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.
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 cas-
sette 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 too close to a TV, color irregularities may
be observed on the TV screen. If such irregularities occur, switch the
power of the TV to OFF and then switch it ON again after waiting for
a period of 15 to 30 minutes. The influence of the Subwoofer on the
TV picture may be improved by self-demagnetization of the TV set. If
the color irregularities still persist, move the Subwoofer farther away
from the TV.

Interference in radio broadcasts
This unit employs digital circuitry to amplify signals with high effi-
ciency. As a result, when a radio receiver such as an audio receiver or
tuner is installed near this unit, the reception may be interfered with
by noise. In such a case, install this unit and radio receiver at a larger
distance.
¶ If the radio reception is still interfered with by noise even when the
power of this unit is switched off or the volume is minimized, the
interference is not due to this unit.
¶ When the indoor antenna of the audio receiver or tuner can be
installed apart from this unit, install the antenna as apart as possible
from this unit. Also distribute the antenna cable as apart as possible
from this unit.
