Appendix

Troubleshooting 12
Specifications 13

Placement

• The speaker cabinets are made out of wood 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 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. In such situations, try moving the speakers away from your TV or monitor. If discoloration should occur, 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. Note that discoloration can also be caused by a magnet or demagnetizing tool that's too close to your TV or monitor.

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-770 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-770 into a different branch circuit.

The Home Theater 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.

Front left and right speakers (SKF-770)

These output the main 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 equally spaced from the TV. Angle them inward slightly so as to create a triangle, with the listener at the apex.

Surround left and right speakers (SKR-770)

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 to 3 feet (60 to 100~cm ) above ear level. Ideally they should be equally spaced from the listener.

Center speaker (SKC-770)

This speaker enhances the front left and right speakers, making sound movements distinct and providing a full sound image. For movies it's used mainly for dialog.

Position it close to your TV (preferably on top) facing forward at about ear level, or at the same height as the front left and right speakers.

Subwoofer (SKW-770)

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 position. In general, a good bass sound can be obtained by installing the subwoofer in a front corner, or at one-third the way along the front wall, as shown.

Tip: To find the best position for your subwoofer, while playing a movie or some music with good bass, experiment by placing your subwoofer at various positions within the room and choose the one that provides the most satisfying results.

Surround back left and right speakers (SKB-770)

These speakers are necessary to enjoy Dolby Digital EX, DTS-ES Matrix, DTS-ES Discrete, etc. They enhance the realism of surround sound and improve sound localization behind the listener. Position them behind the listener about 2 to 3 feet (60 to 100cm ) above ear level.

① Keyhole slots

These keyhole slots can be used to wall-mount the speaker (see page 11).

② Speaker terminals

These push terminals are for connecting the speaker to the 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.

Caution:

The front grilles are not designed to be removed so do not attempt to remove them forcibly, as this will damage them.

Attaching the Speaker Bases

Before you connect the speakers, attach the supplied speaker base to each SKF-770.

1. Turn the speaker upside down with the protection cover attached.
2. Align the speaker base while the arrow mark is headed in the same direction as the speaker's face. Be careful not to tip over the speaker.
3. Align the screw holes on the speaker base with those on the bottom of each speaker, and affix the speaker base using the supplied screws. Recommended torque is 10kgf· cm (9 lbf·in). Be careful not to tip over the speaker.
4. Turn the speaker right side up.
5. Remove the protection cover.

SAFETY PRECAUTIONS:

• Attach the speaker bases in a manner that will not allow the speakers to tip over.
• Be sure to tighten the screws when you attach the speaker bases.
• Attach the speaker bases on a flat, level, and stable floor.
• After you attach the speaker bases, make sure that the speakers stand upright and are stable.

① OUTPUT LEVEL control

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

② 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 your receiver.

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.

OUTPUT LEVEL

Speaker Connection Precautions

Read the following before connecting your speakers:

• Turn off your receiver 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 un

• Be careful not to short the positive and negative wires. Doing so may damage your amp.

Connecting the Speaker Cables

Use the supplied speaker cables to connect each speaker 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 PRE OUT: SUBWOOFER.

HT-S7200: If you are using an Onkyo HT-S7200 system, you can connect the powered subwoofer with two PRE OUT: SUBWOOFER jacks respectively. When using a single subwoofer, you can connect either jack. The other jack is for connecting additional subwoofer.

Wall Mounting

The speakers (center, surround, and surround back) can easily be wall mounted by using the keyhole slots.

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

Surround speakers/Surround back speakers (SKR-770/SKB-770)

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.

Center speaker (SKC-770)

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 5/16'' (8 mm) or less and a shank diameter of 5/32'' (4 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 7/32" (5 mm) and 3/8" (10 mm) between the wall and the base of the screw head, as shown. (We recommend that you consult a home installation professional.)

Using the Cork Stoppers for a More Stable Platform

We recommend using the provided cork stoppers to achieve the best possible sound from your speakers. The cork stoppers prevent the speakers from moving, providing a more stable platform. Use stoppers for the center speaker.

Using the Floor Pads for Subwoofer

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.
