Setting the Subwoofer Level

To set the level of the subwoofer, use the OUTPUT LEVEL control. Set it so that bass sounds are evenly bal- anced with the treble sounds from the other speakers. Because our ears are less sensitive to very low bass sounds, there’s a temptation to set the level of the sub- woofer too high. As a rule of thumb, set the subwoofer level to what you think is the optimal level, and then back it off slightly.

Caring for Your Speakers

Placement

•The speaker cabinets are made out of aluminum 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.

•As explained in this manual, mount the speakers on a wall, on the supplied bases, or on the optional stands, otherwise, they may fall, causing personal injury or damage to the speakers.

•Speakers with bases 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 damage, will affect the sound quality.

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 HTP-240/SKS-HT240 speak- ers feature internal magnetic shielding. In some situa- tions, 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 neutral- izes the magnetic field, thereby removing any discoloration effects. If discoloration problems persist, try moving the speakers away from your TV or monitor. Note that discoloration can also be caused by a magnet or demagnetizing tool that’s too close to your TV or monitor. The HTP-240/SKS-HT240 speakers contain strong magnets, so do not put magnetic or iron objects such as screwdrivers close to them. If you do, the object may be attracted to the magnets, causing personal injury or dam- age to a speaker cone.

Operating Precautions

The HTP-240/SKS-HT240 speakers can handle the specified input power when used for normal music reproduction. If any of the following signals are fed to them, even if the input power is within the specified rat- ing, 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.
