一、效果器電源對音色的影響大嗎

效果器(qi)電(dian)源(yuan)對音色有(you)影(ying)響，一個差勁(jing)的(de)(de)電(dian)源(yuan)會(hui)(hui)為(wei)你的(de)(de)演(yan)奏帶來(lai)噪(zao)聲，更重要(yao)的(de)(de)是會(hui)(hui)帶來(lai)其他更嚴重的(de)(de)問題(ti)，比(bi)如漏(lou)電(dian)，比(bi)如效果器(qi)重啟。沒有(you)什么比(bi)正在臺上忘情(qing)演(yan)出而這時聲音嘎然而止更郁悶(men)的(de)(de)事情(qing)了。如果使用的(de)(de)電(dian)壓(ya)不穩定，那(nei)么就(jiu)會(hui)(hui)發(fa)生重啟的(de)(de)情(qing)況。

二、效果器電源如何選擇

1、首先先了解一下最基本的電源規格：

直流用DC表示；交(jiao)流用AC表示。提示：在選擇電源的時候，必須確認你的效果器是直流供電還是交(jiao)流（大部(bu)分(fen)是直流），千萬不能搞混！

電(dian)壓：用(yong)伏特（V）來表示，常見的(de)效果器電(dian)源是9V的(de)，也有12V、15V、24V等(deng)各種。

提示：在選擇電(dian)(dian)源的(de)時(shi)候，必(bi)須保證電(dian)(dian)源的(de)輸(shu)出電(dian)(dian)壓和效果(guo)器要求(qiu)的(de)電(dian)(dian)壓是一致的(de)！

電(dian)流：用(yong)毫安(an)（mA）來表示，通(tong)常效果器電(dian)流都是幾十到幾百毫安(an)。

提示：電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)的(de)(de)輸(shu)出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)不(bu)(bu)需要和(he)效果(guo)(guo)(guo)器(qi)(qi)要求的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)完(wan)(wan)全(quan)一致(zhi)，只(zhi)要保(bao)證(zheng)大(da)于效果(guo)(guo)(guo)器(qi)(qi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)即(ji)可。比如，效果(guo)(guo)(guo)器(qi)(qi)上(shang)寫(xie)的(de)(de)是(shi)(shi)200mA，那么(me)你選擇400mA甚至更大(da)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)也(ye)是(shi)(shi)可以用(yong)(yong)的(de)(de)，因(yin)為電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)上(shang)寫(xie)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)是(shi)(shi)指最大(da)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)參數(shu)，而不(bu)(bu)是(shi)(shi)不(bu)(bu)管你接什(shen)么(me)效果(guo)(guo)(guo)器(qi)(qi)，它永遠都輸(shu)出那么(me)大(da)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)，這一點通常是(shi)(shi)很(hen)容易混淆的(de)(de)，很(hen)多(duo)人反映(ying)說我找不(bu)(bu)到完(wan)(wan)全(quan)一致(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)大(da)小(xiao)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)，就是(shi)(shi)他們認為電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)大(da)小(xiao)必須是(shi)(shi)完(wan)(wan)全(quan)一致(zhi)的(de)(de)，這是(shi)(shi)錯誤(wu)的(de)(de)，實際(ji)上(shang)不(bu)(bu)需要完(wan)(wan)全(quan)一致(zhi)，只(zhi)要大(da)于就可以。但不(bu)(bu)能小(xiao)于要求電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)，如果(guo)(guo)(guo)你的(de)(de)效果(guo)(guo)(guo)器(qi)(qi)要求的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)是(shi)(shi)800mA，那么(me)400mA的(de)(de)這款電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)就不(bu)(bu)能夠被使用(yong)(yong)了。如果(guo)(guo)(guo)你是(shi)(shi)用(yong)(yong)一塊電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)同時帶好(hao)幾(ji)個效果(guo)(guo)(guo)器(qi)(qi)的(de)(de)話(hua)，則要保(bao)證(zheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)的(de)(de)最大(da)輸(shu)出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)大(da)于等于所有效果(guo)(guo)(guo)器(qi)(qi)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)總和(he)。

極(ji)性(xing)：也(ye)就是正負(fu)級(ji)，通常(chang)單塊(kuai)效(xiao)果器(qi)的(de)極(ji)性(xing)都(dou)是外正內負(fu)的(de)，也(ye)有(you)相(xiang)反的(de)，而常(chang)用的(de)民用設備(bei)的(de)電(dian)源通常(chang)是外負(fu)內正的(de)。

提示(shi)：只(zhi)有直流電源才存在極(ji)性的標(biao)記，交流電源是(shi)沒(mei)有的。極(ji)性也是(shi)絕對要確認符合的參數之一，不能相反。

2、效果器的電源規格

然后來(lai)檢查(cha)自(zi)己效果器上所要求的(de)電(dian)源規(gui)格(ge)是(shi)什么，通常你(ni)會在效果器電(dian)源插口(kou)附近或者背面的(de)規(gui)格(ge)說明(ming)里找到(dao)電(dian)源規(gui)格(ge)要求，也可以參看說明(ming)書(shu)來(lai)確認。

比如(ru)說效(xiao)果器上(shang)邊緣寫著9V、DC、外正內(nei)負，就(jiu)是使用外正內(nei)伏極性的(de)(de)9伏直流電(dian)的(de)(de)意(yi)思，這(zhe)種規格(ge)(ge)是最常(chang)見的(de)(de)單(dan)塊效(xiao)果器的(de)(de)電(dian)源規格(ge)(ge)，通(tong)(tong)常(chang)這(zhe)種規格(ge)(ge)的(de)(de)效(xiao)果器都是支持使用電(dian)池(chi)供(gong)電(dian)的(de)(de)。這(zhe)里沒有(you)寫明(ming)電(dian)流大(da)小，所(suo)以就(jiu)需要查看(kan)說明(ming)書來確認，不過一般可以使用電(dian)池(chi)的(de)(de)效(xiao)果器的(de)(de)電(dian)流都不會很大(da)，通(tong)(tong)常(chang)幾百毫安都足夠，而大(da)部分電(dian)源都至少(shao)是200mA以上(shang)的(de)(de)，通(tong)(tong)常(chang)都可以用。如(ru)果電(dian)流要求比較大(da)的(de)(de)話，通(tong)(tong)常(chang)效(xiao)果器上(shang)都會有(you)標明(ming)。

3、然后來看電源上面標明的規格

一(yi)款SPOT效果器(qi)(qi)專用(yong)電(dian)源(yuan)(yuan)，輸入的規格(ge)是(shi)100-240V，也就(jiu)是(shi)說是(shi)從100V到240V電(dian)壓都(dou)可使用(yong)，后面(mian)的50/60HZ以(yi)及(ji)0.35A這個(ge)可以(yi)不看。輸出(chu)規格(ge)是(shi)9V DC，直(zhi)流，輸出(chu)電(dian)流最大可以(yi)達到1700毫安，因此它可以(yi)為(wei)多塊效果器(qi)(qi)提供電(dian)源(yuan)(yuan)，極性是(shi)外(wai)正(zheng)內(nei)負。
