PRECAUTIONS

PLEASE READ CAREFULLY BEFORE PROCEEDING

* Please keep this manual in a safe place for future reference.

English

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

• 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 included 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.

• Be sure to connect to an appropriate outlet with a protective grounding
connection. Improper grounding can result in electrical shock.

Do not open

• Do not open the device or attempt to disassemble the internal parts or modify
them in any way. The device contains no user-serviceable parts. If it should
appear to be malfunctioning, discontinue use immediately and have it inspected
by qualified Yamaha service personnel.

Water warning

• Do not expose the device to rain, use it near water or in damp or wet conditions,
or place containers on it 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 qualified Yamaha service personnel.

• Never insert or remove an electric plug with wet hands.

If you notice any abnormality

• If the power cord or plug becomes frayed or damaged, or if there is a sudden
loss of sound during use of the device, or if any unusual smells or smoke
should appear to be caused by it, immediately turn off the power switch,
disconnect the electric plug from the outlet, and have the device inspected by
qualified Yamaha service personnel.

• 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 qualified 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

• Remove the electric plug from the outlet when the device is not to be used for
extended periods of time, or during electrical storms.

• 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

• 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 this device is to be mounted in an EIA-standard rack, leave the back of the rack
open and make sure that it is at least 10 cm away from walls or surfaces to
provide better airflow.
In such a situation, these devices can be stacked on top of each other if
necessary. Also, if this device is to be mounted with devices that tend to
generate heat, such as power amplifiers made by another manufacturer, be sure
to keep an adequate gap between this device and the heat-generating devices, or
install ventilation panels or forced ventilation fans to prevent high temperatures
from developing inside this device.
Inadequate ventilation can result in overheating, possibly causing damage to the
device(s), or even fire.

• Do not use the device in a confined, poorly-ventilated location. If this device is
to be used in a small space other than an EIA-standard rack, make sure that
there is adequate space between the device and surrounding walls or other
devices: at least, 10 cm behind and 10 cm above. Inadequate ventilation can
result in overheating, possibly causing damage to the device(s), or even fire.

• Do not expose the device to excessive dust or vibrations, or extreme cold or heat
(such as in direct sunlight, near a heater, or in a car during the day) to prevent
the possibility of panel disfiguration or damage to the internal components.

• 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 front/rear 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.

• Do not use the device in the vicinity of a TV, radio, stereo equipment, mobile
phone, or other electric devices. Doing so may result in noise, both in the device
itself and in the TV or radio next to it.

Connections

• Be sure to turn the POWER switch off before connecting the PW8 to the device
to be powered. Connecting the PW8 to the device to be powered while the
POWER switch is on can damage the device.

Handling caution

• 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.

• Do not insert your fingers or hands in any gaps or openings on the device
(vents, ports, etc.).

•Avoid inserting or dropping foreign objects (paper, plastic, metal, etc.) into any
gaps or openings on the device (vents, ports, 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.

Yamaha cannot be held responsible for damage caused by improper use or modifications to the device, or data that is lost or destroyed.

Always turn the power off when the device is not in use.

Do not turn the POWER switch on and off repeatedly and rapidly. Be sure to wait 10 seconds or more between turning the power to the unit off and then on.

DC PARALLEL INPUT Connector

This connector is used to connect two PW8 units in
parallel. Two PW8s can be connected in this way to
supply power from the two PW8 to the connected
mixer in normal operation. In the event that one unit
shuts down, the other unit will supply 100% of the
power, ensuring an uninterrupted power supply. Use
only the optional PSL1010 Power Supply Link Cable
for this connection. Rotate the connector ring to the
right to connect, or to the left to disconnect.

2

DC OUTPUT Connector

This connector supplies power from the PW8 to the
connected mixer. Always use the cable included in
the mixer to be connected to connect the PW8 to
your mixer.
When using parallel-connected PW8 units, this con­nector connects to the DC PARALLEL INPUT con­nector on the main PW8 unit. Use only the optional
PSL1010 Power Supply Link Cable to connect two
PW8 units in parallel. Rotate the connector ring to the
right to connect, or to the left to disconnect.

3

AC IN Connector

Connects the included power cord here. First, con­nect the power cord to the PW8, then insert the
power cord plug into the AC outlet.

Be sure to use the included power cord. Use
of other cords may result in malfunction, heat
generation, or fire.

Ground Screw Terminal

4

For maximum safety be sure to securely attach a
confirmed ground line to this terminal. The included
power cord has a three-pin plug, so the unit will be
properly grounded if the AC outlet used is grounded.
If the AC outlet is not grounded be sure to properly
connect the GROUND terminal. Proper grounding
not only ensures safety, but it also guarantees mini­mum noise from hum and interference.
