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.

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 counterclockwise). 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.

Caution

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

L eave a distance of more than 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.

B e sure to install the Subwoofer vertically.

Vertical installation

Connections

Before connection:

Set the POWER switches of the amplifier and Subwoofer to OFF. If they are connected with the POWER switch(es) left ON, one or both components may be damaged.

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.

① POWER ON indicator
②LINE INPUT jack (RCA-type pin-plug)

This jack is used to connect the subwoofer Pre-Out jack of the amplifier.

③ VOLUME control knob

Adjusts the volume level of the output of the Subwoofer. Rotating the knob clockwise increases the volume level, and rotating the knob counterclockwise decreases the volume level.

④ POWER switch

Switches the power ON and OFF.

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:

1. 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.
2. When operating the amplifier switches or when placing the stylus on an analog record, set the amplifier volume to its minimum level.
