Installation
Observe the following general
precautions and read the safety
instructions on pages 2 and 3 before
using your Sunfire Subwoofer.
• Never open the cabinet or remove
the metal control panel as this
might result in an electrical shock
to you or damage to the unit.
• Protect it from prolonged exposure
to direct sunlight and other direct
sources of heat, such as heating
vents and radiators.
• To prevent fire or shock, do not
expose the unit to rain or moisture.
If fluid or a foreign object should
enter the unit, immediately turn off
the power and contact your Sunfire
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 floor.
• If you wish to place your woofer so
the drivers face the floor and
ceiling, 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 arrange-
ment will impart substantial house
and floor 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
absorbing low frequency rocking
energy, allowing it to adhere solidly
to the floor. To move the woofer
along the floor, rotate it onto one
edge and it will slide along easier.
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 at
least two inches away from any
walls.
The metal control plate serves as the
amplifier heat sink and also as a conduit
to remove internal heat to the outside
and into the atmosphere. It can reach
temperatures of 60 degrees C, which will
feel hot to the touch, using nerves of
flesh and blood as temperature sensors.
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 constructed.
AC Power Considerations
Ensure that the unit is plugged into an
outlet capable of supplying the correct
voltage specified 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.
NOTE: Never remove the ground
pin from any power cords. This is
very dangerous.
Route the power-supply cord so it is
not likely to be walked on or pinched by
items placed upon or against it,
especially at plugs, convenience
receptacles, 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 speaker’s magnet won’t distort the
colors of your TV picture or erase your
video tapes, audio tapes or computer
discs.
