OWNER’S MANUAL

NS-4HX

Thank you for selecting this YAMAHA NS-4HX speaker system.

PRECAUTIONS

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.

● 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.

Speaker System

● Placing the speakers on the same shelf or rack as the
turntable can result in feedback.

● Never put a hand or a foreign object into the port located
on the rear of the speaker as this might cause personal
injury and/or damage to the speaker.

● When moving the speaker, do not hold the port as it
might cause personal injury and/or damage to the
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
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.

PLACING THE SPEAKERS

Place the speakers on a sturdy, vibration-free surface, on a
well-built stand.

■ 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.

Note
These speakers feature a magnetically shielded design,
but there is still a chance that placing them too close to
a TV set might impair picture color. Should this happen,
move the speakers away from the TV set.

■ CONNECTIONS

• Connect the screw-type input terminals at the rear of the

speakers to the speaker output terminals of the amplifier
(or receiver) with the speaker cable.

• Connect the (+) terminals on the amplifier (or receiver)

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.

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.
