Installation
Observe the following general pre cau -
tions and read the safety in struc tions on
pages 2 and 3 before using your Sunfi re
Subwoofer.
• Never open the cabinet or remove
the metal control panel as this
might result in an electrical shock to
you or dam age to the unit.
• Protect it from prolonged ex po sure
to direct sunlight and other direct
sources of heat, such as heating
vents and ra di a tors.
• To prevent fi re or shock, do not
expose the unit to rain or moisture.
If fl uid or a foreign object should
enter the unit, immediately turn off
the power and contact your Sunfi re
Dealer.
• Avoid excessive exposure to
extreme cold or dust.
• Do not place heavy objects on top
of the unit.
• Do not place the subwoofer with its
control panel against the fl oor.
• If you wish to place your woofer so
the drivers face the fl oor and ceil-
ing, thereby moving up and down,
use at least 1-1/2 inch high spikes
or feet for support. They may be
attached either with screws or self-
stick backing. This ar range ment will
impart substantial house and fl oor
shaking motion.
• Four extra heavy, shock absorbing
rubber mounting feet have been
included. If your woofer tends
to wander about slightly while in
use, place these feet just inside
the existing feet positions. These
shock absorbing mounts will let the
woofer rock freely, thereby absorb-
ing low frequency rocking energy,
allowing it to adhere solidly to the
fl oor.
Heat rise
• Allow adequate ventilation around
the metal control panel of the
subwoofer.
• Do not let anything come into
contact with the panel and keep it
at least two inches away from any
walls.
The metal control plate serves as the
am pli fi er heat sink and also as a conduit
to remove internal heat to the outside
and into the atmosphere. It can reach
tem per a tures of 60 degrees C, which
will feel hot to the touch, using nerves of
fl esh and blood as tem per a ture sen-
sors. As uncomfortable as it may feel, 60
degrees C cannot burn you, and in fact is
almost cool to copper, silicon, steel, and
aluminum, the materials from which your
woofer is con struct ed.
AC Power Considerations
Ensure that the unit is plugged into an
outlet capable of supplying the correct
voltage specifi ed for your model.
Unplug your subwoofer’s power cord
from the electrical outlet if it will be left
unused for a long period of time.
Route the power-supply cord so it is not
likely to be walked on or pinched by items
placed upon or against it, es pe cial ly at
plugs, con ve nience re cep ta cles, and the
point where it exits from the unit.
Magnetic Fields
We recommend that you place your
woofer further than two feet away from
your TV, VCR, tape deck or computer, so
the speak er’s magnet won’t distort the
colors of your TV picture or erase your
video tapes, audio tapes or computer
discs.
