check the load impedance the ampliﬁer can drive. The nominal impedance of one CBR is eight ohms and the
total impedance of two parallel connected CBRs is four ohms. In this case, the ampliﬁer must be able to drive
less than four ohm load impedance.

• Do not place the device in an unstable position or fail
to secure it pr
operly in a potentially dangerous position
where it may fall even if the position is horizontal. The
device may accidentally fall over
, resulting in damage
• Do not use the speaker’
s handles for suspended
installation. Doing so can result in damage or injury
• Do not hold the bottom of the device when transpor
or moving it. In doing so, you may pinch your hands
under the device, and result in injury
• Do not place the device in a location where it may come
into contact with corrosive gases or salt air
. Doing so
may result in malfunction.
• Before moving the device, remove all connected cables.
• Always consult qualiﬁed Y
amaha service personnel if
the device installation requir
es construction work, and
make sure to observe the following pr
– Choose mounting hardware and an installation
location that can support the weight of the device.
– Avoid locations that are exposed to constant vibration.
– Use the required tools to install the device.
– Inspect the device periodically
• 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. Use of other types of cables
may result in ﬁr
• Do not inser
t your ﬁngers or hands in any gaps or
openings on the device.
• Do not rest your weight on the device or place heavy
objects on it, and avoid use excessive force on the
buttons, switches or connectors.
• Do not use the speakers for a long period of time at
a high or uncomfortable volume level, since this can
cause permanent 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 distor

• When choosing a power ampliﬁer for use with this
device, make sure that the output power of the ampliﬁer
is lower than the power capacity of this device. If
the output power is higher than the power capacity
malfunction or ﬁre may occur
• Do not input excessively loud signals that may result in
clipping in the ampliﬁer or cause the following:
– Feedback, when using a microphone
– Continuous and extremely loud sound from a musical
– Continuous and extremely loud distorted sound
– Noise caused by plugging/unplugging the cable while
the ampliﬁer is turned on
Even if the output power of the ampliﬁer is lower than
the power capacity of this device (program), damage to
the device, malfunction or ﬁre may occur
amaha cannot be held responsible for damage caused
by improper use or modiﬁcations to the device, or data
that is lost or destroyed.
o avoid the possibility of malfunction/damage to the
product, damage to data, or damage to other pr
follow the notices below
Handling and Maintenance
• Do not expose the device to excessive dust or vibration,
or extreme cold or heat (such as in dir
ect sunlight, near
, or in a car during the day), in order to prevent
the possibility of panel disﬁguration, unstable operation,
or damage to the internal components.
• Do not place vinyl, plastic or rubber objects on the
device, since this might discolor the panel.
• When cleaning the device, use a dr
y and soft cloth.
Do not use paint thinners, solvents, cleaning ﬂuids, or
chemical-impregnated wiping cloths.
• Condensation can occur in the device due to rapid,
drastic changes in ambient temperature—when the
device is moved from one location to another
, or air
conditioning is turned on or off, for example. Using
the device while condensation is present can cause
damage. If there is r
eason to believe that condensation
might have occurred, leave the device for several hours
until the condensation has completely dried out.
• When tur
ning on the AC power in your audio system,
always turn on the power ampliﬁer LAST
, to avoid
speaker damage. When turning the power off, the
power ampliﬁer should be turned off FIRST for the same
• Be sure to observe the power ampliﬁer’
s rated load
impedance, particularly when connecting speakers in
parallel. Connecting an impedance load outside the
s rated range can damage the power ampliﬁer .
• Protective Circuit
All full-range loudspeakers are ﬁtted with a self-r
poly switch that protects the high-fr
equency driver from
damage caused by excessive power
. If a loudspeaker
cabinet loses high-frequency output, immediately
remove power fr
om the power ampliﬁer and wait for two
to three minutes. This should be long enough to allow
the poly switch to reset. Reapply power and check
mance of the high-frequency driver befor e
continuing, with the power reduced to a level that does
not cause the poly switch to interrupt the signal.
• Air blowing out of the bass reﬂex ports is nor
often occurs when the speaker is handling program
material with heavy bass content.
• Use only Neutrik speakON plugs (NL4) for connecting

Before doing any installation or construction work, consult with your Y amaha dealer .
For optimum safety , the installation should be checked thoroughly at regular intervals. Some fittings may deteriorate over
extended periods of time due to wear and/or corrosion.
When choosing the installation location, suspension wire and mounting har dware, make sure all ar e strong enough to
support the weight of the speaker
Make sure to take measur es to prevent the speaker from falling down in the event of a installation failur e.
When installing the safety wire to the wall, install it higher than the wir e’ s attachment point on the speaker , with as little
slack as possible. If the wire is too long, and the speaker happens to fall, the wir
e may snap as a result of too much strain.
