Owner's Manual

Placement
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. � It is recommended not to place the speakers on blocks, but place the speakers on a sturdy floor or surface that does not transmit vibrations. It is especially important to refrain from placing the speakers on shag carpeting for the speakers may tip over and the sound quality will be adversely affected. Moreover, high-quality bass sound cannot be obtained if the speakers are not seated stably on the floor. Insert coins or other thin discs to seat the speakers stably. As a general rule, having the speakers resting on a number of points provides better sound than having it rest completely on one surface. If the bass sounds are low, place the speakers close to the wall behind it to prevent the bass sounds from escaping. You can then obtain the desired bass level by adjusting how far from the wall the speakers are placed. 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. A base extension is provided with the speakers to prevent the speakers from being tipped over (base extension: 260 mm (10-1/4") length, M4 x 35 mm (1-3/8") screws). To install the base extension, align it with the holes located on the rear of the speaker stand and secure it with the screws provided.

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 selfdemagnetizing function 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. Note: When you use speakers near a television set or computer, a noise generated by TV�s electromagnetic wave may come out from the speakers even after the power of amplifier is turned off. If you want to avoid this noise, place speakers apart more from a television set or computer.

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.
