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

• 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

• Do not place the device in an unstable position where it might

accidentally fall over.

• 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 ﬁre.

• When installing the device and you wish to dissipate heat on it:

– Do not cover it with any cloth.

– Do not install it on a carpet or rug.

– Make sure the top surface faces up; do not install on its

sides or upside down.

– 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 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.

• 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”. Inadequate

ventilation can result in overheating, possibly causing damage

to the device(s), malfunction, or even ﬁre.

Connections

• 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

• 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.

• 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 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, switches

or connectors.

• 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 modiﬁcations 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

• 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.

• 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/under the

device, since this might discolor the panel of the device or

the objects placed on/under the device.

• 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 ﬂow in a speaker cable,

a magnetic ﬁeld will be generated and may produce radio

interference and acoustic noise.

• 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 without turning on the power until the

condensation has completely dried out.

• Do not use this device for any purpose other than driving

loudspeakers.

• If you put the device on a table or a rack, do not remove the

rubber feet from the device.

• 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 speciﬁed 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:

• If the device is mounted in a rack with other devices that

generate a signiﬁcant amount of heat, such as a power

ampliﬁer, 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.

• To ensure sufﬁcient airﬂow, leave the rear of the rack open

and position it at least 10 centimeters from walls or other

surfaces. If you’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.
