Onkyo SKS-4700 User manual

En
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 instrument, 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.

Surround speaker system SKM-4700 ×2
Connections
● Turn the sound volume to the minimum and disconnect the power
cord from the amplifier before connecting the speaker cables.
● The nominal impedance of this speaker system is 8 Ω. Use
only amplifiers capable of handling this impedance.
● Use the supplied speaker cables to connect between speaker’s
input terminals and the amplifier’s speaker
terminals as illustrated on the right.
● Connect the speaker cables securely to the
terminals, with the core wires twisted
properly. In this case, make sure that the
core wires do not touch each other. Note
that a short circuit in core wires may result
in damage to the amplifier.

SPEAKER SYSTEM
Connecting to AV amplifier
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.

Placement
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-4700 Center Speaker
Place the SKC-4700 as close as possible to your TV set, for
example, above or below the TV set. Be sure to set the
SKC-4700 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-4700 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-
4700.
● The TV set’s support surface is flat and level.
● The TV set is not placed on an unstable support.
SKM-4700 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 9 mm and shank diameters less than 4 mm (consult with
your interior designer or contractor).
Using spacers
Affix four of the supplied spacers to the SKC-4700/SKM-4700.
Use with a TV set
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. To allow use with color TV 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 TV
set, wait for 15 to 30 minutes and then turn it on again. This activates
the self-demagnetizing function of the TV set, improving the display
condition. If discoloration persists even after performing this remedy,
move the speaker apart from the TV set. Discoloration may also
be caused when a magnet or other magnetizing object exists near
the TV set 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.

HOMEPAGE
作为电视机的外接扬声器使用时
通常，应用于彩色电视机等的阴极射线管是极为敏感的，它们甚至会
受到地球磁场的影响。如果扬声器系统靠近它们，则会产生色调混乱
或图像失真。为了能够和彩色电视机等同时使用，本扬声器系统进行
了磁场屏蔽。
但是，即使进行了屏蔽，根据安装的环境，也有可能发生色调混乱。
如果出现色调混乱，请关闭电视机的电源，等待15至30分钟，然后再
次打开电视机电源。这将启动电视机的自动消磁功能，改善显示状况。
如果在进行这种补救措施后仍有色调混乱，请将扬声器离开电视机远
一些。由于综合影响，当一块磁铁或其它磁性物体放置在电视机附近
时，也有可能出现色调混乱现象。
扬声器的维护
您的Onkyo扬声器表面覆盖了一层高质量的聚合物薄膜，以保护木质的
箱体。请定期用一块干燥的软硅布或普通软布擦拭机体。
其表面可以用软布蘸清水来擦拭，可以使用刺激性不强的肥皂。请不
要使用家具抛光剂或去污粉。请用软刷或手持型吸尘器去除沾在前格
板上的灰尘和绒毛。
