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.
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.
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 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.
