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.

Connection

• 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 6

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 below.

• 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.

Connecting to AV amplifier

1. Strip off the end of plastic skin, and give a twist to the core wire.

2. Slacken the screw and thread the core wire deep enough into the hole.

3. Hold the core wire tight by fastening the screw in the direction of an arrow.

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.

Speaker terminals of the 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 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.

Caution:

• Allow for secure placement of the speaker; the cabinet is very tall and tends to fall down under unstable conditions.

Do not place it on an unstable location such as shaky or sloping table, platform or thick carpet. Otherwise it could cause injury when dropping or falling.

• You can secure the cabinet to the wall, etc. by using a durable cord or chain along with cup hooks: Find a hole on the either side of backside the cabinet, and screw into each hole the cup hook of about 4mm in diameter and

15mm long, and then secure the cabinet to the wall, etc.

with the cord or chain.

Secure the cabinet to the wall, etc.

• Exercise due care to install and secure the cabinet; the sustainability of the screws may vary depending on the quality and/or location of the wall where they are tightened.

You may want to consult with a professional installer.

Placement

D-407F 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 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 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.

Removal Replacement

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 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.

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.

安放

D-407F 前置揚聲器

安裝揚聲器系統的房間的結構、面積，以及家具的擺放位置和

尺寸都將對揚聲器系統再生音響的音質有顯著的影響。為了獲

得最佳的音質，請遵守下列注意事項。

•請勿將揚聲器系統安放在凸出的物體如水泥磚上。相反，

應將其安放在振動最小的牢固平面上。注意，如果揚聲器

系統安放不穩，將不能得到高質量的低音。一般而言，與

直接安放在平面上相比，將揚聲器系統安放在幾個支腳上

能獲得更佳的低音效果。另外，如果您感到系統再生的低

音太弱，請移動揚聲器系統，使其離後面的牆壁更近。這

樣，您就可以通過調節揚聲器的位置來控制再生低音的強

弱。

•很多房間，其家具和牆壁會影響再生音響的音質。再生立

體聲音響時，使左側和右側的揚聲器安放在同樣狀態下將

帶來最佳的效果。如果牠們安放的狀態截然不同，則將對

左聲道和右聲道的平衡帶來不良影響。

•揚聲器系統理想的安放位置是：想像一個等邊三角形，將

左側和右側的揚聲器分別安放在底邊的兩端，理想的欣賞

位置就在三角形的頂點或稍微靠後一點的地方。

•處在揚聲器系統前方的光滑的門或牆壁可能會因聲音的反

射而導致某些音響頻段的共鳴。為了消除共鳴，可在門或

牆壁前放置一些吸音材料，如厚窗簾等。

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。

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。

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。

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。

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。
