POLK AUDIO HISTORY—A PASSION FOR SOUND

Audio has built a reputation as “The Speaker Specialists.” Polk products are sold throughout the USA, Canada and in

SAFE LIMITS OF
OPERATION
Your Polk loudspeakers are made with the
highest quality materials for years of trouble-free performance.
However, damage to
loudspeakers can
occur when an amplifier, regardless of its
wattage, is made to
play at higher listening
levels than its power
can clearly produce
(usually beyond the “1
to 2 o’clock” position
on the volume control). This results in
very high levels of
audible distortion,
originating in the amp-
, that can add a
lifier
harsh, gritty sound to
music. Contrary to
popular belief, a
speaker is more likely
to be damaged by tr
ing to get too much
volume from a low-
ed amp or
power
receiver than from a
high powered one.

PLACEMENT RECOMMENDA
FOR THE CS
i SERIES CENTER CHANNEL LOUDSPEAKER
The CSi Series Center Channel Loudspeaker incorporates the most effective magnetic shielding available so it can be
placed safely on or near your TV or video monitor. If you notice video distortion or discoloration, immediately move the
speaker away from the TV and call Polk Audio Customer Service 800-377-7655 (9
polkcs@polkaudio.com. The most popular placement for a center channel speaker is on top of your TV, anchoring the
dialogue and effects to the screen
using a front projection TV system, place the center channel speaker on a small stand or table immediately below the
bottom of the projection screen, or at ear level behind the screen if your screen is acoustically transparent. Consult the
owner’s manual for your screen. Adhesive rubber feet are included with your CS
be attached to the bottom of the speaker to protect your furniture and keep the speaker in place.
PROCESSOR MODE CONFIGURATION
FOR THE CS
i SERIES CENTER CHANNEL LOUDSPEAKER
The “bass management” or “speaker configuration” menus of most surround receivers offer the choice of “normal” or
“wide” modes for center channel operation. In discrete channel digital processors these modes are referred to as
“small” and “large.” Normal (small) mode filters bass frequencies from the center channel speaker and sends them
instead to the front left & right main speakers or to the subwoofer output (LFE) jack. Wide (large) mode sends an
unfiltered, full range signal to the center channel speaker. Use the Small (normal) mode for optimum center (and
surround) channel performance and reliability.
CONNECTING YOUR CSi SERIES LOUDSPEAKER
[FIGURE 2]
e recommend 16-gauge or larger speaker wire. Follow the hookup directions included with your receiver. Strip 1/2 inch
W
(12.7mm) of insulation from each of the two conductors of the wire to expose the bare metal and twist each of the
individual conductors into single unfrayed strands. Note that one of the terminals on the rear of each speaker is red (+)
and the other is black (-). Make certain that you connect the wire from the red (+) terminal of your amplifier or receiver to
the red (+) terminal on your speaker and the wire from the black (-) terminal of your amplifier or receiver to the black (-)
terminal on your speaker. Most wire has some indicator (such as color-coding, ribbing or writing) on one of the two
conductors to help you maintain consistency.
