    我買了機用XLR綫駁去前級>XLR>後級>喇叭 發現只要插上其中一條XLR綫 係唔播聲時發現喇叭都會有會有嗚嗚聲發出，之後再用Rca綫駁另一套合併機出另一對喇叭都發現有嗚嗚聲，想問下其他師家有冇呢個情況？而用headphone或者用同軸／usb去cd 機再輸出前後級就冇呢個問題。

    Ground loop問題，我的Neo X也是有碰到，先把機器的地線拿掉吧。

    但奇怪在我發現拔掉埋電源綫，只插RCA綫或XLR綫就會有嗚嗚聲，師兄你都係冇插電源線情況下都有嗎？宜家只用usb輸出去cd 機解碼再去前後級出喇叭先冇事。

    您可以先將前後級的地線也拿掉試試，先確認是不是這問題。
