Troubleshooting
The Sunre Subwoofer is expertly
designed and built to provide years of
trouble-free performance. Most prob-
lems that occur can usually be solved
by checking your setup or making sure
that the components connected to the
amplier 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
still persists, please contact your Sunre
Dealer for assistance.
Not enough bass
Check that your preamplier’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 preamplier has a single sub-
woofer/LFE output jack, try using a Y
cable to connect it to the left and right
inputs.
Make certain the subwoofer is in a cor-
ner location, ring 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 ring into one of
the walls, leave three inches of clear-
ance between the driver and the wall.
Home Theater preampliers 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 preamplier 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 preamplier’s subwoofer/LFE
output has an adjustable crossover
frequency, make sure that the Sunre
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 preampliers 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 speak-
ers can be redirected to play in the
subwoofer, or the subwoofer can play
the bass from all the speakers, in addi-
tion to its dedicated LFE (low frequency
effects) channel. Make sure that all of
the bass management options are cor-
rectly set. The preamplier may have a
way of turning the subwoofer output off
entirely, so check that it is always on.
Check that the preamplier 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
preamplier is correctly set to decode
the 5.1 surround modes, such as Dolby
Digital or DTS.
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.
