Dedicated Lines - Problem


I recently installed 2 dedicated lines (I thought!) but have noticed a loud pop through my speakers when the air conditioner and de-humidifier automatically switch on and off. My panel is made up of double breakers, each breaker controlling 2 lines. The air conditioner and the de-humidifier do not share a breaker with the stereo lines. Any suggestions what is causing the popping noise ... obviously, the 2 stereo lines are NOT dedicated.

The people above are on the right track,having your new dedicated line tied to the same phase leg in your breaker box as your dehumidifier,and AC if that is the problem.If it is a 240 AC,the problem will still leak through since a 240 AC uses both halves of the power line.A 120 volt AC only uses one side of the 240 volt line.Even your neighbors lines are tied to the same power lines as most most likely. They're just further away and less noticeable.Even a dedicated utility transformer will still have other peoples appliance noise coming through.A good power condition might help out as the last resort.Try switching outlets, or phase sides as suggested above.Its hard to describe without drawing a diagram.We hope you get cleared up though.
