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.

Red cord side

Center 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.

En2

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 cork spacers or thin metal discs (such as coins) to seat the speaker stably.

D-407C Center Speaker

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:

• The supporting area of the TV is larger than that of the D-

407C.

• The TV's support surface is flat and level.

• The TV is not placed on an unstable support.

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 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.

3. To replace the grill, push the projections at the corners into the grille plug holes on the speaker cabinet.

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.

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.
