not fall and liquid is not spilled into the enclosure  
through openings. If a metal objects, such as a hair pin  
or a needle, comes into contact with the inside of this  
appliance, a dangerous electric shock may result. For  
families with children, never permit children to put  
anything, especially metal, inside this appliance.  
2. Power-cord protection – Power-supply cords should  
be routed so that they are not likely to be walked on or  
pinched by items placed upon or against them, pay  
particular attention to cords at plugs, convenience  
receptacles, and the point where they exit from the  
appliance.  
Never pull or stretch the cord.  
9. Enclosure removal – Never remove the enclosure. If  
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.  
10. MagneticfieldsKeeptheapplianceawayfromsources  
of magnetic fields such as TV sets, speaker systems,  
radios, motorized toys or magnetized objects.

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  
outside antenna system, extreme care should be taken  
to keep from touching such power lines or circuits as  
contact with them might be fatal.  
15. Damage requiring service – The appliance should  
be serviced by qualified service personnel when:  
A. The power-supply cord or the plug has been  
damaged.

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.  
23. Safety check – Upon completion of any service or  
repairs to this appliance, ask the service technician to

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.

Near the wall  
B
Leave a distance of more than 10  
cm between the heat sink of the  
Subwoofer and the surrounding  
wall(s).  
C
Use special care not to cover the  
heat sink with a curtain, etc. when  
installing.

Frequency  
Be sure to install the Subwoofer vertically.  
Connections  
Before connection:  
Set the POWER switches of the amplifier and Subwoofer to OFF. If they are connected with the POWER switch(es) left  
ON, one or both components may be damaged.

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.

3 VOLUME knob  
Adjusts the volume level of the output of the Subwoofer. Ro-  
tating the knob clockwise increases the volume level, and ro-  
tating the knob counterclockwise decreases the volume level.

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 amplifiers  
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.
