我的最新版1543

声卡一般是48kHz out，应该接接了晶振的1543不会响吧？

爆音应该是接了晶振的缘故，不接晶振电路不会有。

另外高音失真应该跟1543可调电阻有关，仔细调一下试试。

数字输出：黑金二
功放：健伍DC-3（110V，很旧款了）
耳机：DT990
试听碟：《MY DISC》
小问题：1。本底噪声比黑金要大3-4倍。2。左右偶尔出现轻微的劈啪声，好象烧木头。3。带有轻微的金属回声，好象劣质卡拉ＯＫ的混响。
各种大虾小虾不大不小虾请指点下吧

兄台的晶振哪里搞来的呀?稳压块和输出电容都好象换了好东东呀,介绍一下吧

高频段的破音和金属回音可能与钳板提供的晶振质量和稳压有关，反正我用晶振听起来效果还好的哦[em12]

经过屡败屡战、不屈不挠、披荆斩棘、翻雪山过草地，历尽千辛万苦终于把1543去势了（通俗的说就是切掉晶振），初步感觉到高频段的破音和金属回音都消失了，在此特别要感谢meyas兄、钳版、西风瘦马、击鼓传花、clj689、我的父母亲、我的朋友同事、发电厂的工人叔叔、种粮食的伯伯……（此处略去3000句废话和3001句不废话），看来晶振部分是有未完美的地方，钳版可否考虑完善一下呀？？？<img src="attachments/dvbbs/2005-4/200541105948136.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-4/200541105948136.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><img src="attachments/dvbbs/2005-4/2005411102745.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-4/2005411102745.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />

meyas兄，洞板水平高哦，多谢了[em11]
引线到运放的8跟线再短点，能否将板直接连在运方座上可能干扰会更小的吧[em12]

好兄，听说cs8412容易坏的啊[em07]

您的4片并联洞洞板是怎么布线的哦？能不能反过来照张像上来啊[em11]

这样的话两个电源都要接
如果要去掉晶震的话，可以试试把图中篮圈那个磁珠卸下来（相当于给晶震电路断电了，不知道这样行不行），当然最彻底的方法是割断黄圈中的两条线 [em11][em11][em11][em11]
焊接时最好把电烙铁插头拔了，以防万一
