What Is It?
The term "line noise" refers to random fluctuations - electrical impulses that
are carried along with standard AC current. Turning on the florescent lights overhead,
your refrigerator, laser printers, working near a radio station, using a power generator,
or simply working during a lightning storm can all introduce line noise into your systems.Ever notice the "snow" on your TV when you use a blender or a
hair-dryer? That’s line noise being sent back into your electrical system and up into
your TV.
What Can It Do?
Line noise interference can result in many different symptoms depending on your particular
situation. Noise can introduce glitches and errors into programs and files. Hard Drive
components can be damaged. Televisions and computer monitors can display interference as
"static" or "snow," and audio systems experience increased distortion
levels.
What Can I Do?
Tripp Lite Surge Suppressors, Line Conditioners and UPS units include special noise
filters that remove line noise. The amount of filtration is indicated in the technical
specifications for each unit. Noise suppression is stated as Decibel level (Db) at a
specific frequency (KHz or MHz). The higher the Db, the greater the protection. Be wary of
"surge/noise suppressors" that don’t provide this information!
Isobar surge suppressors take noise suppression to a new level with
their exclusive Isolated Filter Banks. These special banks prevent line noise
generated from one device from traveling through the surge suppressor to interfere with
other connected equipment. So if you use a laser printer (a notorious source for line
noise) you can connect it to the same Isobar that powers your computer without putting
your equipment in danger.


Tripp Lite Isolators, with their Faraday Shield design provide true line
isolation and exceptional line noise rejection - even at low frequencies where it is
difficult to control. Isolators eliminate the need for costly rewiring or dedicated lines
by providing clean, computer grade electrical current from even the "dirtiest"
power.
