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.
