Speaker Wire running parallel to Household 120v
I have discovered an issue with my speakers (wired to 16 and 18 g) where I heard a slight hum during a scene that was simply not producing sound. I never gave it much thought and had always beleived that it was the media at fault or the fact that I had the volume so loud that I was hearing the elctric current humming through the speakers.
Well I had mentioned this during a conversation with a friend of mine who happens to be in the Audio business for the past 25 years and he told me to trace the speaker cables and make sure that any 120 volt wire running nearby (within 6 inches of the speaker wire) was not running parallel to the speaker wire. Sure enough I had my rear speaker wires running under the floor attached to the baement ceiling joists directly along-side an existing household 120v wire. I made the effort and moved the wiring away about 10 inches from the 120v wire and tested out this theory. To my surprise the hum effect was almost completely gone.
Thought I would share this fact and ask what everybody thought of this.
Attached is Phase 1 of my HT Project, I'll post proper when done.
Thanks
