Placement

Precaution on use

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.

Placing the speaker system directly onto the floor surface results in undesirable boom, that is, sound with extremely heavy bass. Place each speaker on a speaker stand, concrete blocks, bricks or rigid bookshelf.

High-quality bass sound cannot be obtained if the speak- ers are not seated stably on a speaker stand or other base. Insert thin discs of cork or metal (such as coins) to seat the speakers stably.

Thin discs of metal, such as coins

If speakers are placed on a bookshelf etc., where a large area of the speaker surface makes contact with the supporting surface, reducing the contact area between the speakers and the bookshelf by inserting cork discs or coins generally improves the sound quality.

To obtain a deeper bass sound, mount the speakers on lower speaker stands and place them in front of a wall with sufficient rigidity.

In many rooms, the furniture and wall affect the repro- duced sound quality. For stereo sound reproduction, plac- ing 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 reso- nance, place some sound-absorbing material such as a thick curtain in front of the doors or walls.

Use with a TV set or computer

In general, Braun tubes used for color television sets and computers 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 a color television set or computer, 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 or computer, wait for 15 to 30 minutes and then turn it on again. This activates the self-demagnetizing func- tion of the television set or computer, improving the display condition. If discoloration persists even after performing this remedy, move the speaker apart from the television set or computer. Discoloration may also be caused when a magnet or other magnetizing object exists near the television or computer because of the combined effect.

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, how- ever, 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 au- dio 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 care

Wipe the cabinet occasionally with a dry silica or soft cloth. For heavier dirt, after dampening a soft cloth in a weak solution of mild detergent and water and wringing it out dry, wipe off the dirt. Then, dry immediately with a clean cloth. Do not use rough material, thinners, alcohol or other chemical solvents or cloths since these could damage the finish or cause discolora- tion. If you are using a chemical cloth, always follow the instructions that come with the cloth. For dust accumulated on grilles, use a vacuum cleaner or brush it off.
