Natural Sound Bass-Reflex Effect Speaker System

Thank you for selecting this Yamaha NS-E103 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 is exposed to direct sunlight or
excessive humidity.

CONNECTION TO YOUR AMPLIFIER

BEFORE MAKING CONNECTIONS, MAKE SURE THAT THE
AMPLIFIER IS SWITCHED OFF.

■ CONNECTIONS

● Connect the push-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 marked with a gray line.
Connect the (+) terminals on both the amplifier and the
speakers using this gray-marked side. Connect the (–)
terminals on both components using the unmarked 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, being sure not to reverse the polarity (+, –). If one
speaker is connected with reversed polarity, the sound will be
unnatural and lack bass.

Procedures:

➀ Press the tab on the terminal down, as shown in the figure.
➁ Insert the bare wire end properly into the terminal hole.

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

➂ Remove your finger from the tab to allow it to lock snugly on

the cable’s wire end.

➃ Check the connection by lightly pulling the cable at the

terminal.

● 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.

● As some speaker contain strong magnets, avoid placing
watches, magnetic tapes, etc. near them. Also, placing
speaker near a TV set may impair picture color. If this
happens, move the speakers away from the TV set .

● 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.

WARNING:

* Each speaker weighs 1.4 kg (3 lbs. 1 oz.). Do not mount them

on thin plywood or soft wall surface material, as the screws
may come out of the flimsy surface, causing the speakers to
fall down and be damaged, or result in personal injury.

* Do not fasten the speakers to walls with nails, adhesives, or

other unsound hardware. Long-term use and vibrations may
cause them to fall down.

* To avoid accidents resulting from tripping over loose speaker

cables, fix them to the wall.
