When an air conditioner cycles, there are relay contacts that are actuated. These relays commonly arc when they are actuating, whether opening or closing. The older they get, the more they arc. This arc throws wideband hash into the air and onto the power line. It is similar to a small arc-weld. This is very likely to be the culprit. You probably need better RFI/EMI protection/filtering in your system.
I have dedicated lines, but why is this happening?
When my central air kicks on, I hear a pop through each speaker.
Now the odd part is, I just started hearing this recently. I never remember hearing it for the first several months after I had the dedicated lines installed.
I have made several changes to my system recently that has taken the transparency of my system to a level I didn't think was possible, but I don't think that could explain why I am just now hearing the pops. Or could it?
But the primary question remains. Why is the air conditioning popping through my speakers when I have dedicated lines.
Could this be coming back through the main bus bar ground in my panel?
What would fix it?
I obviously know crap about this stuff.
