Installation
Howling
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 charac-
teristics are richest when the subwoofer is installed in a corner
or near a wall. Since the low-bass component in music is usu-
ally monaural, only one subwoofer is necessary to obtain a
sufficient stereo effect when used in combination with a ste-
reo music system.
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
Far from the wall
If the Subwoofer is installed too close to aTV, color irregulari-
ties 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 theTV picture may be improved
by self-demagnetization of theTV set. If the color irregularities
still persist, move the Subwoofer farther away from theTV.

8 AUTO SHUTOFF switch
The phase relation between the subwoofer and front speakers
varies according to the distances, and the subwoofers setup
location. Set the phase switch to NOR. (normal phase) or REV
(reversed phase) so as to get the best bass sound at the loca-
tion at which you normally listen.
Use this switch to set the automatic shutoff feature ON or
OFF. If you set this ON, the subwoofer will automatically enter
standby mode if it does not receive a signal from the receiver
for a period of 30 minutes. The subwoofer will automatically
resume normal power when output from the receiver resumes.

Caution concerning operation
7 STANDBY/ON indicator
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.
Comes on to indicate that power is being supplied. Lights up
GREEN during normal operation; lights up RED if the subwoofer
has been switched into standby mode by the AUTO SHUTOFF
feature.
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.
Standby mode
While the standby indicator is lit, a small amount of power is
supplied to the system to back up the memory. This is called
standby mode.
2. When operating the amplifier switches or when placing
the stylus on an analog record, set the amplifier volume to
its minimum level.
The power in this equipment will not be completely cut off
from the AC wall outlet when the main switch is turned OFF.
