Thank you for selecting this YAMAHA subwoofer system.
CAUTION: READ THIS BEFORE OPERATING YOUR UNIT.
1. To assure the finest performance, please read this manual
carefully. Keep it in a safe place for future reference.
2. Install this unit in a cool, dry, clean place, away from
windows, heat sources, sources of excessive vibration,
dust, moisture and cold. Avoid sources of humming
(transformers, motors). To prevent fire or electrical shock,
do not expose the unit to rain or water.
3. Never open the cabinet. If something drops into the set,
contact your dealer.
4. Do not use force on switches, controls or connection wires.
When moving the unit, first disconnect the power plug and
the wires connected to other equipment. Never pull the
wire itself.
5. Do not attempt to clean the unit with chemical solvents;
this might damage the finish. Use a clean, dry cloth.
6. Be sure to read the “TROUBLESHOOTING” section
regarding common operating errors before concluding that
the unit is faulty.
7. When not planning to use this unit for long periods of time
(i.e., vacation, etc.), disconnect the AC power plug from
the wall outlet.
8. To prevent lightning damage, disconnect the AC power
plug when there is an electrical storm.
9. Since this unit has a built-in power amplifier, heat will
radiate from the rear panel. Therefore, place the unit apart
from the walls, allowing enough space above, behind and
on the both sides of the unit to prevent fire and damage.
Also, do not position with the rear panel facing down on
the floor or other surface.
<For U.K. and Europe models only>
Be sure to allow a space of at least 20 cm above, behind
and on the both sides of the unit.
10.Super-bass frequencies reproduced by this unit may cause
a turntable to generate a howling sound. In such a case,
move this unit away from the turntable.
11. Vibration generated by super-bass frequencies may cause
images on a TV to be distorted. In such a case, move this
unit away from the TV set.
12.This unit features a magnetically shielded design, but there
is still a chance that placing it too close to a TV set might
impair picture color. Should this happen, move this unit
away from the TV set.
13.If you hear distortion (i.e., unnatural, intermittent “rapping”
or “hammering” sounds) coming from this unit, reduce the
volume level. Extremely loud playing of a movie
soundtrack’s low frequency, bass-heavy sounds or
similarly loud popular music passages can damage this
speaker system.
14. Voltage Selector (General and China Models only)
The voltage selector on the rear panel of this unit must
be set for your local main voltage BEFORE plugging
into the AC main supply.
Voltages are AC 110/120/220/240V, 50/60 Hz.
IMPORTANT
Please record the serial number of this unit in the space
below.
Serial No.:
The serial number is located on the rear of the unit.
Retain this Owner’s Manual in a safe place for future
reference.
15.Secure placement or installation is the owner’s
responsibility.
YAMAHA shall not be liable for any accident caused
by improper placement or installation of speakers.
For U.K. customers
If the socket outlets in the home are not suitable for the plug
supplied with this appliance, it should be cut off and an
appropriate 3 pin plug fitted. For details, refer to the
instructions described below.
Note: The plug severed from the mains lead must be
destroyed, as a plug with bared flexible cord is hazardous if
engaged in a live socket outlet.
SPECIAL INSTRUCTIONS FOR U.K. MODEL
IMPORTANT
THE WIRES IN THE MAINS LEAD ARE COLOURED IN
ACCORDANCE WITH THE FOLLOWING CODE:
Blue: NEUTRAL
Brown: LIVE
As the colours of the wires in the mains lead of this
apparatus may not correspond with the coloured markings
identifying the terminals in your plug, proceed as follows:
The wire which is coloured BLUE must be connected to the
terminal which is marked with the letter N or coloured
BLACK. The wire which is coloured BROWN must be
connected to the terminal which is marked with the letter L or
coloured RED. Making sure that neither core is connected to
the earth terminal of the three pin plug.
FOR CANADIAN CUSTOMERS
TO PREVENT ELECTRIC SHOCK, MATCH WIDE BLADE
OF PLUG TO WIDE SLOT AND FULLY INSERT.
THIS CLASS B DIGITAL APPARATUS COMPLIES WITH
CANADIAN ICES-003.
WARNING
TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK,
DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE.
FEATURES
• This subwoofer system employs Advanced YAMAHA Active
Servo Technology which YAMAHA has developed for
reproducing higher quality super-bass sound. (Refer to page
10 for details on Advanced YAMAHA Active Servo
Technology .) This super-bass sound adds a more realistic,
theater-in-the-home effect to your stereo system.
• This unit can be added easily to your existing audio system
by connecting to either the speaker terminals or the line
output (pin jack) terminals of the amplifier.
PLACEMENT
One subwoofer will have a good effect on your audio system,
however, the use of two subwoofers is recommended to obtain
more presence.
If using one subwoofer, it is recommended to place it on the
outside of either the right or the left main speaker. (See fig. Å.)
If using two subwoofers, it is recommended to place them on
the outside of each main speaker. (See fig. ı.) The placement
shown in fig. Ç is also possible, however, if the subwoofer
system is placed directly facing the wall, the bass effect may
die because the sound from it and the sound reflected by the
wall may cancel. To prevent this, face the subwoofer system
obliquely to the wall as in fig. Å or ı.
Note
There may be a case that you cannot obtain enough super-
bass sounds from this unit when listening at the middle of the
room. This is because “standing waves” have developed
between two parallel walls and the bass sounds are canceled.
In such a case, face the unit obliquely to the wall. It also may
be necessary to break up the parallel surfaces by placing
bookshelves etc. along the walls.
