unused for long periods of time.
14. Refer all servicing to qualified service personnel.
Servicing is required when the apparatus has been
damaged in any way, such as power-supply cord or

have fallen into the apparatus, the apparatus has been
exposed to rain or moisture, does not operate
normally, or has been dropped.
15. Damage Requiring Service

servicing to qualified service personnel under the
following conditions:
A. When the power-supply cord or plug is damaged,
B. If liquid has been spilled, or objects have fallen
into the apparatus,
C. If the apparatus has been exposed to rain or water,
D. If the apparatus does not operate normally by

require extensive work by a qualified technician to
restore the apparatus to its normal operation,
E. If the apparatus has been dropped or damaged in
any way, and
F. When the apparatus exhibits a distinct change in
performance this indicates a need for service.

such as a bookcase or rack, ensure that there is
adequate ventilation.
Leave 20 cm (8") of free space at the top and sides and
10 cm (4") at the rear. The rear edge of the shelf or
board above the apparatus shall be set 10 cm (4")
away from the rear panel or wall, creating a flue-like

Precautions
1. Recording Copyright—Unless it’s for personal use
only, recording copyrighted material is illegal without
the permission of the copyright holder.
2. AC Fuse—The AC fuse inside the unit is not user-
serviceable. If you cannot turn on the unit, contact
your Onkyo dealer.
3. Care—Occasionally you should dust the unit all over
with a soft cloth. For stubborn stains, use a soft cloth
dampened with a weak solution of mild detergent and
water. Dry the unit immediately afterwards with a
clean cloth. Don’t use abrasive cloths, thinners,
alcohol, or other chemical solvents, because they may
damage the finish or remove the panel lettering.

WARNING
BEFORE PLUGGING IN THE UNIT FOR THE
FIRST TIME, READ THE FOLLOWING SECTION
CAREFULLY.
AC outlet voltages vary from country to country.
Make sure that the voltage in your area meets the
voltage requirements printed on the unit’s rear panel
(e.g., AC 230 V, 50 Hz or AC 120 V, 60 Hz).
The power cord plug is used to disconnect this unit
from the AC power source. Make sure that the plug is
readily operable (easily accessible) at all times.
For models with [POWER] button, or with both
[POWER] and [ON/STANDBY] buttons:
Pressing the [POWER] button to select OFF mode
does not fully disconnect from the mains. If you do
not intend to use the unit for an extended period,
remove the power cord from the AC outlet.
For models with [ON/STANDBY] button only:
Pressing the [ON/STANDBY] button to select
Standby mode does not fully disconnect from the
mains. If you do not intend to use the unit for an
extended period, remove the power cord from the AC
outlet.
• Subwoofer is designed to be used in the upright vertical
position only. Do not use it in the horizontal or tilted
position.
• If the subwoofer is used near a turntable, CD player or
DVD player, howling or slipping of sound may occur.
To prevent this, move it away from the turntable, CD
player or DVD player, otherwise lower the unit’s output
level.
Connection
With other audio-video components, connect the
subwoofer’s LINE INPUT to the subwoofer pre out jack
of your equipment. Never plug any kind of musical
instrument to the subwoofer.
Supplied Accessories
• Power cords
(The plug type varies from country to country. From the
two supplied power cords, choose the one whose plug
matches the type of your AC wall outlet.)

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
conditioner, humidifier, bathroom, or kitchen.
• Do not put water or other liquids close to the subwoofer.
If liquid is spilled over the subwoofer, the drive units
may be damaged.
• Subwoofer should only be placed on sturdy, flat surfaces
that are free from vibration. Putting it on uneven or
unstable surfaces, where it may fall and cause damage,
will affect the sound quality.
If the subwoofer is placed
on a hard floor (wood,
vinyl, tile, etc.) and
playback is very loud, the
subwoofer’s feet may
damage the flooring.
To prevent this, place the supplied pads underneath the
subwoofer’s feet. The pads also provide a stable base for
the subwoofer.
