AMPLIFIER CONTROLS
LFE Level Control: Allows
you to adjust the volume of
the low-frequency effects/
subwoofer channel to suit
your room acoustics or
tastes. However, it only
affects the LFE signal. If
you are not using the LFE
input, the LFE level control
will not operate.

subwoofer channel to suit
your room acoustics or
tastes. However, it only
affects the LFE signal. If
you are not using the LFE
input, the LFE level control
will not operate.
Configuring Your Receiver:
You should choose the
“Large” or “Wide” option
for the left- and right-front
speakers so that full low-
frequency information will
be sent to the S412P
speakers. Make sure that
you also configure your
receiver for “Subwoofer
On” or “LFE On.” In this
case, the LFE/Subwoofer
signal will consist only of
the .1 (bass) channel. The
LFE signal level can be
adjusted by using the
LFE level on the S412P
amplifier panel. For initial
setup, you should set the
level controls on both
speakers at minimum
(full counterclockwise
rotation). With 5.1 source
material playing, advance
the level controls on each
speaker slowly until the
desired amount of effects
channel is present. This
is a rather subjective
adjustment and should be
made using a variety of
program materials.

will be fed to the LFE/

control operates through-
out the entire bass
spectrum below 80Hz, not
just within the .1 channel
portion. This configuration is
generally unnecessary but,
in certain room-placement
conditions, it allows greater
bass-level control.

Power Switches: The main
“Power” switch is simply
marked “On” and “Off.”
Turn this switch on to
commence operation of
the powered amplifier
after you have plugged the
power cord into an AC
outlet. The second switch
is labeled “On/Off” and
has two positions. Placing
the switch in the “Auto”
position puts the amplifier
in Standby mode. In this
mode the speaker will be
able to automatically
sense an incoming signal,
which will trigger it to turn
fully on. The speaker will
also automatically switch
itself back into Standby
mode after approximately
10 to 15 minutes have
passed without its sensing
a signal. We recommend
that you leave this switch
in the “Auto” position for
most applications. If you
will be away from home or
not using your speakers
for an extended period of
time, you should turn the
speakers off by using the
main power switch. The
Manual position will bypass
the auto-sensing feature
and leave the amplifier on
until turned off with the
main switch or returned to

LED Indicators: When your
speaker is turned on but is
not receiving a signal, the
LEDs glow red to let you
know that your speaker is
plugged in. When the
speaker is receiving a
signal, the LEDs glow
green. We have provided a
convenient “Green ‘On’
LED” switch on the back
panel to allow you to shut
off the front LEDs should
they interfere with your
enjoyment of a movie. This
switch has no effect when
the LEDs are in red mode.

• If the wires are connected
properly, the confusion may
be attributable to the design
of your receiver/ amplifier.
Your unit may have inverting
inputs, which reverse the
polarity of the signal
between the inputs and
outputs of the amplifier. To
check if this is the case,
reverse the speaker con-
nections for ALL S412Ps in
your system (and disconnect
any other speakers in the
system) so that the
receiver/amplifier’s (+)
connector is connected to
each S412P’s (–) (black
stripe) speaker connector.
If you do this and the
S412Ps function properly
(bass increases as you turn
your LFE/Subwoofer level-
control knobs clockwise),
your receiver/amp uses
inverting inputs. This is not
a problem. Simply connect
all of the speakers in your
system the same way, with
the receiver or amplifier’s
(+) terminal to the speaker’s
(–) terminal, and the receiver
or amplifier’s (–) terminal to
the speaker’s (+) terminal.
