I live in an older apartment. However, when my refridgerator turns on/off it causes a pop noise in my monitors. I don't think the outlets are grounded and it would take Major work to rewire the apartment. Are there any quick fixes? I've tried surge protectors etc. Should I be more concerned with the outlet the Refridgerator is plugged into or the outlets my gear is plugged into??? Like I said I use surge protecters, someone else said I should get a UPS...However, it looks to be the same as a surge protector with battery backup. Someone else said I could get a Noise filter...???? Any suggestions??
