Installation
CAUTION
To assure ventilation, observe the following points when in-
stalling the unit.
• Leave a distance of more than 10 cm between the Subwoof-
er 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.
Howling
If the Subwoofer is installed near an analog record turntable, a
howling sound may be generated. If this occurs, place the Sub-
woofer farther away from the turntable or reduce the Subwoof-
er 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 La-
serdisc 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 Sub-
woofer from the TV until its reception becomes normal.
