Precautions 1. Recording CopyrightUnless its for personal use

only, recording copyrighted material is illegal without the permission of the copyright holder.

2. AC FuseThe AC fuse inside the unit is not user- serviceable. If you cannot turn on the unit, contact your Onkyo dealer.

3. CareOccasionally 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 detergent and water. Dry the unit immediately afterwards with a clean cloth. Dont use abrasive cloths, thinners, alcohol, or other chemical solvents, because they may damage the finish or remove the panel lettering.

4. Power WARNING BEFORE PLUGGING IN THE UNIT FOR THE FIRST TIME, READ THE FOLLOWING SECTION 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.

For models with [POWER] button, or with both [POWER] and [ON/STANDBY] buttons: Pressing the [POWER] button to select OFF mode does not fully disconnect from the mains. If you do not intend to use the unit for an extended period, remove the power cord from the AC outlet.

For models with [ON/STANDBY] button only: Pressing the [ON/STANDBY] button to select Standby mode does not fully disconnect from the mains. If you do not intend to use the unit for an extended period, remove the power cord from the AC outlet.

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 conditioner, humidifier, bathroom, or kitchen.

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

Subwoofer should only be placed on sturdy, flat surfaces that are free from vibration. Putting it on uneven or unstable surfaces, where it 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 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 output level.

Connection

With other audio-video components, connect the subwoofers LINE INPUT to the subwoofer pre out jack of your equipment. Never plug any kind of musical instrument to the subwoofer.

Supplied Accessories Power cords (The plug type varies from country to country. From the two supplied power cords, choose the one whose plug matches the type of your AC wall outlet.)

Pin connector cable 3 m

4 floor pads for the subwoofer

* In catalogs and on packaging, the letter added to the end of the product name indicates the color of the SKW-770. Specifications and operation are the same regardless of color.

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 subwoofers feet may damage the flooring. To prevent this, place the supplied pads underneath the subwoofers feet. The pads also provide a stable base for the subwoofer.

Controls

FRONT VIEW

a Standby/On indicator Red: Subwoofer in standby mode Blue: Subwoofer on The Auto Standby function will automatically set the SKW-770 to Standby mode when there is no input signal, or when the input signal is below a certain level.

Note

If the Auto Standby function sets the SKW-770 to Standby mode even when an input signal is present, the input signal level is too low. In this case, increase the subwoofer output level on the amplifier or AV receiver connected to the SKW-770.

Connections For safety considerations, turn off all other system components before you connect or disconnect any component and plug the power cord for the last.

When using the SKW-770 in conjunction with an AV amplifier or receiver that features surround capability, connect the SKW-770 LINE INPUT to SUBWOOFER PREOUT jack using the supplied pin connector cable.

Caution

With other audio-video components, connect the subwoofers LINE INPUT to the subwoofer pre out jack of your equipment. Never plug any kind of musical instrument to the subwoofer.

Note

Before connecting the power cord, connect all of your speakers and AV components.

Turning on the subwoofer may cause a momentary power surge that might interfere with other electrical equipment on the same circuit. If this is a problem, plug the subwoofer into a different branch circuit.

Do not use a power cord other than the one supplied with the subwoofer. The supplied power cord is designed exclusively for use with the subwoofer and should not be used with any other equipment.

Never disconnect the power cord from the subwoofer while the other end is still plugged into a wall outlet. Doing so may cause an electric shock. Always disconnect the power cord from the wall outlet first, and then the subwoofer.

Adjustments To set the level of the subwoofer, use the OUTPUT LEVEL knob. 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, theres 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.

Note

Be careful not to allow the input of excessive power. Input levels that greatly exceed normal situations can damage the SKW-770. Also note that switching operations at the amplifier may generate excessive noise that may result in damage. When using switches at the amplifier, first lower the volume to prevent accidental damage.

Placement The placement of the SKW-770 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.

Specifications

Specifications and appearance are subject to change without prior notice.

The power plug is not fully inserted. Insert the power plug fully into the power outlet.

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 amplifier (or receiver) is incorrect.

Check the settings at the amplifier (or receiver).

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

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

If the Standby/On indicator lights up (both red and blue LEDs) several seconds or minutes after the sound output stopped, this means that the amp protection circuit has been activated. In this case, set the OUTPUT LEVEL knob to the center position, and disconnect the power cord from the AC outlet. Wait at least 10 seconds, and then reconnect the power cord. If that doesnt solve the issue, contact your Onkyo dealer.

The sound source might not include a superbass range.

Play a sound source that includes a superbass range.

Pin connector plug is not inserted completely. Fully insert the pin connector plug.

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