說到贛州舞臺燈光大(da)家都是(shi)(shi)不陌生(sheng)的，平常在我們的日(ri)常生(sheng)活(huo)中就能經常看到，只是(shi)(shi)對于(yu)它的維(wei)護和(he)注意(yi)事(shi)項(xiang)我們了(le)解的沒有那么的清(qing)楚，今(jin)天就來和(he)大(da)家分享一(yi)下關于(yu)舞臺燈光要注意(yi)的點。

1、 開場前半(ban)小(xiao)時，打開所(suo)有(you)設(she)備，進行低溫(wen)(wen)預熱(re)，同時檢測所(suo)有(you)設(she)備及線路。低溫(wen)(wen)狀態是指(zhi)燈光微亮(liang)即可；

2、 開機預熱(re)十五分鐘后將(jiang)所有設備(bei)歸零，讓設備(bei)散熱(re)，散熱(re)時間(jian)不低于(yu)十五分鐘；

3、 散(san)熱(re)后，即(ji)可正式進入(ru)音樂演出階段；

4、 演出結(jie)束、客人離(li)場后(hou)，燈(deng)光(guang)師應(ying)關閉所有(you)所有(you)設備(bei)，并讓設備(bei)散熱十(shi)五至二十(shi)分鐘，然后(hou)將設備(bei)進行封存(cun)或遮罩，燈(deng)光(guang)師方可離(li)場。

舞臺燈(deng)光音(yin)響(xiang)功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)(lv)匹(pi)配(pei)(pei)：從(cong)原則上來(lai)(lai)講(jiang)，音(yin)箱(xiang)(xiang)額(e)定功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)(lv)與功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)放額(e)定功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)(lv)不(bu)一致(zhi)時(shi)，舞臺燈(deng)光音(yin)響(xiang)對于(yu)功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)放來(lai)(lai)說，它(ta)的功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)(lv)大(da)小只與音(yin)箱(xiang)(xiang)阻抗有(you)關，而與音(yin)箱(xiang)(xiang)額(e)定功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)(lv)無(wu)關。無(wu)論(lun)音(yin)箱(xiang)(xiang)功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)(lv)與功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)放功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)(lv)是(shi)否相同(tong)，對功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)放工(gong)作(zuo)無(wu)影響(xiang)，只是(shi)對音(yin)箱(xiang)(xiang)本(ben)身安全有(you)關。如果音(yin)箱(xiang)(xiang)阻抗符(fu)合匹(pi)配(pei)(pei)要求，舞臺燈(deng)光音(yin)響(xiang)而承受(shou)功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)(lv)比功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)放功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)(lv)小，則推(tui)動功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)(lv)充(chong)足(zu)，聽起來(lai)(lai)很(hen)舒服。這(zhe)(zhe)就是(shi)常說的功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)放儲備功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)(lv)要大(da)，才能充(chong)分地(di)表(biao)(biao)現(xian)出音(yin)樂全部(bu)內(nei)涵，尤其(qi)是(shi)音(yin)樂中的低頻部(bu)分，表(biao)(biao)現(xian)更(geng)為生動、有(you)力(li)。這(zhe)(zhe)是(shi)一種(zhong)較好(hao)的匹(pi)配(pei)(pei)。如果音(yin)箱(xiang)(xiang)的額(e)定阻抗大(da)于(yu)功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)放的額(e)定功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)(lv)，雖然二(er)者都能安全的工(gong)作(zuo)，但這(zhe)(zhe)時(shi)功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)(lv)放大(da)器推(tui)動功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)(lv)顯(xian)得不(bu)夠，舞臺燈(deng)光音(yin)響(xiang)會(hui)覺得響(xiang)度(du)不(bu)足(zu)，往往出現(xian)已經開到飽和狀態(tai)，失真加劇(ju)，仍感到力(li)不(bu)從(cong)心。
