SPEAKER PLACEMENT
Proper placement of your
speakers is an important step
in obtaining the most realistic
soundstage possible. These
recommendations are for the
optimum placement of your
loudspeakers. Use these
placement recommendations
as a guide. Slight variations
will not diminish your
listening pleasure.
The Studio Series S-CENTERII
loudspeaker is video-
shielded and can safely be
placed near a television.
The S-CENTERII is designed
to complement all of the
Studio Series loudspeakers.
It is the ideal way to re-create
the cinematic experience in
your home.
The supplied self-adhesive felt
pads may be attached to the
bottom corners of your
S-CENTERII speaker to protect
your television or furniture.
CONNECTIONTIPS
SPEAKER CONNECTIONS

Speaker Outputs

Speakers and electronics
terminals have corre-
sponding (+) and (–)
terminals. It is important to
connect both speakers
identically: (+) on the speaker
to (+) on the amplifier and (–)
on the speaker to (–) on the
amplifier. Wiring “out of
phase”results in thin sound,
weak bass and a poor
stereo image.
With the advent of
multichannel surround sound
systems, connecting
all of the speakers in your
system with the correct
polarity remains equally
important in order to
preserve the proper
ambience and directionality
of the program material.
To use the binding-post
speaker terminals, unscrew
the collar until the pass-
through hole in the center
post is visible under the
collar. Insert the bare end of
the wire through this hole;
then screw the collar down
until the connection is tight.
The hole in the center of
each collar is intended for
use with banana-type
connectors.

If there is no sound from
any of the speakers:
•Check that receiver/
amplifier is on and that
a source is playing.
•Review proper operation
of your receiver/amplifier.
If the system plays at low
volumes but shuts off as
volume is increased:
•Check all wires and
connections between
receiver/amplifier
and speakers.
•Make sure all wires are
connected. Make sure none
of the speaker wires are
frayed, cut or punctured.
•If more than one pair of
main speakers is being
used, check the minimum
impedance requirements of
your receiver/amplifier.
If there is no sound from
the center speaker:
•Check all wires and
connections between
receiver/amplifier and
speaker. Make sure all wires
are connected, and that
none of the speaker wires
are frayed, cut or punctured.
Make sure no wires are
touching other wires or
terminals and creating a
short circuit.
•If your receiver/processor
is set in Dolby* Pro Logic*
mode, make sure the center
speaker is not in phantom
mode.
•If your receiver/processor
is set in Dolby Digital or
DTS®mode, make sure the
receiver/processor is
configured so that the
center speaker is enabled.
