Speaker Precautions
Placement
• The subwoofer cabinet is made out of wood and is
therefore sensitive to extreme temperatures and
humidity, do not put it in locations subject to direct
sunlight or in humid places, such as near an air condi-
tioner, humidifier, bathroom, or kitchen.
• Do not put water or other liquids close to the speakers.
If liquid is spilled over the speakers, 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 surfaces, where they may fall and cause dam-
age, will affect the sound quality.
• Subwoofer is designed to be used in the upright verti-
cal position only. Do not use it in the horizontal or
tilted position.
• If the unit is used near a turntable, CD player or DVD/
BD player, howling or slipping of sound may occur.
To prevent this, move the unit away from the turntable,
CD player or DVD/BD 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 suffer discoloration or
picture distortion when conventional speakers are placed
nearby. In such situations, try moving the speakers away
from your TV or monitor. If discoloration should occur,
turn off your TV or monitor, wait 15 to 30 minutes, and
then turn it back on again. This normally activates the
degaussing function, which neutralizes the magnetic
field, thereby removing any discoloration effects. Note
that discoloration can also be caused by a magnet or
demagnetizing tool that’s too close to your TV or moni-
tor.
Input Signal Warning
The speakers can handle the specified input power when
used for normal music reproduction. 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 discon-
necting audio cables (always turn off your amplifier
before connecting or disconnecting cables).
7. Microphone feedback.
