* Please keep this manual in a safe place for future reference.
Always follow the basic precautions listed below to avoid the possibility of serious injury or even death from electrical
shock, short-circuiting, damages, ﬁre or other hazards. These precautions include, but are not limited to, the following:
•Do not open the device or attempt to disassemble the inter-
nal parts or modify them in any way. The device contains
no user-serviceable parts. If it should appear to be mal-
functioning, discontinue use immediately and have it
inspected by qualiﬁed Yamaha service personnel.
•Do not expose the device to rain, use it near water or in
damp or wet conditions, or place containers on it contain-
ing liquids which might spill into any openings.
Always follow the basic precautions listed below to avoid the possibility of physical injury to you or others, or damage
to the device or other property. These precautions include, but are not limited to, the following:
•If you use a stand, check the stand’s speciﬁcations and
make sure that it is sturdy enough to support the weight of
the speaker. You may need to limit the number of people
around the placed stand, in order to avoid toppling the
device or causing damage to the internal components.
•If you use speaker stands, be sure to keep the following
– Use the speaker stands with their legs fully opened.
–Place only one speaker on each speaker stand.
– Tighten fastening screws securely.
–Remove the speakers from the stands before moving
the stands or adjusting their height.
–Add weight such as sand bags around the stand legs to
prevent them from falling over.
– Use the stand at a maximum height of 140 cm.
•If you use a metal socket of the SW115V/SW118V sub-
woofer to allow mounting of a satellite speaker, use a pole
shorter than 90cm with an outer diameter of 35mm.
•When transporting or moving the device, always use two or
• Before moving the device, remove all connected cables.
•Do not expose the device to excessive dust or vibrations,
or extreme cold or heat (such as in direct sunlight, near a
heater) to prevent the possibility of panel disﬁguration or
damage to the internal components.
•Do not place the device in an unstable position where it
might accidentally fall over.
•Before connecting the device to other devices, turn off the
power for all devices. Before turning the power on or off for
all devices, set all volume levels to minimum.
•Use only speaker cables for connecting speakers to the
speaker jacks. Use of other types of cables may result in
•Be sure to observe the ampliﬁer’s rated load impedance
(see page 4), particularly when connecting speakers in
parallel. Connecting an impedance load outside the ampli-
ﬁer’s rated range can damage the ampliﬁer.
•Do not use the device for a long period of time at a high or
uncomfortable volume level, since this can cause perma-
nent hearing loss. If you experience any hearing loss or
ringing in the ears, consult a physician.
•Do not operate the device if the sound is distorting. Pro-
longed use in this condition could cause overheating and
result in ﬁre.
•Always turn AC power to the power ampliﬁer on last in any
audio system to avoid speaker damage. When turning
power off, the power ampliﬁer should be turned off ﬁrst for
the same reason.
