OWNER’S MANUAL

NS-C325

Thank you for selecting this YAMAHA NS-C325 speaker system.

PRECAUTIONS

Read this before using the speaker.

•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.

Speaker System

• 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.

• Placing the speaker on the same shelf or rack as the
turntable can result in feedback.

• 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.

• 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.

PLACING THE SPEAKER

Place the speaker on TV whose top is flat or on the floor under the TV or inside the TV rack so that it is stabilized.
When placing the speaker on top of the TV, to prevent the speaker from falling down, put the provided fasteners at four points
on the bottom of the speaker and the top of the TV.

Notes

•

Do not place the speaker on top of the TV whose area is
smaller than the bottom area of the speaker. If placed,
the speaker may drop out causing an injury to you.

• Do not place the speaker on top of the TV with an
inclination.

• Do not touch the adhesive surface after peeling off
the seal as this will weaken its adhesive strength.

•

Thoroughly wipe clean the surface where the fastener is to be
applied. Note that adhesive strength is weakened if the surface is
dirty, oily or wet and that this may cause the center speaker to drop.

•

This speaker features a magnetically shielded design, but
there is still a chance that placing it too close to a TV set
might impair picture color or create a buzzing noise. Should
this happen, move the speaker away from the TV set.

CONNECTIONS TO YOUR AMPLIFIER

Before making connections, make sure that the amplifier is switched off.

■ CONNECTIONS

• Connect the screw-type input terminals at the rear of the
speaker to the speaker output terminals of the amplifier
(or receiver) with the speaker cable.

• Connect the (+) terminals on the amplifier (or receiver)
and the speaker using one side of the cable. Connect the
(–) terminals on both components using the other side of
the cable.

• Connect the speaker to the center terminals of your
amplifier, making sure not to reverse the polarity (+, –). If
the speaker is connected with reversed polarity, the
sound will be unnatural and lack bass.

How to connect:

1 Loosen the knob.
2 Remove the insulation coating at the extremity of each

speaker cable by twisting the coating off.

3 Insert the bare wire.
4 Tighten the knob and secure the cables.

Test the firmness of the connection by pulling lightly on
the cables at the terminal.
