CONNECTION TIPS

Speakers and electronics
terminals have corre­sponding (+) and (–)
terminals. It is important to
connect both speakers
identically: (+) on the
speaker to (+) on the

SPEAKER-LEVEL CONNECTIONS

amplifier and (–) on the
speaker to (–) on the
amplifier. Wiring “out of
phase” results in thin
sound, weak bass and a
poor stereo image.

Your S412P 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 5.1
formats, such as
Dolby** Digital and DTS.
Connect the left-front and

4

right-front speaker
terminals on your receiver
or amplifier to the 5-way
binding posts on the back
of each S412P speaker.
Remember to maintain the
correct polarities (“+” to
“+” and “–” to “–”). The
S412P 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.”

LINE-LEVEL CONNECTIONS

Each S412P speaker is also
equipped with a line-level
Low-Frequency Effects
(LFE/Subwoofer) input for
superior performance with
digital 5.1 surround
formats. The .1 LFE
channel contains
additional low-frequency
information not found in
the left- and right-front
channels. The LFE input
works with the full-range
speaker-level input to
provide the dynamics and

effects that your favorite
filmmakers intended.
You will need to use a
Y-Connector (not included)
with one male connector
and two female connectors
to connect the line-level
subwoofer output on your
receiver/amplifier to the
LFE/Subwoofer inputs on
the S412P speakers. Plug
the male connector into
the subwoofer output on
your receiver or amplifier,
and connect each of the

two female connectors
to extension RCA patch
cords. Then plug each
patch cord into the
LFE/Subwoofer input of
the left and right S412P
speakers. Note: If your
receiver has separate
left and right line-level
subwoofer (or LFE) output
jacks, you do not need to
use a Y-Connector.

This area is designed to become quite warm

during normal operation.

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 low­frequency 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)
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.

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

6

channel. The

S412P. Now the level
control operates through­out 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 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.

TROUBLESHOOTING

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 there is no sound coming
from one speaker:

• Check the “Balance”
control on your
receiver/amplifier.

• 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 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 (or low) bass
output:

• Make sure the polarities
(+ and –) of the left and
right “Speaker Inputs” are
connected properly.

• Make sure that the
speaker is plugged into an
active electrical outlet and
switched on, and that the
green LEDs are displayed.

If you used the LFE input
and there is no sound from
the subwoofer:

• Check that receiver/
amplifier is on and that a
source is playing.

• Make sure that the
speaker is plugged into an
active electrical outlet.

• Check all wires and
connections between
receiver/amplifier and
speakers.

• Make sure all wires are
connected. Review the
“Line-Level Connections”
section on page 5 of this
manual and make sure that
a single RCA patch cord
is connected to each
loudspeaker from the
Y-Connector plugged into
the receiver/amplifier’s
subwoofer output. Make
sure none of the speaker
wires are frayed, cut or
punctured.

• Review proper operation
of your receiver/amplifier,
including making sure that
you have configured your
receiver so that the sub­woofer output is active.

If you are using the S412P
LFE/Subwoofer input and
the bass level decreases
(instead of increasing)
when you turn the LFE/
Subwoofer Level knob
clockwise:

• Recheck to make sure
that your receiver or
amplifier-speaker outputs
are correctly connected to
the S412P speaker inputs
(gold-plated binding posts),
(+) to (+) and (–) to (–). The
S412P (+) terminal has a red
stripe and is located on the
right-hand side, below the
letter “L” of the molded JBL
logo, when looking directly at
the back of the S412P.

• 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 con­nections for ALL S412Ps in
your system (and disconnect
any other
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 level­control 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.
