DOLBY* DIGITAL OR DTS
(OR OTHER DIGITAL SURROUND MODE) CONNECTION

Use this installation method for
Dolby Digital, DTS or other dig­ital surround processors:

Use either the left or right line­level input jack for the Low­Frequency Effects channel; it
doesn’t matter which one you
choose.

DOLBY PRO LOGIC* (NON-DIGITAL) –LINE LEVEL

Use this installation method
for Dolby Pro Logic applica­tions (not Dolby Digital, DTS
or other digital processing),
where the receiver/processor
is equipped with a subwoofer
output, or a volume-controlled
preamp (line-) level output:

Use RCA-type interconnects
to connect the line-level
subwoofer outputs on your
receiver or amplifier to the
line-level inputs on the sub-

®

IMPORTANT: Make sure that
the LFE/Normal toggle switch
∞ is in the “LFE” position.
This will bypass the sub­woofer’s normal low-pass
filter, reducing the possibility
of signal degradation and more
accurately reproducing the
program materials. However, if
your receiver is passing a full­range signal through its sub­woofer output, place the tog­gle switch in the “Normal”
position, which will activate
the low-pass filter and protect

woofer. IMPORTANT: Make
sure that the LFE/Normal
toggle switch ∞ is in the
“Normal” position. This will
activate the subwoofer’s low­pass filter, protecting the sub­woofer from possible damage
and enabling it to operate most
efficiently by reproducing only
the low-frequency materials
that it is best at handling.

NOTE: If your receiver or
amplifier only has one sub-

the subwoofer from possible
damage. Connect this jack to
the LFE output or subwoofer
output on your receiver or
amplifier. Connect each
speaker to the corresponding
speaker terminals on your
receiver or amplifier.

Make sure that you have con­figured your surround sound
processor for “Subwoofer On.”
Also, remember to configure
your receiver for 5.1-, 6.1- or

7.1-channel operation as
appropriate.

woofer output jack, then you
will need to use a Y-connector
(not included). Plug the male
end of the Y-connector into
your receiver or amplifier’s
subwoofer output jack, and
connect each of the two
female ends to separate RCA­type interconnects. Finally,
plug the RCA-type intercon­nects into the line-level inputs
on the subwoofer.

Connect each speaker to
the corresponding speaker
terminals on your receiver
or amplifier.

Make sure your receiver or
processor is correctly config­ured to indicate that the sub­woofer is “On.”

Note for advanced users: If
your receiver/processor has
a built-in low-pass crossover
filter for the subwoofer output,
you may switch the LFE/
Normal toggle switch to the
“LFE” position to bypass the
subwoofer’s internal
crossover.

DOLBY PRO LOGIC (NON-DIGITAL) –SPEAKER LEVEL

Use this installation method
for Dolby Pro Logic applica­tions (not Dolby Digital, DTS
or other digital processing),
where the receiver/processor
does not have a subwoofer
output, or a volume-controlled
preamp (line-) level output:

Connect your receiver or
amplifier’s front left and right
speaker terminals to the left
and right terminals on the
subwoofer that are marked
“Speaker Level In.” Connect
the left and right terminals
on the subwoofer that are
marked “Speaker Level Out” to
the corresponding terminals on
the back of your front left and
right speakers.

Connect your receiver or
amplifier’s center, surround
and surround back speaker
terminals to the corresponding
terminals on the back of
your center and surround
speakers.

OPERATION

the L8400P subwoofer.

The subwoofer Level Control

Crossover Adjustments

The Crossover Frequency

subwoofer reproduces
If your main speakers can
comfortably reproduce some
low-frequency sounds, set this
control to a lower frequency
setting, between 50Hz and
100Hz. This will concentrate
the subwoofer’s efforts on
the ultradeep bass sounds
required by today’s films and
music. If you are using smaller
bookshelf speakers that do not
extend to the lower bass fre­quencies, set the low-pass
crossover control to a higher
setting, between 120Hz and
150Hz. This control is not used

Phase Control

The Phase Control § deter­mines whether the sub­woofer’s pistonlike action
moves in and out in phase
with the main speakers or
opposite the main speakers.
There is no correct or incor­rect setting. Proper phase
adjustment depends on sev­eral variables such as sub­woofer placement and lis­tener position. Adjust the

Phase switch to maximize
bass output at the listening
position.

Remember, every system,
room and listener is different.
There are no right or wrong
settings; this switch offers the
added flexibility to adjust your
subwoofer for optimum per­formance for your specific
listening conditions without

TROUBLESHOOTING

If you used the high-level
(speaker) inputs and there
is no sound from any of the
speakers:

•

Check that the receiver/

amplifier

is on and a source

is playing.

• Check that the powered
subwoofer is plugged into
an active electrical outlet
and is switched on.

• Check all wires and connec­tions between the receiver/
amplifier and the speakers.
Make sure all wires are con­nected. Make sure none of
the speaker wires are frayed,
cut or punctured, or touching
each other.

• Review proper operation
of your receiver/amplifier.

If there is low (or no) bass
output:

• Make sure the connections
to the left and right “Speaker
Inputs” have the correct
polarity (+ and –).

• Make sure that the sub­woofer is plugged into an
active electrical outlet and
switched on.

• Adjust the crossover point.

• Flip the Phase Control switch
to the opposite position.

• If you are using a Dolby
Digital/DTS receiver or
processor, make sure that the
subwoofer and bass manage­ment adjustments on the
receiver/processor are set up
correctly.

• Slowly turn the Level Control
clockwise until you begin to
hear the desired amount of
bass.

having to move your speakers.
If at some time in the future
you happen to rearrange your
listening room and move your
speakers, you should experi­ment with the Phase switch in
both positions, and leave it in
the position that maximizes
bass performance.

If you used the line-level
inputs and there is no sound
from the subwoofer:

•

Check that the receiver/

amplifier

is on and a source is

playing.

• Check that the powered
subwoofer is plugged into an
active electrical outlet and is
switched on.

• Check all wires and
connections between the
receiver/amplifier and the
subwoofer. Make sure all
wires are connected. Make
sure none of the wires are
frayed, cut or punctured, or
touching each other.

• Review proper operation of
your receiver/amplifier.

• Slowly turn the Level
Control clockwise until you
begin to hear the desired
amount of bass.

• Make sure that you have
configured your receiver/
processor so that the sub­woofer/LFE output is on.
