We recommend saving the cushioning and other packing materials, even
after unpacking the product from the carton box. Harman International
Japan will not be responsible for damage caused by improper packaging
when using materials other than those of the original carton box when
transporting the units for moving, repairs, or other reasons.
PLaCEMEnT
Please refrain from placing speakers near amplifiers, which produce a
large amount of heat, in areas with high amounts of humidity or dust, or in
areas exposed to direct sunlight. Place the speakers on hard, stable floor
surfaces or on stands.
*While this speaker system is magnetically shielded to limit its magnetic
effect on television screens, when the speakers are placed near a
television, colors on the screen may become distorted depending on
the construction and type of television. Also, the internal circuit elements
may react to the high frequency magnetism radiating from the television,
resulting in noise or distortion. If this occurs, please place the speakers
slightly further away from the television.
*Speaker systems are durable consumer goods. Their lifespan can be
shortened due to effects from temperature, humidity, ultraviolet light,
etc. Please keep the speakers away from bright light fixtures and direct
sunlight, and from places with high temperatures, such as near the
exhaust outlets of air conditioners or heaters. Also, please refrain from
placing the speaker system in closed automobiles or next to windows with
direct sunlight.

• The proper placement method for this speaker system is for the high
frequency tweeter unit with the mesh grille to be placed on the outward
side. In order to get the best stereo effect, please place the left and
right speakers at an equal distance to the left and right in front of the
listener. While the sound field will become wider as more space is placed
between the left and right speakers, the stereo-image quality of center-
oriented elements such as vocals will weaken. Please adjust the space
between the speakers to match the distance with the listening position.
• The sound localization for these speakers is the center of the treble unit,
and placing your ears at a listening position at this height will provide the
best sound localization and sound field. Please adjust the height of the
system using commercially available speaker stands and racks.
• The environment in which speakers are placed generally has a strong
influence on the sound quality of low frequencies. If you place the
speakers in corners of your room, lower frequencies will be enhanced,
and while this will allow you to savor a rich, deep bass, it will also be a
dull sound with no edge. On the other hand, when placed away from the
wall, the sound will be sharp and clean, even though you sacrifice some
of the heavy bass. We recommend that you make the final decision on
the placement of the speaker system while actually playing some of your
favorite music

CAUTION: When connecting speakers to an amplifier, please do so after
turning the amplifier off. If you connect the speakers while the power is still
on, it could damage the amplifier and speakers.
This speaker system uses color-coded speaker terminals, with red for +
and black for −. Connect commercially available speaker cables to the
terminals in back while paying attention to the polarity.
*When using loose end cables on which the protective shield has been
peeled back, please be careful that the metal parts of the terminal do
not bite into the protective shield. This could interrupt sound due to poor
connection.
Also, since there is the possibility of a short circuit if the leads of the cables
touch, please do not peel back too far on the protective shield.
LEVEL aDJusTMEnT
The speaker system is equipped to allow users to adjust the levels for mid
and high frequencies, which are easily influenced by factors such as the
size and construction of the room. Adjust to the desired tone using the
control knobs at the top of the front baffle of the speakers while listening
to music with which you are familiar. The "HIGH FRQ.LEVEL" knob on the
right adjusts the high frequency tweeter, and the "MID FRQ.LEVEL" knob
on the left adjusts the midlevel frequency of the midrange unit. The levels
of the respective frequencies increase when turning the knobs clockwise
(right), and decrease when turning them counter clockwise (left). The
center position is the standard position for a normal listening environment.
*The relationship between the volume level on the amplifier and
the amount of sound from the speakers can differ depending on
the characteristics of the equipment, such as the efficiency and
impedance of the speakers, output characteristics of the amplifier
and the output level of the source equipment (such as a CD player),
as well as the combination of these. When using this speaker system
in combination with an amplifier that has low output, if the bass is
enhanced and the volume is raised to an excessive level using the
tone control or other method, clipping will occur due to distortion in
the amplifier output, and this could damage the speakers even if the
power is below the maximum recommended amplifier input. If you
sense any abnormalities in sound, please lower the volume.
MaInTEnanCE
When the speaker set becomes dirty, wipe with a soft, dry cloth.
Never use liquids that contain volatile solvents such as paint thinner
or benzene to clean the system. Also, please be careful not to apply
any spray pesticides.
If the grille net becomes dusty, remove the dust using a vacuum
cleaner. When doing so, please adjust the power on the vacuum
cleaner so the suction is not too strong. Also, do not wash the grille
with water. This may cause discoloration and sagging of the grille
to occur.
