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.

• Remove the electric plug from the outlet when the device is not to

be used for extended periods of time, or during electrical storms.

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/

bottom/sides 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 attempting to dissipate heat on the device, when

installing 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.

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.

• 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, electricity is still ﬂowing to the product at the minimum

level. When you are not using the product for a long time,

make sure to unplug the power cord from the wall AC outlet.

• 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. Before turning the power on or off for all

devices, set all volume levels to minimum.

• 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, and avoid use excessive force on the buttons, switches

or connectors.

• Do not use the device 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.

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, 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.

• Avoid setting all equalizer controls and faders to their

maximum. Depending on the condition of the connected

devices, doing so may cause feedback and may damage the

speakers.

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

loudspeakers.

• When turning on the AC power in your audio system, always

turn on the device LAST, to avoid speaker damage. When

turning the power off, the device should be turned off FIRST for

the same reason.

• 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.
