Speaker Precautions
Placement
• The subwoofer cabinet is made out of wood
and is therefore sensitive to extreme tem-
peratures and humidity, do not put it in loca-
tions subject to direct sunlight or in humid
places, such as near an air conditioner,
humidifier, bathroom, or kitchen.
• Do not put water or other liquids close to the
speakers. If liquid is spilled over the speak-
ers, the drive units may be damaged.
• Speakers should only be placed on sturdy,
flat surfaces that are free from vibration.
Putting them on uneven or unstable sur-
faces, where they may fall and cause dam-
age, will affect the sound quality.
• Subwoofer is designed to be used in the
upright vertical position only. Do not use it
in the horizontal or tilted position.
• If the unit is used near a turntable, CD
player or DVD player, howling or slipping
of sound may occur. To prevent this, move
the unit away from the turntable, CD player
or DVD player, otherwise lower the unit’s
output level.
Using Close to a TV or Computer
TVs and computer monitors are magnetically
sensitive devices and as such are likely to suf-
fer discoloration or picture distortion when
conventional speakers are placed nearby. To
prevent this, the HTX-22HDST features
internal magnetic shielding. In some situa-
tions, however, discoloration may still be an
issue, in which case you should turn off your
TV or monitor, wait 15 to 30 minutes, and
then turn it back on again. This normally acti-
vates the degaussing function, which neutral-
izes the magnetic field, thereby removing any
discoloration effects. If discoloration prob-
lems persist, try moving the speakers away
from your TV or monitor. Note that discolor-
ation can also be caused by a magnet or
demagnetizing tool that’s too close to your
TV or monitor.
Input Signal Warning
The speakers can handle the specified input
power when used for normal music reproduc-
tion. If any of the following signals are fed to
them, even if the input power is within the
specified rating, excessive current may flow
in the speaker coils, causing burning or wire
breakage:
1.
Interstation noise from an untuned FM
radio.
2.
Sound from fast-forwarding a cassette
tape.
3.
High-pitched sounds generated by an
oscillator, electronic musical instrument,
and so on.
4.
Amplifier oscillation.
5.
Special test tones from audio test CDs
and so on.
6.
Thumps and clicks caused by connecting
or disconnecting audio cables (Always
turn off your amplifier before connecting
or disconnecting cables.)
7.
Microphone feedback.
