the supplied feet to the speaker.

· Take care not to drop the feet or speaker while assembling;

otherwise, it may cause damage to the floor or injury.

· Ensure enough space for assembly and installation.

· Place a large, thick cloth on the floor where you assemble the

speaker, so you can protect the floor and the speaker itself.

Warnings, Cautions and Others

7 Precautions for installation

· To avoid personal injury or accidentally

dropping the unit, have two persons unpack,

carry, and install the unit.

· 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.

· Do not lean against the speakers, as the speakers could fall

down or break, possibly causing an injury. Especially be

careful that children do not lean against them.

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.

7 Conventional connection

1 Loosen the knobs of the "FULL RANGE" terminals.

2 Fit the speaker cords into the grooves of the "FULL

RANGE" terminals, then tighten the knobs to secure the

speaker cords and short-circuit plates.

7 Bi-wiring connection

This speaker is bi-wireable. Comparing with the conventional

connection, the bi-wiring connection makes the sound field

larger, deeper, and richer.

1 Loosen all speaker terminal knobs and detach the

short-circuit plates.

2 Connect the "FULL RANGE" terminals and "LOW

FREQUENCY" terminals separately to the speaker

terminals of the amplifier.

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

. 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-LT55 is

150 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.

· Use speaker cords as follows;

Buy thick speaker cords rather than thin cords, and make

them as short as possible for connection.

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

speakers.

Do not use long speaker cords; otherwise, the sound quality

may deteriorate.

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.

7 Connecting the speaker cord

Connect the "INPUT" terminal of the speaker to the speaker

terminal of the amplifier.

Rotate the speaker terminal

knob counterclockwise and fit

the speaker cord into the

groove. Then rotate the knob

clockwise to secure the cord.

· Make sure to match the polarity (

ª and ·); otherwise, the

surround effect will become less effective.
