各位師兄,我發現用紅白RCA cable,啲聲未開機已聽到好大boo聲,但啲RCA cable 質素好啲,啲聲就細啲,何解{:1_336:}

Thanks a lot for all c hing's advice! 我終於發現係當我由電視駁hdmi去blueray player or media player,而這兩部player 係用同軸駁去部AV amp的, 咁就有boo 聽啦,請各位師兄指點迷津{:6_194:}

TV ---->HDMI ----> player ----->同軸---->AV AMP(have boo sound)
                           player ----->同軸---->AV AMP(without any boo sound)
最終結果係大廈天綫因起{:6_199:} 我disconnect the RF cord 就乜聲都冇啦,咁就係買舊isolator,但係啲舊文話加咗會影響電視接收,甘我一定俾隻老虎殺死,點算{:6_197:}

    I believe add isolator will not affect TV receive too much, don't worry.......{:6_142:} {:6_142:}

Thanks a lot for your comment{:6_193:}
我今天已跟舊post加水缐由TV的RFcord去排蘇(接頭用美式插頭),效果真係減左90%.
如果加isolator 會否可以減到100%架? 同時有乜好介紹{:6_190:}
