SAFETY PRECAUTIONS
NXAMPMK2 USER MANUAL PAGE 7 / 70
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 the 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 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 place the device in a location where it may come into contact with corrosive gases or salt air. Doing
so may result in malfunction.
Do not expose the device to excessive dust or vibrations, or extreme cold or heat (such as 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 instable position where it might accidentally fall over.
Do not block the vents. This device has ventilation holes at front and back to prevent the internal temperature
from becoming too high. In particular, do not place the device on the front or the back. 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.
Keep the device out of reach of children, to keep them from putting their fingers into openings on the
equipment and accidentally being injured.
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.
XLR-type connectors are wired as follows (IEC60268 standard): pin 1: ground, pin 2: hot (+) and pin 3: cold
(-).
Use only speakON NL4 plugs for connecting SP connectors.
MAINTENANCE
Inspect the ventilation holes and clean them periodically. Dust and dirt can seriously degrade the
effectiveness of the cooling and result in malfunction or fire.
Remove the power plug from the AC outlet when cleaning the device.
The performance of components with moving contacts, such as switches, volume controls, and connectors,
deteriorates over time. Consult qualified NEXO service personnel about replacing deflective components.
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 happens, turn off the power immediately and unplug the power cord from the AC
outlet. Then have the device inspected by qualified NEXO 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.
