WARNING
Always follow the basic precautions listed below to avoid
the possibility of serious injury or even death from electrical
shock, short-circuiting, damages, īšœre or other hazards. These
precautions include, but are not limited to, the following:
Power supply/power cord
ā€¢ Do not place the power cord near heat sources such as heaters
or radiators, and do not excessively bend or otherwise damage
the cord, place heavy objects on it, or place it in a position
where anyone could walk on, trip over, or roll anything over it.
ā€¢ Only use the voltage speciļ¬ed as correct for the device. The
required voltage is printed on the name plate of the device.
ā€¢ Use only the supplied power cord. If you intend to use the
device in an area other than in the one you purchased, the
included power cord may not be compatible. Please check
with your Yamaha dealer.
ā€¢ Check the electric plug periodically and remove any dirt or
dust which may have accumulated on it.
ā€¢ When setting up the device, make sure that the AC outlet you
are using is easily accessible. If some trouble or malfunction
occurs, immediately turn off the power switch and disconnect
the plug from the outlet. Even when the power switch is turned
off, as long as the power cord is not unplugged from the wall
AC outlet, the device will not be disconnected from the power
source.
ā€¢ Remove the electric plug from the outlet when the device is not
to be used for extended periods of time, or during electrical
storms.
ā€¢ Be sure to connect to an appropriate outlet with a protective
grounding connection.

ā€¢ 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 qualiļ¬ed Yamaha service personnel.
Water warning
ā€¢ Do not expose the device to rain, use it near water or in damp
or wet conditions, or place on it any containers (such as vases,
bottles or glasses) containing liquids which might spill into any
openings. If any liquid such as water seeps into the device,
turn off the power immediately and unplug the power cord from
the AC outlet. Then have the device inspected by qualiļ¬ed
Yamaha service personnel.
ā€¢ Never insert or remove an electric plug with wet hands.
Hearing loss
ā€¢ Avoid setting volume controls to their maximum. Depending on
the condition of the connected devices, doing so may result
in feedback that can cause hearing loss and damage the
speakers.
ā€¢ Do not use 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.
ā€¢ When turning on the AC power in your audio system, always
turn on the device LAST, to avoid hearing loss and speaker
damage. When turning the power off, the device should be
turned off FIRST for the same reason.

ā€¢ Do not place any burning items or open ļ¬‚ames near the
device, since they may cause a ļ¬re.
If you notice any abnormality
ā€¢ If any of the following problems occur, immediately turn off the
power switch and disconnect the electric plug from the outlet.
ā€“ The power cord or plug becomes frayed or damaged.
ā€“ Unusual smells or smoke are emitted.
ā€“ Some object has been dropped into the device.
ā€“ There is a sudden loss of sound during use of the device.
ā€“ Cracks or other visible damage appear on the device.
Then have the device inspected or repaired by qualiļ¬ed
Yamaha service personnel.
ā€¢ If this device should be dropped or damaged, immediately turn off
the power switch, disconnect the electric plug from the outlet, and
have the device inspected by qualiļ¬ed Yamaha service personnel.
CAUTION
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:
Power supply/power cord
ā€¢ When removing the electric plug from the device or an outlet,
always hold the plug itself and not the cord. Pulling by the cord
can damage it.
Location
ā€¢ Do not place the device in an unstable position where it might
accidentally fall over.
ā€¢ Do not block the vents. This device has ventilation holes at the top/
sides/bottom to prevent the internal temperature from becoming
too high. In particular, do not place the device on its side or
upside down. Inadequate ventilation can result in overheating,
possibly causing damage to the device(s), or even ļ¬re.
ā€¢ When installing the device and you wish to dissipate heat on it:
ā€“ Do not cover it with any cloth.
ā€“ Do not install it on a carpet or rug.
ā€“ Make sure the top surface faces up; do not install on its
sides or upside down.
ā€“ Do not use the device in a conļ¬ned, poorly-ventilated
location.
Inadequate ventilation can result in overheating, possibly
causing damage to the device(s), or even ļ¬re.
If this device is to be used in a small space other than EIA-
standard rack, make sure that there is adequate space around
the device: at least 10 cm above, 1 cm below the bottom
surface, 10 cm at the sides and 10 cm behind.
ā€¢ 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.
ā€¢ Before moving the device, remove all connected cables.
ā€¢ If the device is mounted in an EIA standard rack, carefully
read the section ā€œPrecautions for rack mountingā€. Inadequate
ventilation can result in overheating, possibly causing damage
to the device(s), malfunction, or even ļ¬re.
Connections
ā€¢ Before connecting the device to other devices, turn off the
power for all devices. Also, before turning the power of all
devices on or off, make sure that all volume levels are set to
the minimum. Failing to do so may result in electric shock, or
equipment damage.
ā€¢ Use only speaker cables for connecting speakers to the
speaker jacks. Use of other types of cables may result in ļ¬re.
Maintenance
ā€¢ Remove the power plug from the AC outlet when cleaning the
device.
Handling caution
ā€¢ When the surface of the device heats up, do not touch it until
the panel temperature goes down. Touching the surface with
its high temperature may cause burns.
ā€¢ Avoid inserting or dropping foreign objects (paper, plastic,
metal, etc.) into any gaps or openings on the device (vents,
etc.) If this happens, turn off the power immediately and
unplug the power cord from the AC outlet. Then have the
device inspected by qualiļ¬ed Yamaha service personnel.
ā€¢ Do not rest your weight on the device or place heavy objects
on it. Avoid applying excessive force to the buttons, switches
or connectors.
ā€¢ Avoid pulling the connected cables to prevent injuries or
damage to the device.
Yamaha cannot be held responsible for damage caused by
improper use or modiļ¬cations to the device.
NOTICE
To avoid the possibility of malfunction/ damage to the product,
or damage to other property, follow the notices below.
Handling and maintenance
ā€¢ Do not use the device in the vicinity of a TV, radio, stereo
equipment, mobile phone, or other electric devices.
Otherwise, the device, TV, or radio may generate noise.
ā€¢ 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 disļ¬guration, unstable operation, or
damage to the internal components.
ā€¢ Do not place vinyl, plastic or rubber objects on/under the
device, since this might discolor the panel of the device or
the objects placed on/under the device.
ā€¢ Keep input cables of microphone, etc., devices that contain
sensitive circuits, and the power cord at a distance from
speaker cables and fasten the speaker cables in place.
Since a large amount of current can ļ¬‚ow in a speaker cable,
a magnetic ļ¬eld will be generated and may produce radio
interference and acoustic noise.
ā€¢ When cleaning the device, use a dry and soft cloth. Do not
use paint thinners, solvents, cleaning ļ¬‚uids, or chemical-
impregnated wiping cloths.
ā€¢ Condensation can occur in the device due to rapid, drastic
changes in ambient temperatureā€“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 without turning on the power until the
condensation has completely dried out.
ā€¢ Do not use this device for any purpose other than driving
loudspeakers.
ā€¢ If you put the device on a table or a rack, do not remove the
rubber feet from the device.
ā€¢ Always turn the power off when the device is not in use.
Connectors
XLR-type connectors are wired as follows (IEC60268
standard): pin 1: ground, pin 2: hot (+), and pin 3: cold (-).
Precautions for rack mounting
This unit is rated for operation at ambient temperatures
ranging from 0 to 40 degrees Celsius. If the device is mounted
with other devices in an EIA standard equipment rack, internal
temperatures can exceed the speciļ¬ed upper limit, resulting
in impaired performance or failure. If the device is mounted
in a rack, always observe the following requirements to avoid
heat buildup:
ā€¢ If the device is mounted in a rack with other devices that
generate a signiļ¬cant amount of heat, such as a power
ampliļ¬er, leave more than 1U of space between the device
and other devices (both above and below). Also, make
sure to either leave any open spaces uncovered or install
appropriate ventilating panels to minimize the possibility of
heat buildup.
ā€¢ To ensure sufļ¬cient airļ¬‚ow, leave the rear of the rack open
and position it at least 10 centimeters from walls or other
surfaces. If youā€™ve installed a fan kit, there may be cases
in which closing the rear of the rack will produce a greater
cooling effect. Refer to the rack and fan unit manual for
details.
