Tips to Read Before Connecting Components
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 VCRs 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.
Connecting Other Components
l\irning 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, VCRs, 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 eoiled behind the
TV. Round, coaxial, antenna cable is usually shielded and can
be coiled or placed next to audio/video cables without causing
interference.
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 “unswitehed”.
• 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 are “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.
Positioning Speakers to Avoid Interference
Placing external speakers with unshielded magnets too close to
the TV may result in the speaker magnets affecting the quality
of the picture. Such speakers should be located at least eight
inches away.
If unshielded speakers are too close to the TV, colored streaks
will appear along the sides of the picture. If this happens, turn
off the TV for several minutes while moving the speakers
farther away. Then turn the TV back on.
