the internal parts are touched accidentally, a serious
electric shock might occur.
3. CAUTION – Polarization – This appliance may
be equipped with a polarized alternating-current line
plug (a plug having one blade wider than the other). This
plug will fit into the power outlet only one way. This is
a safety feature. If you are unable to insert the plug fully
into the outlet, try reversing the plug. If the plug should
still fail to fit, contact your electrician to replace your
obsolete outlet. Do not defeat the safety purpose of the
polarized plug.

18. Power lines – An outside antenna system should not
be located in the vicinity of overhead power lines or
other electric light or power circuits, or where it can fall
into such power lines or circuits. When installing an

recommended by the appliance manufacturer as they
may cause hazards.
17. Outdoor antenna grounding – If an outside
antenna is connected to the appliance, be sure
the antenna system is grounded so as to provide
some protection against voltage surges and built
up static charges. Article 810 of the National
22. Replacement parts – When replacement parts are
required, be sure the service technician has used
replacement parts specified by the manufacturer or
have the same characteristics as the original parts.
Unauthorized substitutions may result in fire, electric
shock, or other hazards.
Electrical Code
ANSI/NFPA 70, provides
information with respect to proper grounding of
the mast and supporting structure, grounding of
the lead-in wire to an antenna discharge unit, size
of grounding conductors, location of antenna
discharge unit, connection to grounding
electrodes, and requirements for the grounding
electrode. See Figure.

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.

1 PHASE switch
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.

4 LINE INPUT (R, L/MONO) terminal
Use to connect to the corresponding SUBWOOFER PRE OUT
jacks on your receiver. If your receiver has only one
SUBWOOFER PRE OUT jack, make the connection using the
L/MONO jack.
5 LINE OUTPUT (R, L) terminal
These jacks relay the signals received at the corresponding
LINE INPUT jacks.
6 POWER switch
Switches the power ON and OFF.
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.
