Placement, Use with a TV set, Speaker care

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.

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.
