HI SLAPPY, FIRST OF ALL IS THE HUM COMING FROM THE SPEAKERS OR A COMPONENT? IF IT IS COMING FROM SAY THE AMP OR PREAMP IT IS QUITE POSSIBLE THAT THERE IS A DC PROBLEM THAT'S CAUSING THE TRANSFORMER TO HUM. FOR MONTHS, I HAD A HUM PROBLEM WITH MY PIONEER SX-1980 RECEIVER. MY HUM WAS LOUDEST WHEN STREET LIGHTS WERE ACTIVATED. DUKE POWER CAME OUT AND CHECKED THE STREET LIGHT/S CLOSEST TO MY HOUSE AND COULD NOT FIND ANY PROBLEM. POWER CONDITIONERS HAD ABSOLUTELY SO AFFECT ON THE HUM. AS A LAST RESORT, I DECIDED TO TRY THE HUMBUSTER FROM PS AUDIO AND IT WORKED IMMEDIATELY. NO FURTHER PROBLEMS. HOPE THIS HELPS. KEEP ME POSTED.
Ground Loop Question
Just curious about this....
What exactly is a ground loop and why does it affect the stereo like it does? What exactly is happening to cause this? I'm a little rusty on electrical but i know the basics and terms. I would assume a ground loop is actually where a ground gets fed back into itself and maybe oscilates and causes the hum? or am i totally reaching here?
My buddy's ol man has a pretty decent mid-level system that is PLAGUED by this Hum. He has a MONSTER 3600 stage 3 power filter and the hum is still there.
Better yet, when he turns on the lights the hum gets WAY worse. (not a dimmer switch either) Normally i would attribute this to bad power, but shouldnt the stage 3 filter be clearing this? Does this sound like it could be a ground loop?
What are some common causes of ground loops and some common fixes?
