ADJUSTING YOUR SYSTEM
SUBWOOFER ADJUSTMENTS
Your Powered Subwoofer offers a range of setting options. We recommend the following
settings as starting points, but the settings that are best for you depend upon your speak-
er placement, electronics and personal taste. After you've become familiar with what the
settings do, experiment with alternate options to find the method that works best for
your system setup. You'll find an informative article on “Subwoofer Positioning and
Adjustment” in the set up section at: www.polkaudio.com/education/article.php?id=19.
Note: When you set up your subwoofer for the first time, you will probably
have to make adjustments several times before you hear what you personally
like. Start with the volume at 50%.
AC POWER CONNECTION AND AUTO ON/OFF
Your PSW Series subwoofer features auto on/off circuitry, marked “auto”
on the power switch, which automatically turns your subwoofer on when
it senses a program signal. We recommend the “auto” setting if your
subwoofer is always receiving power (ie, if it’s plugged into a wall outlet).
When no signal is present, the circuit turns the subwoofer off after 15 minutes.
If you are concerned about the brief delay between when the music starts and
when the subwoofer turns on, simply leave your subwoofer in the “On” position.
You may want to leave your PSW system unplugged during extended periods
of non use, such as during a vacation.
FINE TUNING YOUR SUBWOOFER
• Volume—Adjust by ear using a wide variety of CDs and video sources.
Adjust for deep, powerful bass without “boominess.”
• Low Pass—Note: This control does not operate when the subwoofer
is connected with Method #1 (LFE Input). This control adjusts the frequency
range over which the subwoofer operates. When using smaller main speakers,
the upper range of the control will probably yield the best results. With larger
speakers, the lower end of the control range will probably sound best, but
always let your ear be the final judge. If male vocals sound “thin,” turn this
control up until the voice sounds rich but not “boomy.” If male vocals sound
too “thick” or “chesty,” turn this control down until the voice sounds natural.
• Phase Switch—Sit in your favorite listening position. Play music (not a movie)
with a walking bass line. We recommend playing jazz or country music. Now listen
carefully for the point at which the subwoofer transitions to your main speakers.
This is the crossover point, and this point should be below the frequency of a male
human voice. Whichever phase setting sounds louder or fuller at the subwoofer’s
crossover (transition) point is the optimum setting. Sometimes no difference
will be heard.
