喇叭訊號聲

kayulai

今晚在家中欣賞周星馳的功夫，
看罷已是深夜，四周無人，
當我行近AV櫃，準備關掉個AMP時，
由於喇叭好近，竟然聽到喇叭傳出微弱的訊號聲，
想問各位師兄，這是否正常？

我的5.1組合是這樣:Oppo93 - onkyo - front speakers preout from onkyo to naim

感謝各位師兄！！

    試o下重新插拔和檢查所有過機訊號線有否問題,如果只是電流聲可試o下更換一條有屏蔽接地的電源線

我用Naim嘅喇叭線，
AV櫃後有好多線材，
喇叭線會否受干擾？

另如果不是接線問題，如何檢查得知訊號聲嘅來源？
又有無有屏蔽電源線介紹呀？

noise will cause by many different way.
1.check independently when amp turn on (BDP off), turn to a higher vol to test
2. don't let the power cable/internet cable lay across or too close to the speaker cable (i know it is difficult but try to seperate)
3. check if it cause by your 30A, change the position to test.

Many thanks, Ching!

I checked the system already.
I found the noise made from the Naim amp.
No noise when I turn off the Naim.
What can I do?

kayulai

Any Ching can help?
I also change the speakers' cables. Still have the noise?
What can I do?
