Natural Sound Effect Speaker System

PRECAUTIONS

This model is designed to be used as an effect
speaker

system.

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.

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

● 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.

■ Mounting the speakers on a wall

The speakers can be mounted on a wall by using the holes
provided on the speakers’ back panels.

Fasten screws into a firm wall or wall support as shown in
the diagram, and hang the holes on the protruding screws.

WARNING:

* Each speaker weighs 1.7 kg (3 lbs. 12 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 wall 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.

■ 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 by a blue line.
Connect the (+) terminals on both the amplifier and the
speakers using this blue-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, 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 Press the tab on the terminal down, as shown in the

figure.

➁ Insert the bare speaker wire end properly into the

terminal hole. [Remove approx. 5 mm (1/4”) 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 Test 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.
