The AF310 is a Line Noise Attenuator
and filters noise from your power lines, without affecting the
X10 or A10 signal. It can therefore be installed anywhere in the
house. If you find that you have multiple sources of noise, a
great way to reduce general noise on the line is to install one
or more AF310 shunt filters around the house. The AF310 shunt
filters filter anything around the X10 signal, which can improve
the signal quality dramatically.
Example
We have seen a situation where several hundred electronic
ballasts were all creating noise that was roughly 90kHz and
down. The noise was close enough to the X-10 signal frequency to
interfere with the receivers but far enough away that three
shunt filters (one for the A leg, one for the B leg and a third
one for the C leg) cut the noise in an entire panel from 500mv
to less than 30mv. That’s better than trying to
install 300 blocking filters.
