扁,431不装也能出声呀!

我这只8412以前用在其他DAC上也一样.

以下是引用wongkm33在2004-12-8 16:16:00的发言：
兄台没有装TL431呀，可能是CS8412缺少5V电源供应吧。
线材我不懂，不好评论。

用LM317作灯丝稳压比7805加两个二极声音胜在哪里?

从图左下角看，

请教wongkm33老兄两个问题:

1:我这只8412为何不能直接输入数码信号,而要加个74HCU04整形缓冲放大才行?



2: 这条超时空数码线如何?<img src="attachments/dvbbs/2004-12/200412816835128.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/2004-12/200412816835128.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />

我煲练几天，用靓胆试听，声音非常出色。

发觉用2uF油浸电容作输出更妙；声音较厚、较甜，低频有振延效应，有点象在音乐厅里享受音乐。

去买了一个TUNGSRAM的E88CC.

以下是引用HQ在2004-12-8 15:27:00的发言：
去志X买只得律风根E88CC试下啦.听讲好正播.
据传拍得住德律风根,有小德律风根之称.我试过还可以.另一个原因是没米啊!我买这个都要80米啊!如果买德律风根的话!唉!X根都赤埋啊!志X的DD都是杀人的价位啊!你看那毒喇叭,在香港都炒上了天.

调整可变电阻，电压可从3V到8V，或范围更大一些也可以。

变压器分离的另一个优点就是:
音乐背景更加宁静,声音更加纯正.音染大为减少.这一点实在难能可贵.是换其他补品难以做到的.


跟小鬼头学了一句:"信者得救.阿门!"

请注意我的前提是,已把4个电感换成磁芯加屏蔽的.

HQ 发表于 2004-12-8 13:20

今天作了试验.

把变压器令装在一个电脑电源箱内.把音量调尽.离喇叭处20CM听不到交流声.

而且声音效果又有不少改善.<img src="attachments/dvbbs/2004-12/2004128131934734.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/2004-12/2004128131934734.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><img src="attachments/dvbbs/2004-12/200412813200157.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/2004-12/200412813200157.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
