Speaker Precautions

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, CD player or DVD player, howling or slipping of sound may occur. To prevent this, move the unit away from the turntable, CD player or DVD 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-550F and SKC-550C 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 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.

Input Signal Warning

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.
