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.

• 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 conditioner, 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 damage, will affect the sound quality.
• Subwoofer is designed to be used in the upright vertical 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-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 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.

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 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 disconnecting 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, alcohol 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 speakers.
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, causing 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 window, etc.

Make sure your box contains all of the items below. If anything is missing, contact the nearest Onkyo dealer.

Front, Center, Surround, and Surround back speakers (SKF-750XF, SKC-750XC, SKM-750XS, SKB-750X)

① Keyhole slots

These keyhole slots can be used to wall-mount the speaker.

They can also be used to install the speaker on the stand.

② Speaker terminals

These push terminals are for connecting the speaker to your AV Receiver with the supplied speaker cables. The supplied speaker cables are color-coded for easy identification. Simply connect each cable to the same-colored positive speaker terminal.

③ Speaker mount/bracket inserts

These threaded inserts can be used to attach the speaker either horizontally or vertically to a speaker mount or bracket.

Note:

Use commercially available 1/4'' screws to attach the speaker to a speaker mount or bracket.

Speaker Stand

Follow the steps below to install each front speaker onto a speaker stand.

1 Loosen the bundled speaker cable, insert the cable into the hole of the base panel from the top, then pull the cable out and downward.

Do not pull the speaker cable too hard, as it may break.

2 Attach the pipe stand to the base panel in the correct orientation so that the screw holes on the pipe stand and the holes in the base panel will align. Tighten the screws firmly.

3 Guide the speaker cable along the arrow on the base panel bottom, and snap the cable into the notch on the perimeter of the base panel bottom.

4

While pressing in the lever on the speaker terminal on the rear panel of the speaker, connect the speaker cable to the terminal.

The supplied speaker cables are color-coded for easy identification. Simply connect each cable to the same-colored positive speaker terminal.

5

(1) Insert the hook on the pipe stand into the key hole on the speaker's rear panel, then (2) press and slide the speaker downward.

(2) Press and slide the speaker downward.

Note:

Be careful not to pinch the speaker cable between the pipe stand cover and the speaker's rear panel.

6

Attach the pipe stand to the speaker securely using the included screw (large).

7

Completed.

Caution:

To remove the speaker from the stand, remove the screw, slide the speaker upward to release the hook, and reverse the steps for installing the speaker to the stand.

Center Speaker Base

The center speaker base is for mounting the center speaker horizontally. If you put it on a TV stand or AV stand, aim it toward the listening position. The center speaker should sit securely on the base. If it's loose, try resetting it.

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 11 degrees.

Using the included rubber spacers

We recommend using the supplied rubber spacers to achieve the best possible sound from your speakers. The rubber spacers prevent the speakers from moving, providing a more stable setup.

Wall Mounting

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 spacers to the keyhole fins on the rear of each speaker.

Mounting vertically

To mount the front speakers vertically, use the keyhole slot shown to hang each speaker on a screw that's securely screwed into the wall.

Mounting horizontally

To mount the center speaker horizontally, use the two keyhole slots shown to hang each speaker on two screws that are securely screwed into the wall.

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'' (9 mm) or less and a shank diameter of 1/8'' (3.5 mm) 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 between 1/4'' and 5/16'' (6–8 mm) between the wall and the base of the screw head, as shown.

(We recommend that you consult a home installation professional.)

Using Rubber Spacers with the Speakers

We recommend using the supplied rubber spacers to achieve the best possible sound from your speakers. The rubber spacers prevent the speakers from moving, providing a more stable setup.

Subwoofer (SKW-750X)

Front

If the subwoofer is placed on a hard floor (wood, vinyl, tile, etc.) and playback is very loud, the subwoofer's feet may damage the flooring. To prevent

this, place the supplied pads 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 balanced 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.

Rear

To AC outlet

① STANDBY/ON indicator

Red: Subwoofer in standby mode

Blue: Subwoofer on

With the Auto Standby function, the SKW-750X automatically turns on when an input signal is detected in Standby mode. When there's no input signal for a while, the SKW-750X automatically enters Standby mode.

② OUTPUT LEVEL control

This control is used to adjust the volume of the subwoofer.

③ LINE INPUT

This RCA input should be connected to the subwoofer pre out on your AV 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 output level on the AV receiver.

Read the following before connecting your speakers:

• Turn off your receiver or 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 (-) terminals. If the speakers are wired incorrectly, the sound will be out of phase and will sound unnatural.
• Be careful not to short the positive and negative wires. Doing so may damage your amp.

For more information, please refer to the TX-SR606 Instruction Manual.

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 gripping the bare wires, not the insulation.

Connecting the Subwoofer

Using the supplied RCA cable, connect the subwoofer's LINE INPUT to your receiver's SUB-WOOFER PRE OUT.
