CONNECTION TIPS
SPEAKER-LEVEL CONNECTIONS
Your S412P II speakers
should be connected to your
receiver in two ways (at
speaker level and line level)
in order to achieve the best
performance, especially
when listening to program
material recorded in digital
formats, such as Dolby*
Digital and DTS.
®
Connect the left-front and
right-front speaker terminals
on your receiver or amplifier
to the 5-way binding posts
on the back of each S412P
II
speaker. Remember to
maintain the correct
polarities (“+” to “+” and
“–” to “–”). The S412P
II
uses
a red binding post for “+”
and black for “–”. These
connections will provide
full-range sound to all four
transducers, and you should
ALWAYS make these
connections.
If your receiver or amplifier
does not have a line-level
subwoofer output, then you
do not need to make any
other connections, and you
should skip to the section
titled “Amplifier Controls.”
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.
