Stacking
Arrangements
If you are connecting
several
components
and plan to use a
component
rack, follow these general
rules when arranging
your
components.
•If the components
are arranged
horizontally,
allow at least an inch
or two of space between them so air
can circulate
freely.
This will also
provide
some space between
the
audio devices to minimize
interference.
• If components
are arranged
vertically
on shelves, place the
stereo amplifier
at the top so that
heated air rising from it will not
pass around the other components.
•Do not block the ventilation
holes in
the components.
If components
are
placed on rugs or deep-pile
mats,
the ventilation
holes in the bottoms
may be blocked
and overheating
could result.
• Some VCR's may cause
interference
in TV's.
When placing
a VCR under your TV, try to keep at
least 18 inches between
the bottom
of the TV and the top of the VCR.
If interference
is present when the
VCR is used on top of the TV or at
the 18-inch distance
below the set,
move the VCR beside the TV. If
moving the VCR does not solve the
interference
problem,
try plugging
the VCR into a different wall
socket.
Plugging in Power Cords
Do not plug any power cord into a
wall outlet until you are finished
making connections.
Many components
have "convenience
outlets" on their back panels so you
can plug power cords from other
components
into a "convenience
outlet" instead of a wall outlet.
Usually these outlets will be labeled
either "switched"
or "unswitched".
• If the outlet is labeled "switched",
that means power to the outlet will
be switched off when the
component's
power button is
switched off.
• If the outlet is labeled "unswitched",
that means power will always be
available
at that outlet, even when
the component
is turned off.
Depending
on the size of your system,
you may prefer to use an extension
cord or a "multiple
adapter"
to get
enough outlets for all your
components.
The power cords on your components
may be "polarized"
(one blade is
wider than the other).
Be sure the
extension
cord or multiple adapter is
also polarized.
The plug should fit in
the outlet only one way.
Turning Off Power Before
Connecting
Components
Always turn off power to all
components
before you connect or
disconnect
any cables.
This will
protect your components
from
possible
electrical surges that could
damage your equipment.
This is a good practice for all your
audio and video components-TV's,
VCR's, audio systems, computers,
etc.
Positioning
Cables to Avoid Hum
The possibility
of picking up hum
(interference
noise) in the audio/video
cables will be reduced if you keep
them away from the back of the TV.
Route the cables to the sides of the
TV's back panel instead of straight
down the middle.
All cable plugs should be firmly
seated in the jacks where they
connect to the equipment.
If a plug is
not connected
firmly, audio hum or
smeared video may result.
If your antenna cable is flat twin-lead
cable, try to keep it away from the
audio/video
cables as much as
possible.
Excess flat, twin-lead
cable
should be cut off instead of coiled
behind the TV. Round, coaxial,
antenna cable is usually shielded and
can be coiled or placed next to
audio/video
cables without causing
interference.
