Precautions  
Speaker Precautions  
1. AC Fuse—The AC fuse inside the unit is not user-  
serviceable. If you cannot turn on the unit, contact  
your Onkyo dealer.  
Placement  
• The subwoofer cabinet is made out of wood and is  
therefore 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 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.  
2. Care—Occasionally you should dust the unit all  
over with a soft cloth. For stubborn stains, use a soft  
cloth dampened with a weak solution of mild deter-  
gent and water. Dry the unit immediately afterwards  
with a clean cloth. Don’t use abrasive cloths, thin-  
ners, alcohol, or other chemical solvents, because  
they may damage the finish or remove the panel let-  
tering.  
3. Power  
WARNING  
BEFORE PLUGGING IN THE UNIT FOR THE  
FIRST TIME, READ THE FOLLOWING SEC-  
TION CAREFULLY.  
AC outlet voltages vary from country to country.  
Make sure that the voltage in your area meets the  
voltage requirements printed on the unit’s rear panel  
(e.g., AC 230 V, 50 Hz or AC 120 V, 60 Hz).  
• 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.  
The power cord plug is used to disconnect this unit  
from the AC power source. Make sure that the plug  
is readily operable (easily accessible) at all times.  
Auto standby function does not fully shutdown the  
SKW-750X. If you do not intend to use the SKW-  
750X, remove the power cord from the AC outlet.  
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-750XF and  
SKC-750XC 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 your  
TV or monitor.  
For Canadian models  
For models having a power cord with a polarized plug:  
CAUTION: TO PREVENT ELECTRIC SHOCK,  
MATCH WIDE BLADE OF PLUG TO WIDE SLOT,  
FULLY INSERT.  
Modèle pour les Canadien  
Sur les modèles dont la fiche est polarisée:  
ATTENTION: POUR ÉVITER LES CHOCS ÉLEC-  
TRIQUES, INTRODUIRE LA LAME LA PLUS  
LARGE DE LA FICHE DANS LA BORNE CORRE-  
SPONDANTE DE LA PRISE ET POUSSER  
JUSQU’AU FOND.  
Do not place SKM-750XS/SKB-750X close to TV or a  
computer monitor because they have no magnetic shield.  
Input Signal Warning  
The speakers can handle the specified input power when  
used for normal music reproduction. If any of the fol-  
lowing 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.  
3
 
   
Speaker Precautions—Continued  
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.  
Power Cord Precautions  
• Before connecting the power cord, connect all of your  
speakers and AV components.  
• Turning on the SKW-750X 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-750X into a different branch circuit.  
Speaker Stand AS-140 Precautions  
1. Be sure to tighten the screws when you assemble the  
speaker stands and attach the brackets to the speak-  
ers.  
2. The speaker stands are tall. Install the stands in a  
manner that will not allow the speakers to tip over.  
You may want to use commercially available chains  
to prevent the stands from falling in the event of an  
earthquake.  
3. Do not place the stands on an unstable table, slope,  
or thick carpet. Otherwise, the stands may fall, caus-  
ing injury.  
4. Place the stands in a location in which they would  
not cause injury if they accidentally fell.  
5. Do not place the stands in an area at risk of fire or  
damage, such as near a fireplace, heater, glass win-  
dow, etc.

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" (9 mm) or less  
and a shank diameter of 1/8" (3.5 mm) or less. With hol-  
low walls, use a cable/pipe detector to check for any  
power cables or water pipes before making any holes.  
Leave a gap of between 1/4" and 5/16" (6–8 mm)  
between the wall and the base of the screw head, as  
shown.  
Mounting vertically  
To mount the front speakers vertically, use the keyhole  
slot shown to hang each speaker on a screw that’s

Subwoofer (SKW-750X)  
If the subwoofer is placed on a hard floor (wood,  
vinyl, tile, etc.) and playback is very loud, the sub-  
woofer's feet may damage the flooring. To prevent  
this, place the supplied pads  
Front  
underneath the subwoofer's feet.  
The pads also provide a stable  
base for the subwoofer.  
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.

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 pre out on your AV receiver with supplied  
RCA cable.  
Note:  
TheAuto 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 output level on  
the AV receiver.

Connecting the Speakers  
Read the following before connecting your speakers:  
• Turn off your receiver or amp before making any con-  
nections.  
Connecting the Speaker Cables  
Use the supplied cables to connect each  
speaker’s input terminals to the corresponding  
speaker output terminals on your receiver.  
Match the color of each cable to the corresponding  
speaker terminal.  
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.  
• 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.  
Connecting the Subwoofer  
Using the supplied RCA cable, connect the sub-  
woofer’s LINE INPUT to your receiver’s SUB-  
WOOFER PRE OUT.
