Onkyo SKW-320 Manual De Instrucciones página 6

Adding a subwoofer to your speaker system expands the bandwidth of reproduced bass-range sound. If the subwoofer's
reproduction bandwidth or sound output level is improperly adjusted, however, the overall performance may be decreased
as shown in the graphs below.

mm Crossover frequency and output level
+ Adjust the SKW-320/310's output level and the crossover
frequency properly for your listening room and connected
speakers.
+ When the unit is connected to an amplifier via the speaker-
level input (INPUT FROM RECEIVER) terminalis, setting the
OUTPUT LEVEL knob near the center position will provide a
well-balanced sound level with most speakers.
Note that you may possibly set the subwoofer at high output
levels because superbass-range sound is not so audible as
sound in other ranges. To obtain well-balanced frequency
characteristics, set the output level to a slightly lower level
than seems optimal. (This will also prevent the input of too
strong signals.)
.
Hw Operation
Avoid inputting strong signals. Although the SKW-320/310's
built-in limiter protects the driver unit and output circuit from
strong signal input, damage may result if extraordinarily
strong signals are input.
Depending on the amplifier used, noises may be generated
by changeover of its switches. Before you change the
amplifier's switch setting, be sure to turn the volume conirol
knob down to the minimum to prevent damage to the
speakers.
This unit has two drivers on its right and left sides. Do not
block these drivers with the wall or furniture (a clearance of
10 cm (4 inches) or more is required).
Glass is used on the top of SKW-320. Be careful not to hit
the glass with hard objects since it breaks easily.

Precaution on use
MH Placement
The enclosure is made of wood and therefore sensitive to
extreme temperatures and humidity. Avoid placing the unit in
locations subjected to direct sunlight or in humid places such as
near an air conditioner, bathroom or kitchen, as well as in
locations subjected to soot or steam such as near a kitchen
table and humidifier. Otherwise, damage may occur.
Keep water or other liquids away from the unit. If water is spilled
into the unit, not only the unit but also the connected receiver
(amplifier) may be damaged.
Place the unit on a level and rigid surface free from vibration.
This unit is designed to be used in the upright vertical position
only. Do not use it in the horizontal or tilted position.
if the unit is used near a tumtable or CD player, howling or
skipping of sound may occur. To prevent this, move the unit
away from the turntable or CD player or otherwise lower the
unit's output level.
This unit can handle the specified input power when it is used
for ordinary music reproduction. If the following abnormal
signals are fed to the unit, however, an overcurrent may flow in
the internal circuits, causing burning or breakage of the wires
even if the input power is below the specified rating.
1. Special test signals produced by audio checking CD, etc.
2. Sound produced when connecting or disconnecting audio
connection cables
(Always turn off the amplifier's power before connecting or
disconnecting cabies.)
3. Howling when a microphone is used
4, Abnormal! sound produced when bass-range signals are
excessively boosted by using the receiver's (amplifier's)
tone controls, a graphic equalizer, etc., or when a source
whose bass range is abnormally boosted is being played
This state called "rattling" occurs when the signal is beyond
the driver's reproduction capacity. Although it is not a sign
of damage, decrease the speaker output level to prevent
damage to the driver.
