救命!!!!!!!

原来的A501套件买了好久,工作忙一直没时间装,快10.1了,打算用假期装上,今天搭棚焊完分频器,接上试听,发现高音不响,就换了个2寸小纸盆喇叭,小纸盆喇叭响,感觉不对就用表量了下高音,发现是断路,另外一没问题.
今天可是才第二次打开包装,第一次上电,不会这么衰吧……
把电路图和我的连接图贴上来，高手给看看是哪里的问题吧

分频器高音出 口.'+.-.'并联47欧5W电阻1枚.搞好.无问题.分频器 高音原理图线路好象是仿ProAc.Response.2.5原理图,6欧可用5W.

我实在是看不出有何问题会引起喇叭烧坏！

烧了也应该出点味吧

再有小功率公房很容易烧高音[em11]

第一个原理图没问题。但是第二个是否是你搭棚的线路？出错了。你对照一下吧。

上啊

wangfan430

顶啊

刚才功率也不大
总共3、4W的样子
高音还串了电阻
就算输入全频也不应该出问题啊

谁还有这个高频啊
我要求1只
