SPEAKER CONNECTIONS
CONNECTION TIPS
MODELS: S310II, S312II
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.

These models feature four
rubber feet that enable
them to be placed on a
smooth-surfaced floor,
such as tile or hardwood.
Four metal spikes are
supplied for use when the
speaker is to be placed on
a carpeted surface to
decouple the speaker from
the floor and prevent
unwanted damping. To
insert the spikes, gently lay
the speaker on its side (not
its front or back) on a soft,
nonabrasive surface. Each
spike screws into the
threaded insert in the
center of each rubber foot.
Make sure all four spikes
are screwed in completely
for stability.
NEVER drag the speaker
to move it, as this will
damage the spikes, the
feet and/or the wood
cabinet itself. Always lift
the speaker and carry it to
its new location.
CAUTION: Floorstanding
(tower) loudspeakers have
a high center of gravity
and may become unstable
and tip over during
earthquakes or if rocked,
tipped or improperly
positioned. If this is a
concern, these speakers
should be anchored to the
wall behind them, using
the same procedures and
hardware customary for
anchoring bookcases and
wall units. Customer is
responsible for proper
installation and proper
selection of hardware.
The supplied self-adhesive
felt pads may be attached
to the bottom corners of
your speakers to protect
your furniture.
