Warnings, Cautions and Others

7 Precautions for installation

• Do not install the speakers on an uneven surface or in a place
subject to vibration; otherwise, they may fall over, causing
damage or injury.
– Take the occurrence of earthquakes or other

physical shocks into consideration when
selecting the installation place, and secure the
speakers thoroughly.

• To prevent deformation or discoloration of the
cabinet, do not install the speakers where they are
exposed to direct sunlight or high humidity, and
avoid installation near air conditioning outlets.

• Speaker vibrations may cause howling. Place the
speakers as far away from the player as possible.

• The speakers are magnetically shielded to avoid
color distortions on TVs. However, if not installed
properly, it may cause color distortions. So, pay attention to the
following when installing the speakers.
– When placing the speakers near a TV set, turn off the TV’s

main power switch or unplug it before installing the
speakers.
Then wait at least 30 minutes before turning on the TV’s

main power switch again.
Some TVs may still be affected even though you have followed
the above. If this happens, move the speakers further away
from the TV.

• Tuner reception may become noisy or hissing if a speaker is
installed near the tuner. In this case, leave more distance
between the tuner and the speakers or use an outdoor
antenna for better tuner reception without interference from
the speakers.

7 Checking the supplied accessories

• Speaker cord (3m, 1)

• Feet (4)

If any item is missing, contact your dealer immediately.

7 Attaching the feet

Attach the supplied feet on the bottom of the speaker, so that you
can protect the speaker cabinet, decrease the vibration of the
speaker cabinet and prevent the speaker from slipping.

• Turn the speaker upside down and attach the feet as
illustrated.

7 Precautions for daily use

• To maintain the appearance of the speakers

Wipe with a dry, soft cloth if the cabinet should become dirty.
If very dirty, apply a small amount of water or neutral detergent
to the cloth and wipe clean, then wipe with a dry cloth.

• To improve the sound field

– It is recommended to leave a space of more than 50 cm

between the speakers and the wall.

– If the speakers are facing a solid wall or glass

door, etc., it is recommended to furnish the wall
with materials that absorb sounds, for example by
hanging up thick curtains, to prevent reflections
and standing waves.

• To use the speakers without any trouble

– Do not reproduce sounds at so high a volume that they are

distorted; otherwise, the speakers may be damaged by
internal heat buildup.

– When moving the speakers, do not pull the speaker cords;

otherwise, the speakers may fall over, causing damage or
injury.

Place a large, thick cloth under the speaker in order to
protect the floor and the speaker.

7 To remove the speaker grille

To remove the speaker grille, insert your fingers at the bottom
of the speaker grille, then pull upward.

To attach the speaker grille, put the projections of the speaker
into the holes of the speaker grille.

• Do not push the speaker grille strongly.

Connection

7 Connecting the speaker system to the amplifier

Before connection—

• Turn off the power to the amplifier before connecting the
speaker system; otherwise, the speakers may be damaged.

• The impedance of the speaker is 6 Ω. Before connecting it to
your amplifier, check the speaker impedance range of your
amplifier. If the impedance of this speaker is out of the speaker
impedance range indicated on the amplifier, you cannot
connect this system to the amplifier.

• The maximum power handling capacity of the SX-LC33 is
120 W. Excessive input will result in abnormal noise and
possible damage.

• Be sure to turn down the volume level to prevent unwanted
noise before performing following operations:
– Turning on or off other components,
– Operating the amplifier,
– Tuning FM stations,
– Fast-forwarding a tape,
– Continuously reproducing high frequency oscillation or high

pitch electronic sounds.

• When using a microphone, do not aim it at the speakers or
use it near the speakers; otherwise, the howling which occurs
may damage the speakers.

• Before replacing the cartridge, always turn off the power to the
turntable; otherwise, the clicking noise may damage the
speakers.

7 Connecting the speaker cord to the speaker

Connect the speaker cord to the speaker as follows.

1

Twist and remove the insulation at the end of each
speaker cord before connecting.

2

Rotate the speaker terminal knob counterclockwise and
fit the speaker cord into the groove. Then rotate the knob
clockwise to secure the cord.

About speaker cords—to improve the sound quality

About the OFC cord

The core wires of the supplied speaker cords are made of OFC (Oxygen Free Copper). This OFC cord enables high quality
sound reproduction.

When connecting the speaker cords

Make sure to match the polarity (ª and ·); otherwise, the surround effect will become less effective.
After connecting, check that the exposed cores are fully inserted into the terminal.

When using other speaker cords

Observe the following;

• Buy thick speaker cords rather than thin cords, and make them as short as possible for connection.

• Do not use long speaker cords; otherwise, the sound quality may deteriorate.

• Use speaker cords of the same length for both left and right speakers.

• Using a special speaker cord such as a litz wire, a coaxial cable, or a cord which has the specified connecting directionality

may influence the sound quality.
