Placement
Attaching and detaching the speaker grilles
For better-quality sound, observe the following precautions
when you install the speaker system:
This speaker system uses detachable grilles. Use the
following method to attach or detach the grilles.
• 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.
1. While holding the left (or right) side 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 right (or left) side edge of
the speaker grille toward you to remove it from the main
unit.
D-407C Center Speaker
3. To replace the grill, push the projections at the corners into
the grille plug holes on the speaker cabinet.
Place the D-407C as close as possible to your television set,
for example, above or below the television set. Be sure to set
the D-407C 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 D-407C is to be placed on a
television set, be sure that:
2
• The supporting area of the TV is larger than that of the D-
407C.
To detach the speaker
1
• The TV's support surface is flat and level.
• The TV is not placed on an unstable support.
grille, pull it gently at the left
and right side edge.
D-407C
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.
Attach the circular cork pieces as slip stopper onto the bottom
surface of the speaker. And you can secure the cabinet to the
wall, etc. by using a durable cord with cup hooks: Find a hole
on the either side of backside the speaker, and screw into
each hole the cup hook of about 4 mm in diameter and 15 mm
long, and then secure the speaker to the wall, etc. with the
cord. Place the speaker with the sloping side up, unlike in the
case when placed in lower location.

Speaker care
Your Onkyo speakers are finished with a high quality 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.
Secure the
cabinet to
the wall, etc.

Durable cord
Natural wood finished cabinets
The cabinets are finished with a natural wood surface. They
have a unique wood grain pattern. Your cabinets have their
own raw beauty and uniqueness which is unlocked from the
tree; this is depicted by the cross-grain patterns with dark and
light coloring. You can enjoy Onkyo’s craftsmanship not only
when designing for the best sound quality, but to assimilate
natural blessings for the visual senses. The paint and finishing
work of the cabinets are conducted under the strictest quality
control standards.

使用本系統之前
連接
‧本揚聲器的箱體是木質的，因此，對極高(或極低)的溫度
和溼度非常敏感。請不要將揚聲器系統放置在陽光直射之
處，或多煙塵和高濕氣的地方，如靠近空調機、加濕器或
浴室、廚房中。否則，將會損壞揚聲器。
‧在連接揚聲器纜線之前，請先將AV接收器音量調至最小，
並關閉AV接收機電源開關(POWER)。
‧本揚聲器系統的額定阻抗是6Ω。請只使用對應於此阻抗的
AV接收機。
‧請將系統放置在牢固的水平表面上。若將其放置在斜面上
或放置不穩，則不僅會有揚聲器系統跌落的危險，還會降
低其音質。
‧如下圖所示，使用隨機附帶的揚聲器纜線，連接揚聲器的
接線柱和AV接收機的揚聲器端子。
‧連接揚聲器纜線時，請正確地纏繞芯線，將其牢固地連接
在端子上。這時，請確認芯線沒有相互接觸。請注意，芯
線間的短路會導致AV接收機的損壞。
‧在連接揚聲器系統之前，請務必先關閉您的AV接收機。若
在AV接收機電源打開的狀況下進行連接，則可能會損壞AV
接收機或揚聲器系統。
‧請注意不要讓水或其它液體濺入本系統。如果有水濺入本
系統，本系統和揚聲器都有可能受到損壞。
連接到AV接收機
1.將末端的絕緣塑
膠層脫去，將線
心扭緊。
2.放鬆螺釘並將線心 3.藉著將螺釘依照箭

深度。
頭的方向鎖緊，讓

使用注意事項
‧當本揚聲器系統被用來進行普通的音樂再生時，可以承受
一定的輸入功率。但如果下述異常信號被輸入揚聲器，即
使其輸入功率低於最大輸入功率，也有可能在內部電路中
產生過大的電流，使線路燒毀或損壞。

1.當收聽調頻廣播未調准電台時產生的噪音
2.當盒式錄音帶快進時產生的聲音
3.由振蕩器、電聲樂器等產生的高頻音響
4.振蕩的AV接收機信號
5.由音頻測試CD等產生的特殊測試信號
6.在連接或拆除音頻纜線時產生的聲音(請務必在連接或
拆除纜線前關閉AV接收機的電源)。

7.使用麥克風時的反饋嘯聲
接收機的中央揚聲器端子
‧請勿將螺絲刀等磁性物體和鐵制物品放置在揚聲器系統附
近，因為牠們會通過強磁場影響揚聲器系統，或者，牠們可
能會被磁性吸至揚聲器上，導致振動膜的損傷或徹底損壞。
在打開AV接收機的電源開關之前：
‧確認揚聲器纜線的正極(+)和負極(-)沒有相互接觸。否則
可能會發生短路，導致AV接收機的損壞。
‧在連接揚聲器纜線時，一定要保證極性的正確。(將揚聲器
的正(+)和負(-)接線柱連接至AV接收機上相應的揚聲器端
子。) 極性接反將會妨害低音的再生，併導致聲場不能正
確定位。同時，請務必使左側和右側的兩個揚聲器與AV接
收機上相應的揚聲器端子正確地連接。
‧輕拉揚聲器纜線，以確認其已牢固地連接。

安放
揚聲器前格板的安裝和拆除
為了獲得最佳的音質，在安裝揚聲器系統時請遵守下列注意事
項：
本揚聲器系統使用可拆式前格板。安裝和拆除的方法如下。
1.用兩手抓住揚聲器前格板的左(或右)邊，輕輕向外拉，將
前格板的下部拆開。
‧般而言，與直接安放在平坦表面上相比，將揚聲器系統安
放在幾個支腳上能獲得更佳的音質。另外請注意，如果揚
聲器系統安放不穩，將不能得到高質量的低音。請使用隨
機軟木間隔墊或薄金屬片(如硬幣)將揚聲器墊穩。
2.用同樣的方法，輕輕向外拉前格板的右(或左)邊，將前格
板從箱體上拆下。
3.安裝前格板時，將突起部推入揚聲器箱體的前格板安裝插
孔。
D-407C 中央揚聲器
安放D-407C揚聲器時，應盡可能將其靠近您的電視機，例如，
放在電視機之上或電視機之下。安放在電視機或其它部件之上
時，請確保D-407C安放穩固，不會滑動或跌落。這在您家中有
小孩時尤其重要。如果您要將D-407C安放在電視机上，請務必
保證:
2
‧電視機支持面的面積要比D-407C的底面積大。
‧電視機的支持面必須為水平的。
‧電視機被穩固地安放。
欲分離揚聲器前格板時，
請從板子的左、右邊緣輕
輕地拉開。

作為電視機的外接揚聲器使用時
通常，應用於彩色電視機等的陰極射線管是極為敏感的，牠們
甚至會受到地球磁場的影響。如果揚聲器系統靠近牠們，則會
產生色調混亂或圖像失真。為了能夠和彩色電視機等同時使
用，本揚聲器系統進行了磁場屏蔽，將磁場限制於箱體內。
將圓形的軟木塞片當作阻滑片連接至揚聲器的底面。您可以使
用帶有杯掛鉤的堅固繩索將櫃子固定於牆上及其他東西之上：
在揚聲器背面的任一側找出一個孔，將直徑約 4 mm，長約 15
mm的杯掛鉤鎖入每一個孔內，然後使用繩索將揚聲器固定至牆
壁或其他東西之上。安置揚聲器使其傾斜面向上（不同於將其
安置於較低位置時的擺放方式）
但是，即使進行了屏蔽，根據安裝的環境，也有可能發生色調
混亂。如果出現色調混亂，請關閉電視機的電源，等待15至30
分鐘，然後再次打開電視機電源。這將啟動電視機的自動消磁
功能，改善顯示狀況。如果在進行這種補救措施後仍有色調混
亂，請將揚聲器離開電視機遠一些。由於綜合影響，當一塊磁
鐵或其它磁性物體放置在電視機附近時，也有可能出現色調混
亂現象。

長約 15 mm的杯掛鉤
揚聲器的維護保養
您的Onkyo揚聲器表面覆蓋了高質量的膜，以保護木質的箱
體。
請定期用一塊硅夾層軟布或普通軟布擦拭機體。
將揚聲器固
其表面可以用軟布蘸清水來擦拭，可以使用刺激性不強的肥
皂。請不要使用家具拋光劑或去污粉。
圓形軟木塞片
堅固的繩索
定至牆壁或
其他東西之
上
請用軟刷或手持型吸塵器去除沾在前格板上的灰塵和絨毛。
天然原木表面的櫃子
本櫃子的表面係使用天然原木作成的。這種表面有特殊的木質
晶格的花樣。讓您的櫃子富有樹木所具有的原始美麗的色澤和
特色；這些特點則藉著其深淺顏色的交叉晶格的花樣表現出
來。您不但可以享受 Onkyo 所設計出的最優良的音質，也帶
給您融入大自然造化的視覺享受。櫃子的油漆和表面處理是在
嚴格的品質控制之下進行的。
