WARNING
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
• This device contains no user-serviceable parts. Do not
open the device or attempt to disassemble the internal
parts or modify them in any way. If it should appear
to be malfunctioning, discontinue use immediately
and have it inspected by qualified Yamaha service
personnel.
Fire warning
• Do not put burning items, such as candles, on the unit.
A burning item may fall over and cause a fire.
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:
Location
• Do not place the device in an unstable position or fail
to secure it properly in a potentially dangerous position
where it may fall even if the position is horizontal. The
device may accidentally fall over, resulting in damage
and/or injury.
• 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 transporting
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 Yamaha service personnel if
the device installation requires construction work, and
make sure to observe the following precautions.
– 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.
Connections
• 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 fire.
Handling caution
• Do not insert 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 distorting.
Prolonged use in this condition could cause overheating
and result in fire.
PRECAUTIONS
CAUTION
• 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
instrument, etc.
– 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.
Yamaha cannot be held responsible for damage caused
by improper use or modifications to the device, or data
that is lost or destroyed.
NOTICE
To avoid the possibility of malfunction/damage to the
product, damage to data, or damage to other property,
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 direct sunlight, near
a heater, 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 dry 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 reason to believe that condensation
might have occurred, leave the device for several hours
until the condensation has completely dried out.
• When turning 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
reason.
• Be sure to observe the power amplifier's rated load
impedance, particularly when connecting speakers in
parallel. Connecting an impedance load outside the
amplifier's rated range can damage the power amplifier.
• Protective Circuit
All full-range loudspeakers are fitted with a self-resetting
poly switch that protects the high-frequency driver from
damage caused by excessive power. If a loudspeaker
cabinet loses high-frequency output, immediately
remove power from 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
the performance of the high-frequency driver before
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 normal, and
often occurs when the speaker is handling program
material with heavy bass content.
Connectors
• Use only Neutrik speakON plugs (NL4) for connecting
speakON connectors.
