Important Safety Precautions!
1. Unpacking: 
Check the product care-
fully. If it has been damaged in transit,
report the damage immediately by calling
your dealer and/or the shipping company
that delivered it.
2. Connections: Whenever changing,
connecting or disconnecting signal or
power cables etc., always turn off all
equipment. This prevents transients from
entering the equipment and prevents
electrical energy from reaching you.
Keep all connections out of the reach of
children. Before moving the unit, be cer-
tain to disconnect any interconnection
cords with other components, and make
certain that you disconnect any powered
units from the AC outlet.

8. Accessories. To ensure proper opera-
tion and to avoid the potential for safety
hazards, place the unit on a firm and level
surface. When placing the unit on a shelf,
be certain that the shelf and any mount-
ing hardware can support the product’s
weight. Do not place this product on an
unstable cart, stand, tripod, bracket, or

service technician to perform safety
checks to determine that the product is in
proper operating condition.
14. Feet/Spikes. When positioning, or
moving this product ensure that is lifted
rather than dragged across any
floor/mounting surface. This will avoid
any damage to the floor/mounting sur-
face. Attention! Products and/or product
feet constructed of rubber or plastics
may, in seldom cases, react chemically
and discolor treated or non-treated
wooden surfaces if positioned without
15. Warranty: The following conditions
may result in a void product warranty:

17. Specifications: All product specifica-
tions/features are subject to change
without notification.
Passive Products:
18. Amplifiers: 
Amplifiers used to drive
these units must deliver a sufficient out-
put power. A lack of output power may
lead to amplifier-clipping, which causes
damage not covered by guarantee.
Active (Powered) Products:
19. Ventilation. 
Slots and openings in the
cabinet are provided for ventilation and
to ensure reliable operation of the prod-
uct and to protect it from overheating,
and these openings must not be blocked
or covered. The openings should never
be blocked by placing the product on a
bed, sofa, rug, or other similar surface.
This product should not be placed in a
built-in installation such as a bookcase or
rack unless proper ventilation is provided
or the manufacturer’s instructions have
been adhered to.
Make certain that the proper space
(more than 10cm) is provided both above
and below the unit for ventilation. If the
amplifier will be installed in a cabinet or
other enclosed area, make certain that
there is sufficient air movement within
the cabinet, with means provided for hot
air to exit and for cool air to be brought in.
Do not obstruct the ventilation slots on
the top of the unit or place objects direct-
ly over them. Remember, power ampli-
fiers generate heat, and the heatsink fins
and ventilation slots that form part of the
cabinet are specially designed to remove
this heat. Placing other electronic equip-
ment near these heat-dissipation systems
may possibly affect the long term reliabil-
ity of both your amplifier and the objects
placed above it.
Do not place CDs, record jackets,
owner’s manuals or other paper on top of
or beneath the unit or in between prod-
ucts containing amplifiers in a stack. This
will block the air flow, causing degraded
performance and a possible fire hazard.
20. Power Sources. This product should
be operated only from the type of power
source indicated on the marking label. If
you are not sure of the type of power
supply to your home, consult your prod-
uct dealer or local power company. For
products intended to operate from bat-
tery power, or other sources, refer to the
operating instructions.
21. Grounding or Polarization. This prod-
uct may be equipped with a polarized
alternating-current line plug (a plug hav-
ing one blade wider than the other). This
plug will fit into the power outlet only one
way. This is a safety feature. If you are
unable to insert the plug fully into the out-
let, try reversing the plug. If the plug
should still fail to fit, contact your electri-
cian to replace your obsolete outlet. 
Do not defeat the safety purpose of the
polarized plug.
CAUTION: To prevent electric shock,
 do not remove the grounding plug 
on the power cord, or use any plug 
or extension cord that does not have 
a grounding plug provided. 
Make certain that the 
AC outlet is properly grounded. 
Do not use an adapter plug 
with this product.
The lightning flash with arrowhead 
symbol, within an equilateral triangle, is 
intended to alert the user to the 
presence of uninsulated “dangerous 
voltage” within the product’s enclosure 
that may be of sufficient magnitude to 
constitute a risk of electric shock to 
The exclamation point within an 
equilateral triangle is intended to alert 
the user to the presence of important 
operating and maintenance (servicing) 
instructions in the literature 
accompanying the appliance.
22. Power-Cord Protection. Power-supply
cords should be routed so that they are
not likely to be walked on or pinched by
items placed upon or against them, pay-
ing particular attention to cords at plugs,
convenience receptacles, and the point
where they exit from the product. To
avoid safety hazards, use only the power
cord supplied with your unit. If a replace-
ment cord is used, make certain that it is
of a similar gauge. We do not recommend
using extension cords with this product.
As with all electrical devices, do not run
power cords under rugs or carpets or
place heavy objects on power cords.
Damaged power cords should be
replaced immediately, by a qualified ser-
vice technician, with cords meeting fac-
tory specifications. When disconnecting
the power cord from an AC outlet, always
pull the plug; never pull the cord. 
23. Non-use Periods. The power cord of
the product should be unplugged from
the outlet when left unused for long peri-
ods of time.
24. Lightning. For added protection for
this product during a lightning storm, or
when it is left unattended and unused for
long periods of time, unplug it from the
wall outlet and disconnect the antenna or
cable system. This will prevent damage
to the product due to lightning and
power-line surges.
25. Overloading. Do not overload wall
outlets, extension cords, or integral con-
venience receptacles, as this can result
in a risk of fire or electric shock.
26. Damage Requiring Service. Unplug
this product from the wall outlet and refer
servicing to qualified service personnel
under the following conditions:
a. The power-supply cord or the plug has
been damaged; or
b. Objects have fallen, or liquid has been
spilled into, the product; or
c. The product has been exposed to rain
or water; or
d. The product does not operate normally
when following the operating instruc-
tions. Adjust only those controls that
are covered by the operating instruc-
tions, as an improper adjustment of
other controls may result in damage
and will often require extensive work
by a qualified technician to restore the
product to its normal operation; or
e. The product has been dropped, or the
enclosure damaged; or
f. The product does not appear to operate
normally or exhibits a marked change in
27. Servicing. Do not attempt to service
this product yourself, as opening or
removing covers may expose you to dan-
gerous voltage or other hazards. Refer all
servicing to qualified service personnel.
28. Object and Liquid Entry. Never push
objects of any kind into this product
through openings, as they may touch
dangerous voltage points or short-out
parts that could result in a fire or electric
shock. Never spill liquid of any kind on
the product. The apparatus shall not be
exposed to dripping or splashing and no
objects filled with liquids, such as vases,
shall be placed on the apparatus.
29. Heat. The product should be situated
away from heat sources such as radia-
tors, heat registers, stoves or other prod-
ucts (including amplifiers) that produce
heat. Avoid installation in extremely hot
or cold locations, in an area that is
exposed to direct sunlight or near heating
equipment. When positioning the product
in its final location, make certain that it
has adequate ventilation on all sides, as
well as on the top and bottom.
