style="font-size:16px;"></span> </h1> <p> <p> <span style="font-size:16px;">1.音箱與功率放大器配置不合理</span> </p> <p> <span style="font-size:16px;">功率放大器的輸出功率太大，造成高音單元的損壞，其實(shí)不然。在專業(yè)場合下，揚(yáng)聲器一般可以承受3倍于額定功率的大信號(hào)沖擊，瞬時(shí)可承受5倍于額定功率的峰值沖擊而不會(huì)有問題的。因而，不是因意外強(qiáng)沖擊或話筒長時(shí)間嘯叫，而由功率放大器功率大而燒高音單元的情況是極少出現(xiàn)的。</span> </p> <p> <p> <span style="font-size:16px;">2.分頻器使用不當(dāng)</span> </p> <p> <span style="font-size:16px;">輸入端分頻點(diǎn)使用不當(dāng)，或揚(yáng)聲器工作頻率范圍不合理也是導(dǎo)致高音單元損壞的一個(gè)原因。在使用分頻器時(shí)，應(yīng)嚴(yán)格按廠家提供的揚(yáng)聲器工作頻率范圍來合理的選擇分頻點(diǎn)。高音揚(yáng)聲器的分頻點(diǎn)如果選擇偏低，承受功率負(fù)擔(dān)過重，就很容易燒毀高音單元，中音號(hào)筒也是如此。</span> </p> <p> <span style="font-size:16px;"> <p> 3、均衡器調(diào)試不當(dāng) </p> <p> 均衡器的調(diào)整也是至關(guān)重要的。頻率均衡器是為了補(bǔ)償室內(nèi)聲場的各種缺陷和揚(yáng)聲器的各頻率不均勻而設(shè)置的，應(yīng)該用實(shí)際頻譜分析儀或用其它的儀器進(jìn)行調(diào)試。調(diào)試后的傳輸頻率特性應(yīng)在一定范圍內(nèi)是比較平坦的。許多不具備音響知識(shí)的調(diào)音員隨意的進(jìn)行調(diào)試，甚至有相當(dāng)多的人，把均衡器的高頻和低頻部分提得過高，形成“V”字形。如果這些

</p> <p> <span style="font-size:16px;"> ②調(diào)試前一定要對(duì)系統(tǒng)、設(shè)備的設(shè)定情況進(jìn)行的檢查。因?yàn)榘惭b和單機(jī)檢查過程和系統(tǒng)調(diào)試的側(cè)重點(diǎn)畢竟不同，設(shè)備的設(shè)定情況往往是隨意的，在進(jìn)行調(diào)試前可能某些重要的設(shè)定鈕已經(jīng)和實(shí)際要求完全不同了，所以檢查是有必要的，比較好對(duì)各舞臺(tái)音響設(shè)備的設(shè)定情況作好記錄。</span>
