I’m hooking the cable via variable out Not to a speaker terminal. If I wanted to do what has been suggested would a wire from the amp phono ground work but to what alternate ground?
Amp or Subwoofer causing Hum?
Recently (after Beryl) I noticed a strong hum coming through the subwoofer. I changed cables still hum. I disconnected the subwoofer cable from the amp no hum. I turned the sub on but turned the amp off still a hum. I switched the center tube position still hum. No noticeable hum from speakers. Sub hooked up to carable out. Used y splitter and single rca outlet hum consistent with both .
any thoughts or suggestions on what to do or which item to have checked out first?
