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. Dont use abrasive cloths, thin- ners, alcohol, or other chemical solvents, because they may damage the nish or remove the panel let- tering. Use a vacuum cleaner to remove dust from hard-to- reach grilles.

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 units rear panel (e.g., AC 230 V, 50 Hz or AC 120 V, 60 Hz).

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.

Some models have a voltage selector switch for compatibility with power systems around the world. Before you plug in such a model, make sure that the voltage selector is set to the correct voltage for your area.

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.

ATTENTION:

POUR VITER LES CHOCS LEC- TRIQUES, INTRODUIRE LA LAME LA PLUS LARGE DE LA FICHE DANS LA BORNE CORRE- SPONDANTE DE LA PRISE ET POUSSER JUSQUAU FOND.

For British models

Replacement and mounting of an AC plug on the power supply cord of this unit should be performed only by qualied service personnel.

IMPORTANT

The wires in the mains lead are coloured in accordance with the following code:

Blue: Neutral Brown: Live

As the colours of the wires in the mains lead of this apparatus may not correspond with the coloured mark- ings identifying the terminals in your plug, proceed as follows: The wire which is coloured blue must be connected to the terminal which is marked with the letter N or coloured black. The wire which is coloured brown must be connected to the terminal which is marked with the letter L or coloured red.

IMPORTANT

The plug is tted with an appropriate fuse. If the fuse needs to be replaced, the replacement fuse must approved by ASTA or BSI to BS1362 and have the same ampere rating as that indicated on the plug. Check for the ASTA mark or the BSI mark on the body of the fuse. If the power cords plug is not suitable for your socket outlets, cut it off and t a suitable plug. Fit a suitable fuse in the plug.

Precautions

Continued

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, humidier, bathroom, or kitchen.

Do not put water or other liquids close to the sub- woofer. If liquid is spilled over the subwoofer, the drive units may be damaged.

Subwoofer should only be placed on sturdy, at sur- faces that are free from vibration. Putting it on uneven or unstable surfaces, where it 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 subwoofer is used near a turntable, CD player or DVD player, howling or slipping of sound may occur. To prevent this, move it away from the turntable, CD player or DVD player, otherwise lower the units out- put level.

Supplied Accessories

Connections

For safety considerations, turn off all other system com- ponents before you connect or disconnect any compo- nent and plug the power cable for the last.

When using the SKW-204 in conjunction with an AV amplier or receiver that features surround capability, connect the SKW-204 LINE INPUT to SUBWOOFER PREOUT jack using the supplied pin connector cable.

Subwoofer effects

Adding a subwoofer to your speaker system expands the bandwidth of the bass range. However, if the sub- woofers reproduction bandwidth or sound output level is improperly adjusted, the overall performance may decrease, as shown in the graphs below.

Adjustments

Crossover frequency and output level

Adjust the SKW-204 output level and crossover fre- quency to suit your listening room and connected speakers.

Be aware that you might set the subwoofer to a high output level because superbass-range sound is less audible than other sound ranges. To obtain well-bal- anced frequency characteristics, set the output level to a slightly lower level than seems optimal. (This will also prevent the input of signals that are too strong.)

Note:

Be careful not to allow the input of excessive power. Input levels that greatly exceed normal situations can damage the SKW-204. Also note that switching opera- tions at the amplier may generate excessive noise that may result in damage. When using switches at the amplier, rst lower the volume to prevent accidental damage.

Placement

The placement of the SKW-204 can greatly affect the sound that is produced. 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.

Troubleshooting

The unit does not turn on

The power plug is not fully inserted.

Insert the power plug fully into the power outlet.

No sound is output

The OUTPUT LEVEL knob is set to the MIN level.

Set the OUTPUT LEVEL knob properly.

Pin connector cable is not properly connected to the LINE INPUT jack.

The speaker setting at the amplier (or receiver) is incorrect.

Check the settings at the amplier (or receiver).

The input signal is so small that the unit entered Standby mode.

Slightly increase the output level at the amplier (or receiver).

Low sound output

The sound source might not include a superbass range.

Play a sound source that includes a superbass range.

Hum noise

Pin connector plug is not inserted completely.

Fully insert the pin connector plug.

External leakage ux (induction noise by TV, etc.) occurs.

Relocate the SKW-204 away from the noise source and re-connect.
