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.

Precautions for Daily Use
• To maintain the appearance of the speakers
Wipe with a dry, soft cloth if the cabinet or control panel 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.
Speaker and Speaker cords—to improve the sound quality
About DD (Direct Drive) speaker
DD (Direct Drive) technology improves sound localization and transmits the powerful sounds.
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.
• 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.

M4 x 25 mm (M4 x 1 in.) (15)
• Washers (5)
If any of the items above are missing, contact your dealer immediately.
• To improve the sound field
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.
– When holding a satellite speaker, do not
grasp the speaker (upper) portion, but
always grasp the leg (lower) portion of the
satellite speaker.

Connecting the speaker system to the amplifier
Before connecting—
• Turn off the power to the amplifier before connecting the speaker
system; otherwise, the speakers may be damaged.
• The impedance of each speaker is 6 Ω. Before connecting them
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-XD55 is 100 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.

Typical connection method to an amplifier
Connect the speakers to a speaker terminal of the amplifier with the
speaker cords by referring to the diagram on the left.
• Make sure to match the polarity (
ª and ·) when connecting the
speaker cords.

General layout of speakers
Place all speakers at the same distance from the listening
position if possible.
• Usually place the center speaker close to the TV.
• When you place the center speaker on a TV, make sure the
surface is level and stable.
* For a subwoofer, JVC’s SP-DWF10 is recommended. This
combination gives you the best possible high-quality surround
sounds.
