ONKYO HT-S3300 User Manual

En

• The subwoofer cabinet is made out of wood and is there-

fore 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 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 vertical 

position only. Do not use it in the horizontal or tilted 
position.

• If the unit is used near a turntable, CD player or Blu-ray 

Disc/DVD player, howling or slipping of sound may 
occur. To prevent this, move the unit away from the turn-
table, CD player or Blu-ray Disc/DVD player, otherwise 
lower the unit’s output level.

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-380 and SKC-380/
SKC-380C 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 nor-
mally activates the degaussing function, which neutralizes 
the magnetic field, thereby removing any discoloration 
effects. If discoloration problems persist, try moving the 
speakers away from your TV or monitor. Note that discol-
oration can also be caused by a magnet or demagnetizing 
tool that’s too close to your TV or monitor.
Do not place SKR-380 close to TV or a computer monitor 
because they have no magnetic shield.

The speakers can handle the specified input power when 
used for normal music reproduction. If any of the follow-
ing 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, elec-

tronic 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.

Make sure you have the following items:

*

In catalogs and on packaging, the letter at the end of the prod-
uct name indicates the color. Specifications and operations are 
the same regardless of color.
