SPECIFICATIONS
MAINTAINING THE APPEARANCE
OF YOUR PSW550
Your new speaker cabinet is finished
in gloss black veneer that can be
dusted or cleaned with a damp soft
cloth. Avoid harsh detergents and
cleaning fluids, they can permanently
damage your speaker’s finish. Vacuum
the grille to remove dust.
Q. “Why does my system hum?”
A. “It doesn’t know the words.”
This is what passes for humor in the
audio business. Here’s the real answer:
If you have any electrical (50/60Hz)
hum in your system you’re going to hear
it clearly as soon as you hook up your
subwoofer. Most hum problems are
caused by “ground loops.” That is, the
electrical grounds of the components in
your system are not at the same electri-
cal potential. A very common ground
loop source is cable TV. Disconnect the
coaxial cable from your TV and/or VCR.
If the hum goes away, the cable is the
ground loop villain. In that case you
need a 75 ohm ground loop isolator.
This device attaches to your coaxial
cable where it plugs into your VCR (or
television). They’re simple to install and
usually solve the hum problem. Find 75
ohm ground loop isolators at your audio
dealer, Radio Shack stores, or online
at http://polkaudio.tranguard.com/.
Ground loops and hum can also be the
result of faulty electrical wiring in your
home. Consult a licensed electrician to
evaluate and, if necessary, repair the AC
wiring in your home. Light dimmers also
tend to introduce noise into audio sys-
tems. Remove them.
