一、效果器電源對音色的影響大嗎

效(xiao)果器電(dian)源(yuan)對(dui)音色(se)有(you)(you)影響，一個差勁的(de)(de)電(dian)源(yuan)會為(wei)你(ni)的(de)(de)演奏帶來噪聲，更重(zhong)要(yao)的(de)(de)是會帶來其他更嚴重(zhong)的(de)(de)問(wen)題，比如漏電(dian)，比如效(xiao)果器重(zhong)啟。沒有(you)(you)什么比正在臺上忘情演出而(er)這(zhe)時聲音嘎然(ran)而(er)止更郁悶的(de)(de)事(shi)情了。如果使用的(de)(de)電(dian)壓不穩定，那么就會發生(sheng)重(zhong)啟的(de)(de)情況(kuang)。

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(liu)(liu)用DC表(biao)示(shi)；交(jiao)流(liu)(liu)用AC表(biao)示(shi)。提示(shi)：在選擇電源的時候，必須確認(ren)你的效果(guo)器是直流(liu)(liu)供(gong)電還是交(jiao)流(liu)(liu)（大部分是直流(liu)(liu)），千(qian)萬不能搞混！

電壓：用伏特(te)（V）來表示，常(chang)見(jian)的效果(guo)器電源是9V的，也有12V、15V、24V等各種(zhong)。

提示(shi)：在選擇電(dian)(dian)源(yuan)的時候，必須保證電(dian)(dian)源(yuan)的輸出(chu)電(dian)(dian)壓和(he)效(xiao)果器要求的電(dian)(dian)壓是一致的！

電(dian)流：用毫(hao)(hao)安（mA）來表示(shi)，通常(chang)效果器電(dian)流都是幾十到幾百毫(hao)(hao)安。

提示(shi)：電(dian)(dian)(dian)(dian)(dian)(dian)源的(de)(de)(de)(de)輸(shu)(shu)出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)不(bu)(bu)需要和效(xiao)(xiao)(xiao)果(guo)(guo)(guo)(guo)器(qi)(qi)要求的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)完全一致(zhi)，只要保(bao)證(zheng)大(da)于(yu)效(xiao)(xiao)(xiao)果(guo)(guo)(guo)(guo)器(qi)(qi)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)即可(ke)(ke)。比如，效(xiao)(xiao)(xiao)果(guo)(guo)(guo)(guo)器(qi)(qi)上寫(xie)的(de)(de)(de)(de)是(shi)(shi)(shi)200mA，那么你(ni)(ni)選(xuan)擇400mA甚至(zhi)更大(da)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)源也是(shi)(shi)(shi)可(ke)(ke)以(yi)用的(de)(de)(de)(de)，因為(wei)電(dian)(dian)(dian)(dian)(dian)(dian)源上寫(xie)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)是(shi)(shi)(shi)指最(zui)大(da)供電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)的(de)(de)(de)(de)參(can)數，而不(bu)(bu)是(shi)(shi)(shi)不(bu)(bu)管你(ni)(ni)接什么效(xiao)(xiao)(xiao)果(guo)(guo)(guo)(guo)器(qi)(qi)，它永遠都(dou)輸(shu)(shu)出(chu)那么大(da)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)，這(zhe)(zhe)一點通常是(shi)(shi)(shi)很(hen)容易混(hun)淆的(de)(de)(de)(de)，很(hen)多人反映說我找不(bu)(bu)到完全一致(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)大(da)小的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)源，就是(shi)(shi)(shi)他們(men)認為(wei)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)大(da)小必(bi)須是(shi)(shi)(shi)完全一致(zhi)的(de)(de)(de)(de)，這(zhe)(zhe)是(shi)(shi)(shi)錯誤的(de)(de)(de)(de)，實際(ji)上不(bu)(bu)需要完全一致(zhi)，只要大(da)于(yu)就可(ke)(ke)以(yi)。但不(bu)(bu)能(neng)小于(yu)要求電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)，如果(guo)(guo)(guo)(guo)你(ni)(ni)的(de)(de)(de)(de)效(xiao)(xiao)(xiao)果(guo)(guo)(guo)(guo)器(qi)(qi)要求的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)是(shi)(shi)(shi)800mA，那么400mA的(de)(de)(de)(de)這(zhe)(zhe)款電(dian)(dian)(dian)(dian)(dian)(dian)源就不(bu)(bu)能(neng)夠被使用了。如果(guo)(guo)(guo)(guo)你(ni)(ni)是(shi)(shi)(shi)用一塊電(dian)(dian)(dian)(dian)(dian)(dian)源同(tong)時(shi)帶好幾(ji)個(ge)效(xiao)(xiao)(xiao)果(guo)(guo)(guo)(guo)器(qi)(qi)的(de)(de)(de)(de)話(hua)，則要保(bao)證(zheng)電(dian)(dian)(dian)(dian)(dian)(dian)源的(de)(de)(de)(de)最(zui)大(da)輸(shu)(shu)出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)大(da)于(yu)等于(yu)所有效(xiao)(xiao)(xiao)果(guo)(guo)(guo)(guo)器(qi)(qi)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)總和。

極(ji)性：也(ye)就(jiu)是(shi)正(zheng)負(fu)級，通(tong)常(chang)單塊效果器的(de)(de)(de)極(ji)性都是(shi)外(wai)(wai)正(zheng)內負(fu)的(de)(de)(de)，也(ye)有相反(fan)的(de)(de)(de)，而(er)常(chang)用(yong)的(de)(de)(de)民用(yong)設備的(de)(de)(de)電(dian)源通(tong)常(chang)是(shi)外(wai)(wai)負(fu)內正(zheng)的(de)(de)(de)。

提示：只有直流電(dian)源(yuan)才存在(zai)極性的標記，交流電(dian)源(yuan)是沒有的。極性也是絕對要(yao)確(que)認符(fu)合的參數之一，不(bu)能(neng)相反。

2、效果器的電源規格

然后來檢(jian)查自己效果器(qi)上所要求的電源規格是什么，通常你會在(zai)效果器(qi)電源插口附(fu)近或者背(bei)面的規格說(shuo)明(ming)里找到電源規格要求，也可以(yi)參(can)看說(shuo)明(ming)書來確認。

比(bi)如(ru)說效(xiao)果(guo)(guo)器(qi)上(shang)邊緣寫著(zhu)9V、DC、外正內(nei)負，就是使用(yong)外正內(nei)伏極性的(de)(de)(de)9伏直流電(dian)(dian)(dian)(dian)的(de)(de)(de)意思(si)，這種(zhong)規格是最常(chang)(chang)見的(de)(de)(de)單塊(kuai)效(xiao)果(guo)(guo)器(qi)的(de)(de)(de)電(dian)(dian)(dian)(dian)源(yuan)規格，通(tong)常(chang)(chang)這種(zhong)規格的(de)(de)(de)效(xiao)果(guo)(guo)器(qi)都(dou)(dou)是支持使用(yong)電(dian)(dian)(dian)(dian)池(chi)(chi)供電(dian)(dian)(dian)(dian)的(de)(de)(de)。這里沒有寫明(ming)電(dian)(dian)(dian)(dian)流大(da)(da)小(xiao)，所(suo)以就需要(yao)查看說明(ming)書來確認，不(bu)過(guo)一般可(ke)以使用(yong)電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)效(xiao)果(guo)(guo)器(qi)的(de)(de)(de)電(dian)(dian)(dian)(dian)流都(dou)(dou)不(bu)會很大(da)(da)，通(tong)常(chang)(chang)幾百毫安都(dou)(dou)足夠(gou)，而大(da)(da)部分電(dian)(dian)(dian)(dian)源(yuan)都(dou)(dou)至少是200mA以上(shang)的(de)(de)(de)，通(tong)常(chang)(chang)都(dou)(dou)可(ke)以用(yong)。如(ru)果(guo)(guo)電(dian)(dian)(dian)(dian)流要(yao)求(qiu)比(bi)較大(da)(da)的(de)(de)(de)話，通(tong)常(chang)(chang)效(xiao)果(guo)(guo)器(qi)上(shang)都(dou)(dou)會有標明(ming)。

3、然后來看電源上面標明的規格

一款SPOT效果器(qi)專用電(dian)源，輸入的(de)規格(ge)是(shi)100-240V，也就是(shi)說(shuo)是(shi)從100V到240V電(dian)壓都可使用，后(hou)面的(de)50/60HZ以及(ji)0.35A這個可以不看(kan)。輸出(chu)(chu)規格(ge)是(shi)9V DC，直流，輸出(chu)(chu)電(dian)流最大可以達(da)到1700毫安，因此它可以為(wei)多塊效果器(qi)提供(gong)電(dian)源，極性是(shi)外正(zheng)內負。
