Caring forYour Speakers
Setting the Subwoofer Level
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.
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.
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, 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.
Subwoofer Level Set OK
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, speakers other than the subwoofer
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.
Repsonse of other speakers
Subwoofer Level Set Incorrectly
Subwoofer level too high
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:
Subwoofer level too low
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.
. Ampliﬁer oscillation.
. Special test tones from audio test CDs and so on.
. Thumps and clicks caused by connecting or discon-
necting audio cables (Always turn off your ampliﬁer
before connecting or disconnecting cables.)
. Microphone feedback.
