Installation

The Subwoofer is a virtually omnidirectional speaker, so it can be installed in almost any location. For example, the Subwoofer can be installed next to the component system (consisting of an amplifier, tuner, cassette deck, etc.), or in a corner of the room, etc.. The subwoofer's deep-bass reproduction characteristics are richest when the subwoofer is installed in a corner or near a wall. Since the low-bass component in music is usually monaural, only one subwoofer is necessary to obtain a sufficient stereo effect when used in combination with a stereo music system.

CAUTION

To assure ventilation, observe the following points when installing the unit.

• Leave a distance of more than 10 cm between the Subwoofer back and the surrounding wall(s). Use special care not to cover the heat sink with a curtain, etc. when installing.
• Do not place the equipment onto a bed, a sofa, a carpet, or similar. Sucked-in dust can cause fire.
• Be sure to install the Subwoofer vertically.

Vertical installation

Howling

If the Subwoofer is installed near an analog record turntable, a howling sound may be generated. If this occurs, place the Subwoofer farther away from the turntable or reduce the Subwoofer volume (By rotating the VOLUME control counterclock-wise). The howling phenomenon may also occur due to cross interference with a cassette deck, compact disc player, or Laserdisc player, although this is very rare. If sound or picture seems to be distorted due to this reason, place the Subwoofer farther away from other components or reduce its volume.

Operation near a TV

If the Subwoofer is installed near a TV set, the TV reception may be affected and interfered with color irregularities. Should color irregularities observed on TV screen, separate the Subwoofer from the TV until its reception becomes normal.

Connections

If your amplifier or receiver outputs only the L/R separated, line-level signals, it is required to use an adapter for synthesizing the L and R signals (not provided) in order to connect the Subwoofer to such an amplifier or receiver.

●In case an associated system component is connected, also read the instruction manual of the component.
- Be sure to insert all connection cords securely. If their connections are imperfect, the sound may not be produced or noise may interfere.

CONNECTION PRECAUTIONS

Do not connect the power cord plug into the power outlet until all other connections are complete.

Before unplugging a cord or cable from the unit, be always sure to set the POWER switch to OFF and unplug the power plug from the power outlet.

CAUTION

Simply setting the POWER switch to OFF does not shut down the power supplied to the unit completely. To isolate this unit completely from the power supply, it is necessary to unplug the power cord from the power outlet.

To shut down the power supply to the unit immediately in case of an emergency, connect the power plug to an easily accessible power outlet.

⑤Power cord

Connect to AC outlet.

Caution concerning operation

An excessive input level to the Subwoofer may impair the sound quality or damage the unit. Careful attention should therefore be paid to the following precautions.

Notes :

• Do not increase the output of the amplifier to a high level while the low-frequency level is enhanced by the amplifier's tone control or loudness control.
• When operating the amplifier switches or when placing the stylus on an analog record, set the amplifier volume to its minimum level.

Maintenance

Maintenance of the unit

When the front panel or case becomes dirty, wipe with a soft, dry cloth. Do not use thinner, benzine, alcohol, etc. for these agents may cause discoloration.

In regard to contact cleaner

Do not use contact cleaners because it could cause a malfunction. Be specially careful not to use contact cleaners containing oil, for they may deform the plastic component.
