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.

Removal Replacement
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.

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
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
better-quality 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 Left-
channel 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.
Attaching the speaker stands
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 spacer on the speaker stand.
In addition to the sound quality improvement, attaching the spacers
also provide non-sliding and stabilizing effects for the speaker
cabinet.

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。

安放
安装扬声器系统的房间的结构、面积，以及家具的摆放位置和尺寸都
将对扬声器系统再现音响的音质有显著的影响。为了获得最佳的音质，
请遵守下列注意事项。
●
请勿将扬声器系统安放在凸出的物体如水泥砖上。相反，应将其安放
在振动最小的牢固平面上。注意，如果扬声器系统安放不稳，将不能
得到高质量的低音。一般而言，与直接安放在平面上相比，将扬声器
系统安放在几个支脚上能获得更佳的低音效果。另外，如果您感到系
统再现的低音太弱，请移动扬声器系统，使其离后面的墙壁更近。这
样，您就可以通过调节扬声器的位置来控制再现低音的强弱。
● 很多房间，其家具和墙壁会影响再现音响的音质。再现立体声音响
时，使左侧和右侧的扬声器安放在同样状态下将带来最佳的效果。
如果它们安放的状态截然不同，则将对左声道和右声道的平衡带来
不良影响。
● 扬声器系统理想的安放位置是：想象一个等边三角形，将左侧和右
侧的扬声器分别安放在底边的两端，理想的欣赏位置就在三角形的
顶点或稍微靠后一点的地方。
● 处在扬声器系统前方的光滑的门或墙壁可能会因声音的反射而导致
某些音响频段的共鸣。为了消除共鸣，可在门或墙壁前放置一些吸
音材料，如厚窗帘等。
安装扬声器架
请按下面图示，使用随附的螺丝加装扬声器架于每个扬声器的底台下。
为了更好的音质，我们建议您在扬声器架上加装随附的调整垫。除了
能改进音质外，加装调整垫能使扬声器底台有不滑动及稳固的效果。
扬声器前格板的安装和拆除
本扬声器系统使用可拆式前格板。安装和拆除的方法如下。
1. 用两手抓住扬声器前格板的底边，轻轻向外拉，将前格板的下
部拆开。
2. 用同样的方法，轻轻向外拉前格板的上边，将前格板从箱体上
拆下。
3.
装回前格板时，将突起部推入扬声器箱体的前格板安装插孔。
