Installation

The Subwoofer is a virtually omnidirectional speaker, 50 it can be installed in almost any location. For example, the Subwoofer can be installed next to the component system (consisting of an amplifier, luner, cassetle 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 counter clock-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.

Connections

Before connection: –

1. Set the POWER switches of the amplifier and Subwoofer to OFF. If they are connected with the POWER switches left ON, one or both of them may be damaged.
   • If the amplifier is equipped with a Subwoofer Pre-Out jack

4. PHASE switch
   Switches the speaker sound phase to vary the tonal quality of the bass.

5. VOLUME CONTROL
   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.

Typical Control Positions

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.

Note:

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.
