Connecting the Speakers
We have supplied you with 5 sets of audiophile-grade
speaker wire to connect your speakers. Each wire is
color coded just to make it easy for you to see which
wire is which at the subwoofer (amplifier) side. You
can use any wire on any channel. Use whatever length
makes sense for your set up and speaker placement.
You can temporarily (and safely) rest the subwoofer on
the grille-end to make it easy to see the terminals and
connect the wires.
*NOTE: Your wires may feature spade lug connectors,
or be “bare wire” terminated. Use appropriate hookup
method (either Fig. 2 or Fig. 3).
Front L&R Speakers
Use one of the supplied 20' (6M) speaker wires to
connect the Left speaker to the Left Front speaker
output on the subwoofer amplifier. One conductor of the
speaker wire is marked with a color insulator. Use that
conductor to connect the red (+) terminal of the speaker
to the red (+) Left Front speaker terminal on the
subwoofer amplifier. Use the speaker wire conductor
with a black insulator to connect the black (-) terminal
of the speaker to the black (-) terminal on the subwoofer
amplifier. Tighten the thumb nut by hand or with a 3/8"
nut driver.
DO NOT OVER TIGHTEN. Repeat for the Right Front
channel speaker.
Center Speaker
Follow the same procedure described above to connect
the center speaker to the Center Speaker outputs on the
subwoofer amplifier.
Surround L&R Speakers
Follow the same procedure described above to connect
the rear surround speakers to the Left Surround and
Right Surround speaker outputs on the subwoofer
amplifier. Use the 40' (12M) wires.
IMPORTANT NOTE: Be careful to maintain correct polarity on
all the speakers by always using the speaker wire with the color
insulator for the red (+) terminals and the black marked wire
for the black (-) terminals ON THE AMPLIFIER AND ALL
THE SPEAKERS. Failure to maintain correct polarity will result
in poor sound quality. Double check all connections before using
the system.
If the supplied speaker wire is not long enough, contact your
Polk Audio retailer for more high quality speaker wire. Use only high
quality 16 gauge or thicker speaker wire. Do not use lamp cord. Lamp
cord is not speaker wire, and your speakers will not light up.
Connecting to AC Outlets
If you are completely finished connecting all your source
components, your TV, and your speakers, now you can plug the
system into household 110-120 V, 60 Hz AC power outlets. You
must first connect the supplied AC power cord to the receptacle on
the rear panel of the subwoofer. Locate the Power switch on the
back of the subwoofer and set it to the “Standby” position. A small
pilot light on the bottom, front side of the subwoofer will glow red
indicating that the system amplifiers are plugged in and awaiting
a turn-on “order” from the preamp/processor. When the preamp/
processor is turned on, it will turn the amplifiers fully on and the
pilot light will glow green. If you will be away from home for an
extended period of time, turn the subwoofer power switch to “Off.”
