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 NEXO-
SA 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 NEXO-SA 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 NEXO-SA 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 NEXO-SA 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.
• If you are using the NXAMP4X4, be sure to plug each power cord into separate
branch circuits employing separate service grounds. Plugging into the same circuit
can result in electrical shock.
• To disconnect the NXAMP4X4 from the mains, unplug both power cords.
Location
• When transporting or moving the device, always use two or more people.
Attempting to lift the device by yourself may damage your back, result in other
injury, or cause damage to the device itself.
• 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. Also, if this
device is to be mounted with devices that tend to generate heat, such as power
amplifiers, be sure to keep an adequate gap between this device and the heat-
generating devices or install ventilation panels 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 at the sides,
15 cm behind and 40 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 th e 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
• 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
• Inspect the cooling fans and clean them periodically. Dust and dirt can seriously
degrade the effectiveness of the cooling fan and result in malfunction or fire.
• Remove the power plug from the AC outlet when cleaning the device.
Handling caution
• 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.
• Do not insert your fingers or hands in any gaps or openings on the device (vents…)
• Avoid inserting or dropping foreign objects (paper, plastic, metal, etc.) into any
gaps or openings on the device (vents, etc.) If this h
appens, turn off the power
immediately and unplug the power cord from the AC outlet. Then have the device
inspected by qualified NEXO-SA service personnel.
• 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 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 this device for any purpose other than driving loudspeakers.
