ONKYO SKS-4800 ユーザーズマニュアル

Thank you for your purchase of the Onkyo speaker 
system.
Please read this manual thoroughly before using it.
Following the instructions in this manual will 
enable you to obtain optimum performance and 
listening enjoyment from your new speaker 
system.
Please retain this manual for future reference.

• The speaker cabinet is made of wood and is 

therefore sensitive to extreme temperatures and 
humidity. Avoid placing the speaker systems in 
locations subjected to direct sunlight, or in smoky 
or in humid places, such as near an air conditioner, 
humidifier, bathroom, or kitchen. Doing so may 
result in damage to the speaker.

• Place the unit on a rigid, level surface. Placing it 

on a slanted surface or weak base not only may 
cause the unit to fall, but also results in decreased 
sound quality.

• Be sure to turn off your amplifier before 

connecting the speaker system. Connecting them 
with the amplifier’s power on may result in 
damage to the amplifier or the speaker system.

• Keep water or other liquids away from the unit. If 

water is spilled into the unit, not only the unit but 
also the speakers themselves may be damaged.

• This speaker system can handle the specified 

input power when it is used for ordinary music 
reproduction. If the following abnormal signals 
are fed to the speaker, 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. Noise produced when FM station is not tuned in
2. Sound produced when fast-forwarding cassette 

tape deck

3. High-frequency sound generated by an 

oscillator, an electronic musical instrument, etc.

4. Oscillating amplifier signals
5. Special test signals produced by audio checking 

CD, etc.

6. Sound produced when connecting or 

disconnecting audio connection cables (Always 
turn off the amplifier’s power before connecting 
or disconnecting cables.)

7. Howling when a microphone is used

• Do not place magnetic objects such as 

screwdrivers and iron parts near the tweeter since 
they use speakers with strong magnets. Otherwise, 
the objects may be attracted, causing injury or 
damaging the diaphragm.
