systems where the 3dB boost is not
needed, this switch can be useful for
providing a quick boost for bass-shy
program material. Most people prefer
more bass output for movies than
music, so you can use this switch as a
handy way to adjust bass levels as you
switch between movie to music sources.
SWITCHABLE PHASE ALIGNMENT
(FIGURE 10)
Have someone else switch between
these two settings while you sit in your
favorite listening position. Use music
with good bass and a deep male vocal.
When you hear the best balance of deep
bass and natural lower octaves of the
male voice, you have achieved optimum
phase tuning.
MAINTAINING THE APPEARANCE
OF YOUR PSW650
Your new speaker cabinet is finished
in woodgrain vinyl that can be dusted
or cleaned with a moist soft cloth.
Avoid harsh detergents and cleaning
fluids, they can permanently damage
your speaker’s finish. Vacuum the
grilles 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 60Hz hum
in your system you are going to hear
it clearly once you hook up your sub-
woofer. Most hum problems are caused
by ground loops. That is, the electrical
grounds of the components in your
system are not at the same electrical
potential. A very common ground loop
source is cable TV. Disconnect the coaxi-
al cable from your TV 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 is
about the size of a pen and is attached
to your coaxial cable where it plugs into
your VCR (or television). You can
obtain this device from some audio
dealers, Radio Shack stores, Zantech
(1-800-843-5465), or Channel Plus
(1-800-999-5225).
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
systems. Remove them.

TECHNICAL ASSISTANCE
OR SERVICE
If, after following the hook-up direc-
tions, you experience difficulty, please
double check all wire connections. If
the problem is that you are not getting
enough bass, make sure the AC cord is
connected to a live AC power source and
that the power switch is set to the “on”
or “auto” position. Make sure that your
electronic equipment is operating cor-
rectly by hooking up another speaker to
the speaker output. Should you isolate
the problem to the speaker, contact the
authorized Polk Audio dealer where you
made your purchase. Authorized Polk
Audio dealers are the best source for
advice and assistance.
