱(xiang)(xiang)功(gong)(gong)(gong)(gong)率(lv)(lv)(lv)與(yu)功(gong)(gong)(gong)(gong)放(fang)(fang)功(gong)(gong)(gong)(gong)率(lv)(lv)(lv)是(shi)否相同(tong)，對功(gong)(gong)(gong)(gong)放(fang)(fang)工作無(wu)(wu)影(ying)響(xiang)(xiang)，只(zhi)是(shi)對音(yin)(yin)(yin)(yin)箱(xiang)(xiang)本(ben)身(shen)安全有(you)關(guan)。如果音(yin)(yin)(yin)(yin)箱(xiang)(xiang)阻抗(kang)符合(he)匹配(pei)(pei)要求，舞(wu)臺燈光(guang)音(yin)(yin)(yin)(yin)響(xiang)(xiang)而(er)承受功(gong)(gong)(gong)(gong)率(lv)(lv)(lv)比(bi)功(gong)(gong)(gong)(gong)放(fang)(fang)功(gong)(gong)(gong)(gong)率(lv)(lv)(lv)小，則推動功(gong)(gong)(gong)(gong)率(lv)(lv)(lv)充(chong)足，聽起(qi)來(lai)很舒(shu)服。這(zhe)(zhe)就(jiu)是(shi)常說的(de)功(gong)(gong)(gong)(gong)放(fang)(fang)儲備功(gong)(gong)(gong)(gong)率(lv)(lv)(lv)要大(da)(da)(da)，才能充(chong)分(fen)地表現(xian)出音(yin)(yin)(yin)(yin)樂全部內涵(han)，尤其是(shi)音(yin)(yin)(yin)(yin)樂中(zhong)的(de)低頻部分(fen)，表現(xian)更為生動、有(you)力。這(zhe)(zhe)是(shi)一(yi)種較(jiao)好的(de)匹配(pei)(pei)。如果音(yin)(yin)(yin)(yin)箱(xiang)(xiang)的(de)額定(ding)(ding)阻抗(kang)大(da)(da)(da)于(yu)功(gong)(gong)(gong)(gong)放(fang)(fang)的(de)額定(ding)(ding)功(gong)(gong)(gong)(gong)率(lv)(lv)(lv)，雖然二者(zhe)都能安全的(de)工作，但這(zhe)(zhe)時功(gong)(gong)(gong)(gong)率(lv)(lv)(lv)放(fang)(fang)大(da)(da)(da)器推動功(gong)(gong)(gong)(gong)率(lv)(lv)(lv)顯得(de)不(bu)(bu)(bu)夠，舞(wu)臺燈光(guang)音(yin)(yin)(yin)(yin)響(xiang)(xiang)會覺得(de)響(xiang)(xiang)度(du)不(bu)(bu)(bu)足，往往出現(xian)已經開到飽(bao)和狀態(tai)，失真(zhen)加劇，仍感到力不(bu)(bu)(bu)從(cong)心。
