7 Precautions for installation

• To avoid personal injury or accidentally
dropping the unit, have two persons
unpack, carry, and install the unit.

• Do not install the speakers on an uneven
surface or in a place subject to vibration;
otherwise, they may fall over, causing damage or injury.

– Take the occurrence of earthquakes or other physical

shocks into consideration when selecting the installation
place, and secure the speakers thoroughly.

• To prevent deformation or discoloration of the cabinet, do not
install the speakers where they are exposed to direct sunlight
or high humidity, and avoid installation near air conditioning
outlets.

• Speaker vibrations may cause howling. Place the speakers
as far away from the player as possible.

• The speakers are magnetically shielded to avoid color
distortions on TVs. However, if not installed properly, it may
cause color distortions. So, pay attention to the following
when installing the speakers.

– When placing the speakers near a TV set, turn off the TV’s

main power switch or unplug it before installing the
speakers.
Then wait at least 30 minutes before turning on the TV’s

main power switch again.
Some TVs may still be affected even though you have
followed the above. If this happens, move the speakers
further away from the TV.

• Tuner reception may become noisy or hissing if a speaker is
installed near the tuner. In this case, leave more distance
between the tuner and the speakers or use an outdoor
antenna for better tuner reception without interference from
the speakers.

• Do not lean against the speakers, as the speakers could fall
down or break, possibly causing an injury. Especially be
careful that children do not lean against them.

7 Precautions for daily use

• To maintain the appearance of the speakers

Wipe with a dry, soft cloth if the cabinet should become dirty.
If very dirty, apply a small amount of water or neutral
detergent to the cloth and wipe clean, then wipe with a dry
cloth.

• To improve the sound field

– It is recommended to leave a space of more than 50 cm

between the speakers and the wall.

– If the speakers are facing a solid wall or glass door, etc., it

is recommended to furnish the wall with materials that
absorb sounds, for example by hanging up thick curtains,
to prevent reflections and standing waves.

• To use the speakers without any trouble

– Do not reproduce sounds at so high a volume that they are

distorted; otherwise, the speakers may be damaged by
internal heat buildup.

– When moving the speakers, do not pull the speaker cords;

otherwise, the speakers may fall over, causing damage or
injury.

7 安裝時的注意事項

• 為了防止人員受傷或意外跌損機器，在拆開
包裝，搬運和安裝本機時需要由兩個人來完
成。

• 切勿將揚聲器放置在凹凸不平處或受到震動
處。否則揚聲器摔落可能導致自身損壞或損
傷他物。

– 在選擇安裝場所時，須事先考慮到可能會發生地震或其他物

理性衝擊等情況，確保揚聲器安裝牢靠。

• 為防止機殼變形或變色，勿將揚聲器安裝在受到陽光直射或高
度潮濕處，亦避免安裝在空調器的排氣孔附近。

• 揚聲器的振動可能產生顫噪。應盡量將揚聲器遠離唱機放置。

• 儘管揚聲器具有磁性屏蔽性能可以避免造成電視機色彩失真，

但如果安裝不當仍然可能引起電視機色彩失真。因此在安裝揚
聲器時請注意以下事項。

– 如果欲將揚聲器安裝在電視機附近，在安裝揚聲器之前請先

關閉電視機的主電源開關或拔下電源插頭。

在重新啟動電視機的主電源之前至少要等待 30 分鐘。
儘管您已經按照上述方法去做，有些電視機仍然會受到影響。
發生此種情況時，須將揚聲器移到遠離電視機處進行安裝。

• 如果將揚聲器安裝在調諧器附近，在調諧器接收時可能出現噪
音或嘶嘶聲。發生此種情況時，須將調諧器與揚聲器之間多空
出一些距離，或者使用室外天線，這樣調諧器便不會受到揚聲
器的干擾，而獲得較好的接收效果。

• 切勿倚靠在揚聲器上，因為揚聲器可能摔倒或摔壞，而且可能
砸傷人。特別注意不要讓兒童倚靠在揚聲器上。

22.0 kg / 49.0 lb.

7 日常使用時的注意事項

• 保養揚聲器的外表

如果機殼髒污，可用干爽柔軟的布進行擦拭。
如果髒污嚴重，可在布上沾少量的水或中性洗滌劑擦去污物，
然後再用干布擦拭。

• 改良音場

– 建議在揚聲器與牆壁之間留出 50 cm 以上的間隔。
– 如果揚聲器面對固質材料的牆壁或玻璃門等設施，建議您使

用吸音性材料，如厚料窗簾來裝飾牆壁，這樣便可以防止發
生反射波和駐波。

• 常規使用揚聲器

– 勿在極高，乃至出現聲音失真的音量下播放音響，否則揚聲

器內部熱量積聚可能損壞揚聲器。
在移動揚聲器時勿拉扯揚聲器導線；

–

致自身損壞或損傷他物。

否則揚聲器摔落可能導

Preparation

7 Checking the supplied accessories

• Feet (2) • Speaker grille (1)

• Screws (4)

If any item is missing, contact your dealer immediately.

7 Attaching the feet

To prevent the speaker from falling over, be sure to attach the
supplied feet to the speaker.

• Take care not to drop the feet or speaker while assembling;
otherwise, it may cause damage to the floor or injury.

• Ensure enough space for assembly and installation.

• Place a large, thick cloth on the floor where you assemble the
speaker, so you can protect the floor and the speaker itself.

• Do not touch the speaker units.

1

Turn the speaker upside down.

Connection

7 Connecting the speaker system to the amplifier

Before connection—

• Turn off the power to the amplifier before connecting the
speaker system; otherwise, the speakers may be damaged.

• The impedance of the speaker is 6 Ω. Before connecting it to
your amplifier, check the speaker impedance range of your
amplifier. If the impedance of this speaker is out of the
speaker impedance range indicated on the amplifier, you
cannot connect this system to the amplifier.

• The maximum power handling capacity of the SX-LT55MK2 is
150 W. Excessive input will result in abnormal noise and
possible damage.

• Be sure to turn down the volume level to prevent unwanted
noise before performing following operations:

– Turning on or off other components,
– Operating the amplifier,
– Tuning FM stations,
– Fast-forwarding a tape,
– Continuously reproducing high frequency oscillation or high

pitch electronic sounds.

• When using a microphone, do not aim it at the speakers or
use it near the speakers; otherwise, the howling which occurs
may damage the speakers.

• Before replacing the cartridge, always turn off the power to the
turntable; otherwise, the clicking noise may damage the
speakers.

• Use speaker cords as follows;

– Buy thick speaker cords rather than thin cords, and make

them as short as possible for connection.

– Use speaker cords of the same length for both left and right

speakers.

– Do not use long speaker cords; otherwise, the sound quality

may deteriorate.

– Using a special speaker cord such as a litz wire, a coaxial

cable, or a cord which has the specified connecting
directionality may influence the sound quality.

7 Connecting the speaker cord

Connect the “INPUT” terminal of the speaker to the speaker
terminal of the amplifier.

knob counterclockwise and fit
the speaker cord into the
groove. Then rotate the knob
clockwise to secure the cord.

• 在安裝過程中小心不要摔落支腳或揚聲器，否則可能砸傷地板或
砸傷人。

• 確保為組裝和安裝操作留置足夠的空間。

• 在欲組裝揚聲器處的地板上鋪一張大的厚布，以便保護地板和揚

聲器。

連接

7 將揚聲器系統連接到功率放大器上

進行連接之前—

• 在連接揚聲器系統之前，首先關閉功率放大器的電源，否則可
能損壞揚聲器。

• 每隻揚聲器的阻抗為 6 Ω。在將揚聲器系統連接到功率放大器上
之前，首先檢查功率放大器能夠對應的揚聲器阻抗範圍。如果
揚聲器的阻抗超出了功率放大器上標出的揚聲器阻抗範圍，便
不能將該揚聲器系統連接到功率放大器上。

• SX-LT55MK2 的最大額定功率為 150 W。超過該值以上的信號傳
入時將會產生異常噪音並可能受到損壞。

• 在執行下列操作之前確保調低音量水平，以防止出現異常噪
音：

– 啟動或關閉其他組件，
– 操作功率放大器，
– 調收 FM 電台，
– 快速前進倒帶，
– 連續播放高頻振幅或高調電子音。

• 在使用麥克風時，不要將其朝向揚聲器，也不要在揚聲器附近
使用，否則顫噪可能會損壞揚聲器。

• 在更換唱頭之前，請務必關閉唱機的電源，否則喀噪音可能會
損壞揚聲器。

• 請按如下規定使用揚聲器導線；
– 購買揚聲器導線時盡量買粗的而不要買細的，而且接線盡量

要短。

– 對左置和右置揚聲器使用相同長度的揚聲器導線。
– 不要使用過長的揚聲器導線，否則音響質量會降低。
– 使用特殊的揚聲器導線，如辮線，同軸電纜或帶有特定的連

接定向性的導線可能會影響音響質量。

7 連接揚聲器導線
