Troubleshooting
The Sunfire Subwoofer is expertly designed
and built to provide years of trouble-free
performance. Most problems that occur can
usually be solved by checking your setup or
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 experience
during normal use. If a problem still persists,
please contact your Sunfire Dealer for
assistance.
Not Enough bass
•
Check that your preamplifier’s outputs
are connected to the subwoofer’s
line-level inputs and not to the line-
level outputs. If they are connected to
the outputs by mistake, the bass will
be weak but the subwoofer will still
function.
•
If your preamplifier has a single
subwoofer/LFE output jack, try using
a "Y" cable to connect it to the left and
right inputs.
•
Make certain the subwoofer is in a
corner location, firing at 45 degrees
into the walls formed by the corner.
This is not absolutely essential, but will
maximize the bass output and give the
smoothest possible response. If you
place the unit so one of the drivers is
firing into one of the walls, leave three
inches of clearance between the driver
and the wall.
•
Home Theater preamplifiers usually
have a way of adjusting the level of the
subwoofer/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 preamplifier 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 preamplifier’s subwoofer/LFE
output has an adjustable crossover
frequency, make sure that the Sunfire
subwoofer’s own crossover point is set
higher or part of the bass range will be
missing.
Not Enough bass
in a 5.1 System
•
5.1 Home Theater preamplifiers usually
have a bass management system
which allows the bass to be redirected
among your speakers. For example,
the bass normally 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
options are correctly set. The
preamplifier may have a way of turning
the subwoofer output off entirely, so
check that it is always on.
•
Check that the preamplifier calibration
procedure 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
preamplifier is correctly set to decode
the 5.1 surround modes, such as Dolby
Digital or DTS.
•
DVD & blu-ray 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.
