Before turning on the amplifier’s power switch:
• Make sure that the positive (+) and negative (–)
speaker cables do not contact each other. Otherwise, a
short-circuit may occur, causing damage to the
amplifier.
• Be sure to connect the speaker cables with correct
polarity (connect the speaker’s positive (+) and
negative (–) binding posts with the amplifier’s
corresponding speaker terminals). Reversed polarity
results in impaired bass-range reproduction, causing
mislocalization of the sound image. Also, be sure to
connect the Right and Left speakers with the
amplifier’s corresponding speaker terminals.
• Pull lightly on the speaker cables to ensure that they
are connected firmly.
For better-quality sound, observe the following
precautions when you install the speaker system:
• Placing the speaker system on several small-diameter
supports generally results in better sound than placing
it directly on a wide installation surface. Also note
that high quality bass cannot be obtained if the
speaker system is unstably positioned. Always use
the spacers or thin metal discs (such as coins) to seat
the speaker stably.
• Place the Right and Left surround speakers in similar
conditions. If they are placed in extremely different
conditions, left right channel balance will be
adversely affected.
SKC-4800 Center Speaker
Place the SKC-4800 as close as possible to your TV set,
for example, above or below the TV set. Be sure to set
the SKC-4800 firmly on the TV set or other equipment
so that it cannot slip and fall. This is especially
important if you have small children. If the SKC-4800
is to be placed on a TV set, be sure that:
• The supporting area of the TV set is larger than that
of the SKC-4800.
• The TV set’s support surface is flat and level.
• The TV set is not placed on an unstable support.
SKR-4800 Surround Speaker
If the speakers are to be wall-mounted, make sure that
the walls are strong enough to support the speaker’s
weight. The weight that mounting screws can support
varies greatly depending on the wall material and the
position of the reinforcing ribs embedded in the wall.
Use the thickest and longest possible mounting screws
with mounting screw head diameters less than 8.5 mm
and shank diameters less than 3.5 mm (consult with
your interior designer or contractor).
Using spacers
Affix four of the supplied spacers to the SKC-4800/
SKR-4800.
In general, Braun tubes used for color TV sets, etc. are
extremely sensitive and can be affected even by the
magnetism of the earth. If a speaker system is used near
them, therefore, discoloration or distortion of pictures
will occur. Refer to the following precautions when you
use the speaker with TV sets.
For magnetic shielded speaker (SKC-4800):
The speaker is shielded to prevent discoloration. In
some situations, however, discoloration may still be an
issue, in which case you should turn off your TV sets,
wait 15 to 30 minutes, and then turn it back on again.
This normally activates the deg
aussing function, which
neutralizes the magnetic field, thereby removing any
discoloration effects. If discoloration problems persist,
try moving the speaker away from your TV sets.
For non-magnetic shielded speakers (SKR-4800):
Try moving the speakers away from your TV sets. If
discoloration should occur, turn off your TV sets, wait
15 to 30 minutes, and then turn it back on again. This
normally activates the degaussing function, which
neutralizes the magnetic field, thereby removing any
discoloration effects.
Your Onkyo speakers are finished with a very high
quality polymer laminate covering that serves to protect
the wood speaker cabinet.
Wipe the cabinet periodically with a dry, silicon-
embedded or plain soft cloth.
The covering may be cleaned with a soft cloth
moistened with water and a mild soap. Avoid the use of
furniture polishes or harsh cleansers. Use a soft brush or
hand vacuum cleaner to remove dust and lint from the
grille material.
