Troubleshooting
This subwoofer has been designed and
built
to provide years
of
trouble-free
per-
formance. Most
problems
that occur can
usually
be
solved by checking your setup,
or by making sure that the components
connected to the
amplifier
are on and
fully
operational.
The following information
will help
you
deal
with common problems you may ex-
perience during normal
use.
If a
problem
persists,
please
contact your
Dealer for
assistance.
Not enough bass
• Check that your processor's outputs are
connected to the subwoofer's
line-level
inputs and not to the
line-level
high pass
outputs.
If they are connected to the out-
puts by mistake, the bass
will
be weak but
the subwoofer
will still
function.
• If your processor has a
single
subwoofer/
LFE output jack, make sure it connects
to the subwoofer's Left input.
If
the bass
is
still
not enough after checking
all
the
remaining points, use a
Y cable
to connect
the processor's
single
subwoofer/LFE out-
put to the subwoofer's
left and right inputs.
• Try moving the subwoofer to a different
location. See
Location
on
page 10.
Plac-
ing it in a corner
will
maximize the bass
output and give the smoothest possible
response.
•
Home Theater processors
usually
have a
way
of
adjusting the
level
of
the sub-
woofer/LFE output, either using a remote
control
or
with a
small volume
knob
on
the
back panel.
Make sure that this is adjusted
correctly.
•
Check that your processor or receiver's
sub output
is
turned on.
Some
systems
only
have a sub output
signal
when the
front speakers are set to
"small."
• If
the processor's
Sub/LFE
output has an
adjustable
crossover frequency, make
sure that the subwoofer's own crossover
point is set to Bypass or part of the bass
range may be missing.
Not enough bass
in
a
5.1
system
•
5.1
Home Theater processors usually
have a bass management system which
allows
the
bass to be redirected among
your speakers. For
example, the bass nor-
mally
present
in
the front speakers can be
redirected to
play
in
the subwoofer, or the
subwoofer can play
the bass from
all
the
speakers,
in
addition to its dedicated LFE
(low
frequency effects)
channel.
Make
sure that
all
of
the bass management op-
tions are
correctly
set. The processor may
have a way
of
turning the subwoofer out-
put off
entirely,
so check that it
is
always
on.
•
Check that the processor
calibration
pro-
cedure
is
correctly
adjusted. Usually, the
preamp will
send a test tone through
all
the speakers
in
your system,
allowing
you
to adjust (trim) the
volume
of
each
channel
until
they are all playing
at the same level.
• If
the bass
is
weak only when playing
5.1
surround sources, check that your
processor
is
correctly
set to decode the
5.1
surround modes, such as Dolby Digital
or
DTS.
• Some
DVD discs have a menu which
allows you to select
which soundtrack to
play.
Check that the correct
5.1
surround
audio soundtrack
is
selected,
otherwise it
may just
play stereo into your preamp and
you won't get the true LFE
signal
into the
subwoofer.
