• To assure the finest performance, please read this manual
carefully. Keep it in a safe place for future reference.
• Install the speaker 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 speaker to rain or water.
• To prevent the enclosure from warping or discoloring, do not
place the speaker where it will be exposed to direct sunlight
or excessive humidity.
• Do not place the following objects on the speaker:
Glass, china, etc.
- If glass etc. falls by vibrations and breaks, it may cause
personal injury.
A burning candle etc.
- If the candle falls by vibrations, it may cause fire and
personal injury.
A vessel with water in it
- If the vessel falls by vibrations and water spills, it may
cause damage to the speaker, and/or you may get an
electric shock.
• Do not place the speaker where foreign objects such as
water drips might fall. It might cause a fire, damage to the
speaker, and/or personal injury.
• Do not place the speaker where it is liable to be knocked
over or struck by falling objects. Stable placement will also
ensure better sound performance.
SPEAKER SYSTEM
• Placing the speaker on the same shelf or rack as the
turntable can result in feedback.
• Never put a hand or a foreign object into the port located on
the rear of the speaker as this might cause personal injury
and/or damage to the speaker.
• When moving the speaker, do not hold the port as it might
cause personal injury and/or damage to the speaker.
• Any time you note distortion, reduce the volume control on
your amplifier to a lower setting. Never allow your amplifier
to be driven into “clipping”. Otherwise the speaker may be
damaged.
• When using an amplifier with a rated output power higher
than the nominal input power of the speaker, care should be
taken never to exceed the speaker’s maximum input.
• Do not attempt to clean the speaker with chemical solvents
as this might damage the finish. Use a clean, dry cloth.
• Do not attempt to modify or fix the speaker. Contact
qualified Yamaha service personnel when any service is
needed. The cabinet should never be opened for any
reasons.
• As this unit is heavy, whenever it is moved, two people are
required to transport it safely.
• Secure placement or installation is the owner’s
responsibility. Yamaha shall not be liable for any
accident caused by improper placement or installation
of the speaker.
PRECAUTIONS WHEN POSITIONING THE SPEAKERS
The speaker is constructed with the majority of the weight
located in its upper portion, and is thus susceptible to falling
over if proper care is not taken to insure its stability. If the
speaker falls over, it may damage the speaker or be the cause
of injury (or even death) to persons and/or damage to personal
property.
For safe and proper use of the speaker:
• Position the speaker in a location that is solid, level, smooth,
and low (with respect to the floor).
• Do not push or apply pressure to the side of the speaker
when moving, or lean objects against the side of the
speaker.
• Do not sit on or set objects on top of the speaker.
Vibrations or jolts associated with earthquakes and other
phenomena or activities may cause the speaker to fall over.
For safety reasons, using commercially available products
that increase stability in the speaker is recommended (metal
fittings or chains, etc.).
Use the stands included with the speaker to increase
stability:
Be sure to use the stands regardless of where the speaker is
positioned. Attaching the stands included with the speaker
reinforces the base of the speaker not to fall over. Please be
cautioned that even though the stands are connected, this
does not guarantee that the speaker will not fall over.
• Place the speakers on a sturdy, vibration-free surface, or on
a well-built stand.

ATTACHING THE STANDS
When placing the speakers, be sure to use the stands to
increase stability.
Notes
• The provided stands are in two types. Two stands are
for the right side and others are for the left side. Attach
each stand to the proper position on the bottom of the
speaker by following the figure below.
• When attaching the stands to the speaker, have another
person support it.
• To attach the stands to the speaker, be sure to lay down
the speaker while the front is facing up. We recommend
using a blanket or cushion (thickness of 3 cm or more)
to raise the speaker from the floor.

PLACING THE SPEAKERS
English
■ Using as 2ch stereo speakers
Better stereo images will be obtained when the speakers are
slightly angled towards the listeners.
■ Using as front speakers in a multi
channel system
Position the speakers on both sides of the TV. The positioning
of speakers is important, because it controls the whole sound
quality of a multi channel system. Set up the speakers on the
basis of your listening position by following the owner’s
manual supplied with your amplifier.

Note
These speakers feature a magnetically shielded design,
but there is still a chance that placing them too close to a
TV set might impair picture color or buzzing noise. Should
this happen, move the speakers away from the TV set.

CONNECTING TO YOUR AMPLIFIER
■ Connections
Before making connection, make sure that the
amplifier is switched off.
• Connect the screw-type terminals at the rear of the
speakers to the speaker terminals on the amplifier with
a supplied speaker cable.
• Connect the + terminals on the amplifier and on the
speakers using one side of the cable. Connect the –
terminals on both components using the other side of
the cable.
• Connect one speaker to the left (L) terminals of your
amplifier, and another speaker to the right (R) terminals,
making sure not to reverse the polarity (+, –). If one
speaker is connected with reversed polarity, the sound
will be unnatural and lack bass.
How to connect
1 Loosen the knob.
2 Twist the exposed wires of the cable together.
