你的1543是用了晶振的?
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。
调1543旁边的可调电阻
一些小问题
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
功放和耳机
9V和12V电池

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
用这种晶振效果好

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太好了,
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="" />天啊,洞洞板也可以搞得这么漂亮?高手啊高手!!!!
真是厉害啊,呵呵
meyas兄,洞板水平高哦,多谢了引线到运放的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
好兄,听说cs8412容易坏的啊
楼上的厉害啊
来啦

meyas兄,
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
我已经插电焊了很多次啦,天啊,玩完了
请上论坛最终的版本图。钳版。
第一版的图在这!
论坛最终的版本直接把晶体设计进去啦!http://www.hifidiy.net/Article/Article.asp?articleid=19#
不是很大,就是晶震和cs8412的电源与1543的电源分开了
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
焊接时最好把电烙铁插头拔了,以防万一
