Read this before using the speakers.
To assure the finest performance, please read this manual
carefully. Keep it in a safe place for future reference.
Install the speakers 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 speakers to rain or water.
To prevent the enclosure from warping or discoloring, do
not place the speakers where they will be exposed to
direct sunlight or excessive humidity.
Do not place the following objects on the speakers:
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 speakers, and/or you may get an
electric shock.
Do not place the speakers where foreign objects such as
water drips might fall. It might cause a fire, damage to
the speakers, and/or personal injury.
PRECAUTIONS
Place the center speaker on the floor under the TV or inside
the TV rack so that it is stabilized. The center speaker
should be set in alignment with the center of the TV screen.
The positioning of the center speaker is important, because
it controls the whole sound quality of a multi channel
system. Set up the center speaker on the basis of your
listening position by following the owner’s manual supplied
with your amplifier.
IMPORTANT
Do not place the center speaker on top of the TV. If
placed, the speaker may fall and possibly cause
damage or personal injury.
Note
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. Should this happen,
move the speaker away from the TV set.

OWNER’S MANUAL
G R
Thank you for selecting this YAMAHA NS-C7HX speaker system.
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.
Placing the speakers 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
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 speakers with chemical solvents
as this might damage the finish. Use a clean, dry cloth.
Do not attempt to modify or fix the speakers. 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 speakers.

CONNECTIONS TO YOUR AMPLIFIER

NS-C7HX
This speaker system is capable of standard connections and bi-wired connections. 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 Insert the bare wire. [Remove the insulation coating at
the extremity of each speaker cable by twisting the
coating off.]
3 Tighten the knob and secure the cable.
Test the firmness of the connection by pulling lightly on
the cable at the terminal.
Note
Do not let the bare speaker wires touch each other as
this could damage the speaker or the amplifier, or both
of them.

When using a banana plug
<General model only>
1 Remove the cover by pulling it toward you.
2 Tighten the terminal knob.
3 Simply insert the banana plug into the terminal.
Bi-Wired Connections
This speaker system is capable of bi-wired connections. To
connect the speaker to the output terminals of the amplifier
(or receiver), two pairs of cables for each of woofer and
tweeter are used instead of standard connections. This type
of connection decreases the modulation distortion caused
by electric resistance of the cables and driving current of
the speakers. Consequently, purer sound quality can be
expected.
To utilize bi-wired connections, remove the short bars from
the terminals first, and then connect the woofer and tweeter
to the amplifier separately using two pairs of cables.
<Bi-wired connections>
Remove the short
bars before
connecting.

REMOVING THE FRONT COVER
The front cover is fastened to the enclosure at four points
and can be removed if desired. To remove the cover, hold
on to both sides and slowly pull straight away from the
speaker. To reattach, line up the four pegs on the speaker
with the four corresponding holes on the inside surface of
the cover and push gently.

When the cover is removed, take care not to touch the
speaker units with your hands or to exert excessive
force with tools.
