Speaker Precautions

Placement
• The speaker cabinets are made out of wood and are
therefore sensitive to extreme temperatures and
humidity, do not put them 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 or CD player, howl-
ing or slipping of sound may occur. To prevent this,
move the unit away from the turntable or CD 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. To prevent this, the SKF-820F and SKC-
820C feature 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 activates the degaussing function, which neu-
tralizes the magnetic field, thereby removing any discol-
oration effects. If discoloration problems persist, try
moving the speakers away from your TV or monitor.
Note that discoloration can also be caused by a magnet
or demagnetizing tool that's too close to your TV or
monitor.
Do not place surround speakers close to TV or a com-
puter monitor because they have no magnetic shield.
Input Signal Warning
The speakers can handle the specified input power when
used for normal music reproduction. If any of the fol-
lowing 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.
