小弟之前的訊源是使用廉價的DVD播放機
擴大機是使用老綜擴SONY SL-EX7
播放出來的聲音也不致於有雜音的問題
日前購入了CD5003
搭配此擴大機卻有這樣的問題
直推耳機就沒啥問題
所以我在想應該是擴大機本身的問題
(本身底噪的問題就不談了)
目前壁插是沒做任何更換
換壁插有辦法改善嗎？
還是需要做什麼其他更換呢？
謝謝

這樣的邏輯並不能證明這不是CDP的問題
如果直推耳機是插在耳機孔,而不是後面的RCA輸出的話

更換壁插對雜音的問題也不一定有幫助
如果是兩腳的插頭就先逐一反過來插看看
其他...可能要慢慢找問題了

哈..沒錯
耳機孔和RCA輸出線路可能不同
再說下一級一個是低阻抗的耳機, 一個是高輸入阻抗的擴大機

可簡單地用二分法來排除問題
弄個ipod接擴大機試試看

抱歉...文章沒提到將CD5003 RCA到其他地方

剛剛又接了一下其他東西

我把我接過的方式以及哪項有問題列出來

DVD播放器 RCA OUT > SL-EX7 RCA IN > SL-EX7的耳機輸出 = 正常

DVD播放器 RCA OUT > SL-EX7 RCA IN > SL-EX7 RCA OUT > 組合音響AUX IN > 組合音響的耳機輸出 = 正常

CD5003 RCA OUT > SL-EX7 RCA IN > SL-EX7的耳機輸出 = 雜音

CD5003 RCA OUT > SL-EX7 RCA IN > SL-EX7 RCA OUT > 組合音響AUX IN > 組合音響的耳機輸出 = 雜音

CD5003 RCA OUT > 亞瑟綜擴 RCA IN > 亞瑟綜擴的耳機輸出 = 正常

CD5003 RCA OUT > 隨身耳擴 > 隨身耳擴的耳機輸出 = 雜音更多

DVD播放器 RCA OUT > 隨身耳擴 > 隨身耳擴的耳機輸出 = 正常

Victor JVC.XA-V80 > SL-EX7 RCA IN > SL-EX7的耳機輸出 = 正常

Victor JVC.XA-V80 > SL-EX7 RCA IN > SL-EX7 RCA OUT > 隨身耳擴 > 隨身耳擴的耳機輸出 = 正常

所以結論是搭配問題？

結論是 CD5003 RCA 比較容易出現雜音現象
而導致這現象的疑兇還可能包括你的耳機
因為雜音也可能是破音...

雖然不知道你是從那裡可以判斷是耳機問題
不過我可以肯定絕對不可能是耳機問題...

剛對擴大機做一下微調
發現果真是擴大機問題
目前已經解決了

因為5003發出的聲音不同
而導致"雜音"的出現...不一定是5003的錯
也可能是5003發出的音頻,突現了耳機破音的情況
所以我說疑兇應該也包括耳機在內才對
畢竟我們沒聽到系統發出的聲音

不論如何,問題解決就好,恭喜

Ooh child, there's some smooching going on in this episode and it's getting kinda hot in here. Miguel starts a short list for his and Dexter's side project. Ellen and Maria bond over some scotch. Camilla loses her battle with cancer, but in a good way. And Dexter has a nightmare, or is it a nightmare? "Body parts out in the open." Never a good way to wake up.

Miguel saves Ramon's derriere again by working out a deal not to have him thrown in the slammer for his latest bad judgment. Ramon begrudgingly puts his badge down. Is Miguel perverting law for his own benefit, as Ellen accuses him? He sure is getting out of hand. Now he wants Dexter to kill Cheung and Ellen Wolf. Who's next?

Ellen Wolf is bad to the bone, but only as far as doing her job well is concerned. She has it out for Miguel. But he has it out for her just as bad. "Keep an open mind about her," Miguel tries to convince Dexter that he should take care of Ellen.

Miguel blows up at Dexter for saying "no" to him about killing Ellen. Dexter thinks he's lost his best friend. We eventually see that Ellen has a conscience and Miguel comes around and all is well with the world

Laguerta's been looking very good lately. She's got a glow about her. I like that she has a friend in Ellen, even if Ellen is a bit of a wolf. (What a pun!)

Deb tells Anton that he needs to get out of town.

Houston, we have a problem!
