其實兩脚電都要分電相位, 我有架 100V Pioneer Head Amp, 一插入降壓牛就 Hum, 同用手摸落機度, 有啲走電咁, 將電插反轉插返就乜事都冇

師兄, 試過晒, 未能成功, 但始終估計是關av amp事, 謝謝各位的幫忙...

是Grounding问题。我以前有过同样的问题。看看我旧的post就知道。不必多买其它的东西，用一条便宜的十仔线把十仔连在av amp，但不要在av amp调十仔的设定，也就是说在av amp选调喇叭设定而已。牺牲掉sub的设定是值得的，因为这样你的喇叭和十仔已是一体，对看戏没大的影响。听歌只开integrated amp，因为十仔和喇叭已一体，声音会结实很多。grounding问题彻底解决。

I have "de de" sound also when av amp preout to int amp AV bypass.  I have tried a lot of ways, including ground the AV amp with the int amp, disconnect tv, FM ant still cannot help.  But when I tried to change a better cable of the connection of av amp to int amp, it helps obviously but there are still arround 40% "de de" sound.  Can your suggestion help in my case?  If yes, where can I buy this things.

Please help.

I sovled 80% of the "de de" sound by adding an isolator to the cable TV box.
