Amplier Installation
Before using your subwoofer ampli-
er, please observe the following
general precautions and read
the safety instructions on page 2.
Also read the manual that came
with your Sunre HRSIW8 in-wall
subwoofer.
• The amplier may be rack mounted
using the supplied rack ears. It will
t into a standard 1U, 19 inch rack
space. Allow a minimum of 1 free
rack space above and below for
ventilation. This is very important.
• The amplier may also be placed
on a shelf, supported on its feet.
Make sure it is not placed on car-
peting or similar that may obscure
its ventilation openings.
• Never open the amplier cabinet
as this might result in an electrical
shock to you, or damage to the
unit. There are no user-servicable
components inside.
• Protect the amplier from prolonged
exposure to direct sunlight and
other direct sources of heat, such
as heating vents and radiators.
• To prevent re or shock, do not
expose the amplier or subwoofer
to rain or moisture. If uid or a for-
eign object should enter either unit,
immediately turn off the power and
contact your Sunre Dealer.
• Avoid excessive exposure to
extreme cold or dust.
• Do not place heavy objects on top
of the amplier.
Heat rise
• Allow adequate ventilation around
the top and sides of the amplier.
• Allow adequate ventilation if you
are rack-mounting the amplier.
AC Power Considerations
Ensure that the amplier is plugged into
an outlet capable of supplying the correct
voltage specied for your model.
Unplug your amplier’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, especially at
plugs, convenience receptacles, and the
point where it exits from the unit.
Before making or changing any
connections, ALWAYS make sure that the
amplier and your other components are
turned OFF. Also turn down the volume
control of the subwoofer amplier and
your preamplier or receiver.
Speaker Level connections
The amplier’s speaker level outputs
can accept speaker wires with banana,
dual-banana, bare wire, pins or spade
terminals. If you have banana type con-
nectors on your speaker wire, make sure
that you tighten the binding posts before
inserting.
Make sure that the negative speaker
wires never touch the positive wires as
this will short out and possibly damage
your amplier.
Magnetic Fields
We recommend that you place your
subwoofer further than two feet away
from your TV, VCR, tape deck or com-
puter, so the speaker’s magnet won’t
distort the colors of your TV picture or
erase your video tapes, audio tapes or
computer discs.
