Yamaha NS-100 User manual

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 speakers on the same shelf or rack as the turntable
can result in feedback.
●Secure placement or installation is the owner’s responsibility.
YAMAHAshall not be liable for any accident caused by improper
placement or installation of the speaker.

Thank you for selecting thisYAMAHA NS-100 speaker system.
PRECAUTIONS
PLACINGTHE 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.

REMOVINGTHE 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 inside surface of the cover with the four
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.

■Connections
●Connect the screw-type input terminals at the rear of the
speakers to the speaker output terminals of your amplifier with
the speaker cables.
●Connect the (+) terminals on both the amplifier 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.
Procedure:
➀Loosen the terminal knob.
➁Remove approx. 10 mm (3/8”) insulation from the speaker
cable and insert the bare wire end properly into the terminal
hole.
➂Tighten the knob.
➃Test the security of the connection by tugging lightly on the
cable at the terminal.
Note
Do not let the bare speaker wires touch each other as this
could damage the speaker and/or the amplifier.
Bi-Wiring Connections
This speaker system is capable of bi-wiring connections. To
connect the speakers to the output terminals of the amplifier, 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-wiring 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.
Note
For bi-wiring connections, use the same type of cable for both
the woofer and tweeter, making sure to match the polarity.
