Caring for Your Speakers
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-320F and SKC-320C
speakers feature internal magnetic shielding. In some
situations, 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
neutralizes the magnetic field, thereby removing any dis-
coloration 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 SKM-320S close to TV or a computer mon-
itor because it has no magnetic shield.
Operating Precautions
The HTP-320 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.
Speaker Care
Wipe the cabinet occasionally with a dry silica or soft
cloth. For heavier dirt, after dampening a soft cloth in a
weak solution of mild detergent and water and wringing it
out dry, wipe off the dirt. Then, dry immediately with a
clean cloth. Do not use rough material, thinners, alcohol or
other chemical solvents or cloths since these could damage
the finish, remove the panel lettering, or cause discolora-
tion. If you are using a chemical cloth, always follow the
instructions that come with the cloth. For dust accumulated
on grilles, use a vacuum cleaner or brush it off.
Troubleshooting
Symptom Possible cause Remedy
There’s no sound coming
from certain speakers?
The speaker cables are not connected properly. Check the speaker cables and correct as necessary.
The number of speaker channels is not set to 5ch
on the HT-R320.
Set the number of speaker channels to 5ch.
The subwoofer does not
turn on?
The power plug is not fully inserted into the wall
outlet.
Insert the power plug fully into the wall outlet.
The subwoofer produces
no sound?
The OUTPUT LEVEL control is set to minimum. Turn up the OUTPUT LEVEL control.
The RCA cable is not properly connected to the
subwoofer’s LINE INPUT.
Make sure that the RCA cable is properly connected to
the subwoofer’s LINE INPUT.
The level of the input signal was too low and the
subwoofer entered Standby mode.
Slightly increase the subwoofer preout output level on
your amp.
On the HT-R320 Receiver, the subwoofer mode is
set to SW Off.
Set the subwoofer mode to something other than SW
Off.
The subwoofer produces
hardly any sound?
The source material contain little or no bass con-
tent.
Choose source material with more bass content.
A humming sound can be
heard from the sub-
woofer?
The RCA cable is not properly connected to the
subwoofer’s LINE INPUT.
Make sure that the RCA cable is properly connected to
the subwoofer’s LINE INPUT.
External interference from a TV or other elec-
tronic device is being picked up.
Move the subwoofer and RCA cable away from the interfer-
ence source. Make sure your audio system is grounded properly.
