Thank you for selecting this Yamaha speaker system.
PRECAUTIONS
Read these precautions carefully before using your speakers.
● Any time you notice distortion, reduce the volume of your
amplifier. Never allow your amplifier to be driven into “clip-
ping”. Otherwise the speakers may be damaged.
● When using an amplifier with a rated output power higher
than the nominal input power of the speakers, care should be
taken never to exceed the speakers’ maximum input.
● Do not attempt to clean the cabinets with chemical solvents
as this might damage the finish. Use a dry, soft cloth.
● To prevent the cabinets from warping or discoloring, do not
place the speakers where they will be exposed to direct sun-
light or excessive humidity.
● Do not place the speakers where they are liable to be
knocked over or struck by falling objects. Stable placement will
also ensure better sound performance.
● Do not place the speakers on the same shelf or rack as the
turntable.The vibration of the speakers might cause the feed-
back.
● Secure placement or installation is the owner’s responsi-
bility.
YAMAHA shall not be liable for any accident caused by
improper placement or installation of the speakers.
PRECAUTIONS WHEN POSITIONING THE SPEAKERS
The speaker is constructed with the majority of the weight locat-
ed 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 phe-
nomena 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 speakers to increase sta-
bility:
Be sure to use the stands regardless of where the speakers are
positioned. Attaching the stands included with the speakers rein-
forces the base of the speaker not to fall over.
Please be cautioned that even though the stands are connect-
ed, this does not guarantee that the speakers will not fall over.

BEFORE MAKING CONNECTIONS, MAKE SURE THAT THE
AMPLIFIER IS SWITCHED OFF.
■ CONNECTIONS
● Connect the screw-type input terminals at the rear of the
speakers to the speaker output terminals of your amplifier with
the provided speaker cords.
● One side of the speaker cord is red and the other side is
black. Connect the (+) terminals on both the amplifier and the
speakers using this red side. Connect the (–) terminals on
both components using the black side of the cord.
● Connect one speaker to the left (marked L) terminals of your
amplifier, and another speaker to the right (marked R) termi-
nals, making sure not to reverse the polarity (+, –). If one
speaker is connected with reversed polarity, the sound will be
unnatural and lack bass.
Procedure:
1 Loosen the terminal knob.
2 Insert the bare speaker wire end properly into the terminal
hole. [Remove approx. 10 mm (3/8”) insulation from the
speaker cord.]
3 Tighten the knob.
4 Test the security of the connection by pulling lightly the cord
at the terminal.
Note
Do not let the bare speaker wires touch each other as this
could damage the speakers or the amplifier, or both of
them.

Amplifier
● Place the speakers on a sturdy vibration-free surface. If you
cannot obtain good bass quality when the speakers are placed
directly on the floor, insert a block etc. between the speakers
and the floor.
● Better stereo images will be obtained when the speakers are
slightly angled in towards the listeners.
Note
Bacause these speakers are not a magnetically shielded
type, there may be some influence on a TV picture depend-
ing on the type of TV or the placement of the speakers. In
such a case, place the speakers apart from the TV.
PLACING THE SPEAKERS
When placing the speakers, be sure to use the stands to
increase stability.
Use the 8 specified holes located on the base of the speaker.
Procedure:
1 Put a screw through the inside hole on the stand, and screw
it into the speaker at one of the outside holes on the base of
the speaker.
At this time, screw it untightly so that the stand can still be
moved.
2 Put another screw through the outside hole on the stand, and
screw it into the inside hole on the base of the speaker.
3 Tighten both of the screws firmly.
4 Attach a leg to the bottom of the end portion of the stand.
5 Attach the other stands to the other corners of the base of
the speaker in the same way and confirm that all 4 stands
have been firmly attached.
Note
Be carefull not to apply force to the side of the speaker, oth-
erwise the speaker may fall causing damage to the speaker
or personal injury.
