PRECAUTIONS
PLEASE READ CAREFULLY BEFORE
PROCEEDING
Please keep this manual in a safe place for
future reference.
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:
Power supply/power cord
• 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.
• Only use the voltage specified as correct for the device.
The required voltage is printed on the name plate of the
device.
• Use only the supplied power cord/plug.
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.
• Check the electric plug and each jack periodically, and
remove any dirt or dust which may have accumulated. Failure
to do so may cause electrical shock, short-circuiting or fire.
• 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.
• Remove the electric plug from the outlet when the device is
not to be used for extended periods of time, or during
electrical storms.
• Be sure to connect to an appropriate outlet with a
protective grounding connection.
Do not open

- Do not use the device in a confined, poorly-ventilated
location.
Inadequate ventilation can result in overheating, possibly
causing damage to the device(s), or even fire. If this device
is to be used in a small space other than an EIA-standard
rack, make sure that there is adequate space around the
device: at least 30cm above, 30cm at the sides and 30cm
behind.
• 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.
• If the device is mounted in an EIA standard rack, carefully
read the section “Precautions for Rack Mounting” on page
2. Inadequate ventilation can result in overheating, possibly
causing damage to the device(s), malfunction, or even fire.
Connections
• Do not use speaker cables with a metal-housing connector.
Doing so may result in electrical shock due to differences
in voltage. Use speaker cables with a nonmetal-housing
connector, or with a insulated-housing connector.
• 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.
• Use only speaker cables for connecting speakers to the
speaker jacks. Use of other types of cables may result in
fire.
Maintenance
• Remove the power plug from the AC outlet when cleaning
the device.
Handling caution
• Avoid inserting or dropping foreign objects (paper, plastic,
metal, etc.) into any gaps or openings on the device (vents,
panel, etc.) If this happens, immediately turn off the power,
unplug the power cord from the AC outlet, and have the
device inspected by qualified Yamaha service personnel.
• Do not rest your weight on the device or place heavy
objects on it. Avoid applying excessive force to the buttons,

Precautions for Rack Mounting
This mixer is rated for operation at ambient temperatures ranging from 0 to 40 degrees
Celsius. If you install this mixer along with other devices in a poorly ventilated EIA
standards rack, the ambient temperature inside the rack may rise, resulting in
inefficient performance. Be sure to rack-mount in the following conditions so the mixer
does not overheat.
• When mounting the mixer in a rack with devices such as power amplifiers that generate a
significant amount of heat, leave more than 1U of space between it and other equipment. Also,
either leave the open spaces uncovered or install appropriate ventilating panels to minimize the
possibility of heat buildup.
• To ensure sufficient airflow, leave the rear of the rack open. If you’ve installed a fan kit in the rack,
there may be cases in which closing the rear of the rack will produce a greater cooling effect.
Refer to the rack and/or fan kit manual for details.
