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.
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 S412PII
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 S412PII
amplifier panel. For initial
setup, you should set the
level controls on both
speakers at minimum
(full counterclockwise
rotation). With 5.1, 6.1 or 7.1
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.
If you choose, you can use
the “Small” or “Narrow”
setting on your receiver.
In this case, all of the
information below 80Hz
will be fed to the LFE/
Subwoofer input on the
S412PII. Now the level
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 auto sensing by
choosing the auto position.
LED Indicators: When your
speaker is turned on but is
not receiving a signal, the
LEDs on the front of the unit
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.
