Line conditioners
A line conditioner protects your system from the small fluctuations in voltage from an electrical supply. Most systems can handle this variation, called line noise, without problems. However, some electrical sources include more line noise than normal. Line noise can also be a problem if your system is located near, or shares a circuit with, a device that causes electromagnetic interference, such as a television or a motor.
