Eliminates Electrical Noise from the Power Line -
One of the most common (and easily correctable) problems that may adversely affect X10 signals is electrical "noise," or interference. The more interference there is on the power line, the more difficult it is for X10 receivers to detect signals from X10 controllers. It's like trying to have a conversation in a room when the music is playing too loud. But the FilterLinc Plug-In Noise Filter blocks that interference, preventing it from polluting the power line. Common sources of interference include refrigerators, freezers, plug-in fluorescent fixtures, aquarium filters, fountains, low-voltage lighting, fans, or anything with a motor.

Prevents X10 Signal Absorption -
Another common, yet easily correctable, problem affecting X10 signals is signal attenuation, or absorption. Because some devices are built with power supplies that kill noise on the AC line—and they often mistake X10 signals for noise—these devices may absorb X10 signals before their arrival at the receiving module. But the FilterLinc Plug-In Noise Filter eliminates those obstacles by blocking X10 signals from getting to them in the first place. The most common sources of signal attenuation include computers and audio/video equipment, particularly big-screen TVs.

Feed-Through Outlet for Added Convenience -
The FilterLinc Plug-In Noise Filter also offers several new features that have never been available on plug-in noise filters, like a feed-through outlet that prevents you from having to unplug the filter anytime you're looking for an available plug. Plus, the plug-in noise filter's high 49.4dB attenuation at 120kHz provides maximum protection at the X10 120kHz frequency. The plug-in noise filter is fully compatible with FM intercoms and Home PNA devices. The FilterLinc Plug-In Noise Filter is also safety tested and approved to ensure the highest degree of protection.
