Instruction Manual

Thank you for your purchase of the Onkyo speaker
system.
Please read this manual thoroughly before using it.
Following the instructions in this manual will enable
you to obtain optimum performance and listening
enjoyment from your new speaker system.
Please retain this manual for future reference.

Before using this unit

• The speaker cabinet is made of wood and is therefore
sensitive to extreme temperatures and humidity.
Avoid placing the speaker systems in locations
subjected to direct sunlight, or in smoky or in humid
places, such as near an air conditioner, humidifier,
bathroom, or kitchen. Doing so may result in damage
to the speaker.

• Place the unit on a rigid, level surface. Placing it on a
slanted surface or weak base not only may cause the
unit to fall, but also results in decreased sound
quality.

• Be sure to turn off your amplifier before connecting
the speaker system. Connecting them with the
amplifier's power on may result in damage to the
amplifier or the speaker system.

• Keep water or other liquids away from the unit. If
water is spilled into the unit, not only the unit but also
the speakers themselves may be damaged.

Precaution on use

• This speaker system can handle the specified input
power when it is used for ordinary music
reproduction. If the following abnormal signals are fed
to the speaker, however, an overcurrent may flow in
the internal circuits, causing burning or breakage of
the wires even if the input power is below the
specified rating.

1. Noise produced when FM station is not tuned in

2. Sound produced when fast-forwarding cassette

tape deck

3. High-frequency sound generated by an oscillator,

an electronic musical instruments, etc.

4. Oscillating amplifier signals

5. Special test signals produced by audio checking

CD, etc.

6. Sound produced when connecting or

disconnecting audio connection cables (Always
turn off the amplifier’s power before connecting or
disconnecting cables.)

7. Howling when a microphone is used

• Do not place magnetic objects such as screwdrivers
and iron parts near the tweeter since they use
speakers with strong magnets. Otherwise, the
objects may be attracted, causing injury or damaging
the diaphragm.

• 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 bass­range 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.

SKF-4600 Front speaker system

The sound quality a speaker system reproduces varies greatly
depending on the construction and area of the room where it is
installed, as well as the location and size of the furniture. For better­quality sound, observe the following precautions.

• Avoid placing the speaker system on an elevated object such as
on concrete blocks. Instead, place it on a rigid floor surface with
minimal vibration. Also note that high-quality bass cannot be
obtained if the speaker system is unstably positioned. Generally
speaking, placing the speaker system on several small-diameter
supports results in better bass than placing it directly on the
installation surface. Moreover, if you feel the bass reproduced by
the system is too weak, move the speaker system closer to the
wall behind it. You can thus control the strength of the reproduced
bass by the position of the speakers.

• In many rooms, the furniture and wall affect the reproduced sound
quality. For stereo sound reproduction, placing the Right and Left
speakers in the same condition produces the best results. If they
are placed in extremely different conditions, the Right- and Left­channel balance will be adversely affected.

• The ideal placement of the speaker system is as follows: Imagine
an equilateral triangle and position the Right and Left speakers on
both ends of the base. The ideal listening position is at or slightly
to the rear of the triangle apex.

• Glazed doors or surrounding walls in front of the speaker system may
cause the resonance of specific frequency ranges due to reflected
sound. To eliminate this resonance, place some sound-absorbing
material such as a thick curtain in front of the doors or walls.

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 cork 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-4600 Center Speaker

Place the SKC-4600 as close as possible to your television set, for
example, above or below the television set. Be sure to set the SKC­4600 firmly on the television set or other equipment so that it cannot
slip and fall. This is especially important if you have small children. If
the SKC-4600 is to be placed on a television set, be sure that:

• The supporting area of the TV is larger than that of the SKC-4600.

• The TV's support surface is flat and level.

• The TV is not placed on an unstable support.

SKM-4600 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 10 mm and shank diameters less than
4 mm (consult with your interior designer or contractor).

Attach the supplied speaker stand at the bottom of each speaker
cabinet using the supplied screws as shown in the figure below.
For better sound quality, you are recommended to attach the supplied
cork spacer on the speaker stand.
In addition to the sound quality improvement, attaching the cork
spacers also provide non-sliding and stabilizing effects for the speaker
cabinet.

Attaching and detaching the speaker grilles

This speaker system uses detachable grilles. Use the following
method to attach or detach the grilles.

1. While holding the bottom edge of the speaker grille with your both
hands, pull it gently toward you to remove the bottom of the grille.

2. In the same way, gently pull the upper edge of the speaker grille
toward you to remove it from the main unit.

3. To replace the grill, push the projections at the corners into the
grille plug holes on the speaker cabinet.

Use with a TV set

In general, Braun tubes used for color television 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. To allow use with color television
sets, etc., this speaker system is provided with magnetic shielding.
Even so, discoloration may still result, depending on the installation
environment. If discoloration occurs, turn off the power of the television
set, wait for 15 to 30 minutes and then turn it on again. This activates
the self-demagnetizing function of the television set, improving the
display condition. If discoloration persists even after performing this
remedy, move the speaker apart from the television set. Discoloration
may also be caused when a magnet or other magnetizing object exists
near the television because of the combined effect.

Speaker care

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.
