6. Attachments – Do not use attachments not recom-
mended by the appliance manufacturer as they may
cause hazards.
7. Water and Moisture – Do not use the appliance near
water –for example, near a bath tub, wash bowl,
kitchen sink, or laundry tub; in a wet basement; or
near a swimming pool; and the like.
8. Accessories – Do not place the appliance on an
unstable cart, stand, tripod, bracket, or table. The
appliance may fall, causing serious injury to a child
or adult, and serious damage to the appliance. Use
only with a cart, stand, tripod, bracket, or table rec-
ommended by the manufacturer, or sold with the
appliance. Any mounting of the appliance should
follow the manufacturer’s instructions, and should
use a mounting accessory recommended by the
manufacturer.
9. An appliance and cart com-
bination should be moved
with care. Quick stops,
excessive force, and uneven
surfaces may cause the
appliance and cart combina-
tion to overturn.
10. Ventilation – Slots and openings in the cabinet are
provided for ventilation and to ensure reliable oper-
ation of the appliance and to protect it from over-
heating, and these openings must not be blocked or
covered. The openings should never be blocked by
placing the appliance on a bed, sofa, rug, or other
similar surface. The appliance should not be placed
in a built-in installation such as a bookcase or rack
unless proper ventilation is provided. There should
be free space of at least 20 cm (8 in.) and an open-
ing behind the appliance.
11. Power Sources – The appliance should be operated
only from the type of power source indicated on the
marking label. If you are not sure of the type of
power supply to your home, consult your appliance
dealer or local power company.
12. Grounding or Polarization – The appliance may
be equipped with a polarized alternating current line
plug (a plug having one blade wider than the other).
This plug will fit into the power outlet only one way.
This is a safety feature. If you are unable to insert
the plug fully into the outlet, try reversing the plug.
If the plug should still fail to fit, contact your elec-
trician to replace your obsolete outlet. Do not defeat
the safety purpose of the polarized plug.
13. Power-Cord Protection – Power-supply cords
should be routed so that they are not likely to be
walked on or pinched by items placed upon or
against them, paying particular attention to cords at
plugs, convenience receptacles, and the point where
they exit from the appliance.
14. Lightning – For added protection for the appliance
during a lightning storm, or when it is left unat-
tended and unused for long periods of time, unplug
it from the wall outlet and disconnect the antenna or
cable system. This will prevent damage to the appli-
ance due to lightning and power-line surges.
15. Overloading – Do not overload wall outlets, exten-
sion cords, or integral convenience receptacles as
this can result in a risk of fire or electric shock.
16. Object and Liquid Entry – Never push objects of
any kind into the appliance through openings as
they may touch dangerous voltage points or short-
out parts that could result in a fire or electric shock.
Never spill liquid of any kind on the appliance.

Precautions
1. AC Fuse
The fuse is located inside the chassis and is not userser-
viceable. If power does not come on, contact your Onkyo
authorized service station.
2. Care
From time to time you should wipe off the front and rear
panels and the cabinet with a soft cloth. For heavier dirt,
dampen a soft cloth in a weak solution of mild detergent
and water, wring it out dry, and wipe off the dirt. Follow-
ing this, dry immediately with a clean cloth. Do not use
rough material, thinners, alcohol or other chemical sol-
vents or cloths since these may damage the finish or
remove the panel lettering.
Use a vacuum cleaner to remove dust from hard-to-reach
grilles.

About Home Theater
The HTP-320’s great sound means that you can enjoy surround sound with a real sense of movement in your own
home—just like being in a movie theater or concert hall.
Enjoying Home Theater
1/3 1/3 1/3
Front left and right speakers
These output the overall sound.Their role in a home theater
is to provide a solid anchor for the sound image.They should
be positioned facing the listener at about ear level, and equi-
distant from the TV. Angle them inward so as to create a
triangle, with the listener at the apex.
Center speaker
This speaker enhances the front left and right
speakers, making sound movements distinct
and providing a full sound image. In movies it’s
used mainly for dialog.
Position it close to your TV facing forward at
about ear level, or at the same height
as the front left and right speakers.
Put it somewhere where
it won’t slide around or fall.
Subwoofer
The subwoofer handles the bass
sounds of the LFE (Low-Fre-
quency Effects) channel. The vol-
ume and quality of the bass output
from your subwoofer will depend
on its position, the shape of your
listening room, and your listening
position. In general, a good bass
sound can be obtained by install-
ing the subwoofer in a front cor-
ner, or at one-third the width of the
wall, as shown.
Surround left and right speakers
These speakers are used for precise sound positioning and to
add realistic ambience. Position them at the sides of the lis-
tener, or slightly behind, about 2–3 feet (60–100 cm) above
ear level. Ideally they should be equidistant from the listener.
Right
Left
Wall-mounting the surround speakers
If the surround speakers are to be wall-mounted, make sure
that the walls are strong enough to support the speaker’s
weight. The weight that mounting screws can support varies
greatly depending on the wall material and the position of the
reinforcing ribs embedded in the wall.
Use long screws with a head diameter of 1/4 inch (6.3 mm) or
less and a shank diameter of 1/8 inch (3.5 mm) or less. (We
recommend that you consult a home installation profes-
sional.)

Connecting the
Speakers
Read the following before connecting your speakers:
•Turn off your amp before making any connections.
•Pay close attention to speaker wiring polarity. Connect
positive (+) terminals to only positive (+) terminals,
and negative (–) terminals to only negative (–) termi-
nals. If the speakers are wired incorrectly, the sound
will be out of phase and will sound unnatural.
•Be careful not to short the positive
and negative wires. Doing so may
damage your amp.
Connecting the Power
Cord
Notes:
•Before connecting the power cord, connect all of your
speakers and AV components.
•Turning on the SKW-320X may cause a momentary
power surge that might interfere with other electrical
equipment o the same circuit. If this is a problem, plug
the SKW-320X into a different branch circuit.
Adjustment
To set the level of the subwoofer, use the OUTPUT
LEVEL control. Set it so that bass sounds are evenly bal-
anced with the treble sounds from the other speakers.
Because our ears are less sensitive to very low bass
sounds, there’s a temptation to set the level of the sub-
woofer too high. As a rule of thumb, set the subwoofer
level to what you think is the optimal level, and then
back it off slightly.
Connecting the Speaker Cables
1
Use the cables to connect each speaker’s
input terminals to the corresponding
speaker output terminals on your
HT-R320 or other receiver.
To make a connection, while
pressing the terminal lever,
insert the wire into the hole, and
then release the lever.
Make sure that the terminals are
gripping the bare wires, not the insulation.
Connecting the Subwoofer
1
Using the supplied RCA cable, connect
the subwoofer’s LINE INPUT to your
amp’s SUBWOOFER PREOUT.

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.
