Thank you for selecting this Yamaha NS-70 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.

● 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.

● Placing the speaker on the same shelf or rack as the turntable

can result in feedback.

● 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.

BEFORE MAKING CONNECTIONS, MAKE SURE THAT THE

AMPLIFIER IS SWITCHED OFF.

■ CONNECTIONS

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

speakers to the speaker output terminals of your amplifier with

the provided speaker cables.

● One side of the speaker cable is red and the other side is

black. Connect the (+) terminals on both the amplifier and the

speakers using this red side. Connect the (–) terminals on both

components using the black 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.

Procedures:

➀ Loosen the terminal knob.

➁ Insert the bare wire end properly into the terminal hole.

[Remove approx. 10 mm (3/8”) insulation from the speaker

cable.]

➂ Tighten the knob.

➃ Test the security of the connection by tugging lightly on the

cable at the terminal.

* Banana Plug connections

are also possible. First

tighten the terminal knobs,

and then insert the

Banana Plug connector

into the corresponding

terminal hole.

Note

Do not let the bare speaker wires touch each other as this

could damage the speaker and/or the amplifier.

PLACING THE SPEAKER

● Place the speakers on a sturdy, vibration-free surface. If you

cannot obtain good bass quality when the speakers are placed

directly on the floor, insert a block etc. between the speakers

and the floor.

● Better stereo images will be obtained when the speakers are

slightly angled in towards the listeners.

Note

Bacause this speaker is not a magnetically shielded type,

there may be some influence on a TV picture depending on

the type of TV or the placement of the speaker. In such a

case, place the speaker apart from the TV so that there is no

influence on TV picture.

REMOVING THE FRONT COVER

The front cover is fastened to the enclosure at six 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 six pegs on the inside surface of the cover

with the six corresponding holes on the speaker and push

gently.

Note

When the cover is removed, take care not to touch the

speaker units with your hands or to exert excessive force

with tools.
