Getting to know Your Speaker Package
A
Speaker terminals
These push terminals
are for connecting the
speaker to your AV
Receiver, amp, or
other receiver with the
supplied speaker
cables. The supplied
speaker cables are
color-coded for easy
identification. Simply
connect each cable to
the same-colored posi-
tive speaker terminal.
B
Speaker mount/bracket inserts
These threaded inserts can be used to attach the
speaker to a speaker mount or bracket.
Note:
Use commercially available 1/4" screws to attach
the speaker to a speaker mount or bracket.
C
Keyhole slots
These keyhole slots can be used to wall-mount the
speaker.
Use the center speaker base to mount the center speaker
horizontally. If you place the speaker and its base on top
of a TV or an entertainment center, adjust the angle of
the speaker so that it faces toward the listening position.
The center speaker should be installed on the base
securely. If the speaker is loose, try adjusting the posi-
tion so that it sits securely on the base.
The cradle surface of the base features two stoppers to
prevent the speaker from moving. Therefore, you can
tilt the speaker toward the front by up to 15 degrees.
■ Using the included rubber spacers
We recommend using the
supplied rubber spacers to
achieve the best possible
sound from your speak-
ers. The rubber spacers
prevent the speakers from
moving, providing a more
stable setup.
The speakers can easily be wall mounted by using the
keyhole slots. To prevent the speaker from vibrating
against the wall, attach four of the supplied rubber spac-
ers to the rear of each speaker.
■ Mounting vertically
To mount the speakers vertically, use the one keyhole
slot shown to hang each speaker on the screw that is
securely screwed into the wall.
■ Mounting horizontally
To mount the speakers horizontally, use the two keyhole
slots shown to hang each speaker on two screws that are
securely screwed into the wall.
The plaque of each speaker rotates so that you can posi-
tion the speakers upside down.
Caution:
A mounting screw’s ability to support a speaker
depends on how well it’s anchored to the wall. If you
have hollow walls, screw each mounting screw into a
stud. If there are no studs, or the walls are solid, use
suitable wall anchors.
Use screws with a head diameter of 3/8" or less and a
shank diameter of 1/8" or less. With hollow walls, use a
cable/pipe detector to check for any power cables or
water pipes before making any holes.
Leave a gap of 1/4"–5/16"
between the wall and the
base of the screw head, as
shown.
(We recommend that you
consult a home installation
professional.)

STANDBY/ON indicator
Red: Subwoofer in standby mode
Green: Subwoofer on
With the Auto Standby function, the SKW-540
automatically turns on when an input signal is
detected in Standby mode. When there’s no input
signal for a while, the SKW-540 automatically
enters Standby mode.
B OUTPUT LEVEL control
This control is used to adjust the volume of the sub-
woofer.
C LINE INPUT
This RCA input should be connected to the sub-
woofer preout on your AV receiver, amp, or other
receiver with supplied RCA cable.
Note:
The Auto Standby function turns the subwoofer on
when the input signal exceeds a certain level. If the
Auto Standby function does not work reliably, try
slightly increasing or decreasing the subwoofer out-
put level on your receiver or amp.
Connecting the Speakers
Read the following before connecting your speakers:
• Turn off your amp before making any connections.
• Disconnect the power cord from the wall outlet before
making any connections.
• Pay close attention to speaker wiring polarity. Connect
positive (+) terminals to only positive (+) terminals,
and negative (–) terminals to only negative (–) termi-
nals. If the speakers are wired incorrectly, the sound
will be out of phase and will sound unnatural.
• Be careful not to short the posi-
tive and negative wires. Doing so
may damage your amp.
Use the cables to connect each speaker’s input
terminals to the corresponding speaker output
terminals on your receiver.
To make a connection, while pressing
the terminal lever, insert the wire into
the hole, and then release the lever.
Make sure that the terminals are grip-
ping the bare wires, not the insulation.
Using the supplied RCA cable, connect the sub-
woofer’s LINE INPUT to your receiver’s SUB-
WOOFER PREOUT.

About Home Theater
The HTP-640’s great sound means that you can enjoy surround sound with a real sense of movement in your own
home—just like being in a movie theater or concert hall.
Connecting the Power
Cord
Notes:
• Before connecting the power cord, connect all of your
speakers and AV components.
• Turning on the SKW-540 may cause a momentary
power surge that might interfere with other electrical
equipment on the same circuit. If this is a problem,
plug the SKW-540 into a different branch circuit.
Adjustment
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
subwoofer 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.

Front left and right speakers (SKF-640F)
These output the overall sound.Their role in a home theater is
to provide a solid anchor for the sound image.They should be
positioned facing the listener at about ear level, and equidis-
tant from the TV. Angle them inward so as to create a triangle,
with the listener at the apex.
Center speaker (SKC-640C)
This speaker enhances the front left and right
speakers, making sound movements distinct and
providing a full sound image. In movies it’s used
mainly for dialog.
Position it close to your TV facing forward at about
ear level, or at the same height as the front left and
right speakers.
Put it somewhere where it won’t slide around or fall.
Subwoofer (SKW-540)
The subwoofer handles the bass sounds
of the LFE (Low-Frequency Effects)
channel. The volume and quality of the
bass output from your subwoofer will
depend on its position, the shape of your
listening room, and your listening posi-
tion. In general, a good bass sound can
be obtained by installing the subwoofer
in a front corner, or at one-third the width
of the wall, as shown.
Surround left and right speakers (SKM-640S)
These speakers are used for precise sound positioning
and to add realistic ambience. Position them at the
sides of the listener, or slightly behind, about 2–3 feet
(60–100 cm) above ear level. Ideally they should be
equidistant from the listener.

Caring for Your Speakers
Placement
• The subwoofer cabinet is made out of wood and is
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 or CD player, howl-
ing or slipping of sound may occur. To prevent this,
move the unit away from the turntable or CD 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-640F, SKC-640C and
SKM-640S speakers 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 per-
sist, 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 yourTV
or monitor.
Operating Precautions
The HTP-640 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 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,
electronic 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.
Speaker care
Wipe the cabinet occasionally with a dry silica or soft
cloth. For heavier dirt, after dampening a soft cloth in a
weak solution of mild detergent and water and wringing
it out dry, wipe off the dirt. Then, dry immediately with
a clean cloth. Do not use rough material, thinners, alco-
hol or other chemical solvents or cloths since these could
damage the finish, remove the panel lettering, or cause
discoloration. If you are using a chemical cloth, always
follow the instructions that come with the cloth. For dust
accumulated on grilles, use a vacuum cleaner or brush it
off.
