你個case我既睇法同ground loop無直接關係, 反而, 你可以諗下是否訊號方面的問題。我而家都用緊7000d, 早輪都曾經有類似問題, 經搜集資料後認為係同天線訊號有關係。當時, 我是由3000d升級上7000d, 接駁方法沒改變, 後來得知7000d接收訊號的能力較差, 結果去鴨記買左個天線放大器, 接駁後就解決了問題了。
希望幫到你。

不錯, 用isolator的效果會更加好, 此類hum聲應不會對器材造成損害。

我用了後發覺聲畫都不覺有分別, 我用緊supra既isolator, 直接去威達買還比鴨記永盛平少少。

得一款啫, 大約3xx到。用後可減低90幾%的hum聲, 唔行埋個喇叭基本上聽唔到hum聲了。
