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.
PLACING THE SPEAKER
Place the speaker on top of the TV or on the floor
under the TV or inside the TV rack so that it is stabilized.
When placing the speaker on top of the TV, to prevent the speaker from falling down, put the provided
velcro strips at two points on both bottom of the
speaker and top of the TV.

Notes
• Do not place the speaker on top of the TV
whose area is smaller than the bottom area of
the speaker. If placed, the speaker may drop out
causing an injury to you.
• Though this speaker is a magnetic shielding
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.

CONNECTION TO
YOUR AMPLIFIER
BEFORE MAKING CONNECTIONS, MAKE SURE
THAT THE AMPLIFIER IS SWITCHED OFF.
■ CONNECTIONS
● Connect the screw-type input terminals at the rear
of the speaker 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. If 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.
