Thank you for selecting this YAMAHA NS-120 speaker system.
PRECAUTIONS
Read these precautions carefully before using your 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. To clean, wipe with a dry,
soft cloth.
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.
●
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 speaker where it is liable to be knocked
over or struck by falling objects. Stable placement will also
ensure better sound performance.
●
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.
Use the stands included with the speakers to increase
stability:
●
Stands
Be sure to use the stands regardless of where the speakers
are positioned. Attaching the stands included with the
speakers 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 speakers will not
fall over.
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.).

HOW TO USE THE ACCESSORIES INCLUDED WITH THE SPEAKERS
English
■ Attaching the stand
Screw (6 mm) x 4
Stand x 4
When positioning the speakers, be sure to use the stand to
increase stability.
Use the 8 specified holes located on the base of the speaker.
Procedure:
Put the 6 mm screw through the larger hole on the stand,
➀
and attach to the speaker at one of the outside holes on
the base of the speaker. At this time, attach the stand to
the speaker so that it can still be moved slightly.
Put the 4 mm wood screw through the smaller hole on the
➁
stand, and screw it into the inside hole on the base of the
speaker.
When both screws have been attached, tighten both of the
➂
screws so that the stand is firmly in place.
Be sure to check that the stand is firmly attached.
Attach the pads to the bottom of the end portion of the
➃
stand.
Attach the other stands in the same manner and confirm
➄
that all 4 stands have been firmly attached.
Place the speaker in the desired location.
➅
Wood screw
(4 mm) x 4
Pad x 4
■ Attaching the spike
Spike x 4
When setting up the speakers on a thick carpet, use the spikes
instead of the stand. With 4 points set in place to achieve
increased stability and improvements in sound quality.
Procedure:
Set the nut close to the tip of the spike and screw them
➀
into the bottom of the speaker at each of the four specified
holes.
Place the speaker in the desired location in an upright
➁
position and adjust the length of the spike to match the
depth of the carpet.
When adjustment is complete, twist the nut up to the base
➂
of the speaker firmly.
Notes
●
The tips of the spikes may scratch or otherwise damage
the flooring. Please be careful when positioning the
speakers.
●
If force is applied to the side of the speaker, it may fall
and damage the speaker or cause personal injury.
Please be careful.

■ Using as 2ch stereo speakers
Better stereo images will be obtained when the speakers are
slightly angled in towards the listeners.
■ Using as main 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.

■ Connections
●
Connect the screw-type input terminals at the rear of the
speakers to the speaker output terminals of your amplifier
with the speaker cables.
●
Connect the (+) terminals on both the amplifier and 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 (marked L) terminals of your
amplifier, and another speaker to the right (marked 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.
Procedure:
Loosen the terminal knob.
➀
Remove approx. 10 mm insulation from the speaker cable
➁
and insert the bare wire end properly into the terminal hole.
Tighten the knob.
➂
Test the security of the connection by tugging lightly on the
➃
cable at the terminal.
Note
Do not let the bare speaker wires touch each other as this
could damage the speaker and/or the amplifier.
