WARNINGS
PRECAUTIONS
Do not open the speaker, do not try to disassemble it neither to modify it in any way. The system doesn’t include any user-
repairable part.
If the system seems to be malfunctioning or damaged, stop using it at once and have it repaired by a NEXO qualified technician.
Do not expose the system directly to the sun or to the rain, do not immerse it into fluids, do not place objects filled with liquid on the
system. If a liquid gets into the system, please have it inspected by a NEXO qualified technician.
The connection should be performed by qualified technician, by ensuring that power is off.
Operating temperature with temperate climate: 0°C to +40°C (+32°F to +104); -20°C à +60°C (-4°F to +140°F) for storage.
SAFETY INFORMATIONS
Read this manual before using the speaker.
Keep this manual available for further reference.
Observe all warnings and cautions.
Please check the NEXO Web site nexo-sa.com to get the most up-to-date version of this manual.
Ensure you are aware of the safety rules applying to rigging, stacking or installing on tripod or speaker stand. Failure to observe
these rules may expose persons to potential wounds or even death.
Only use the system with accessories specified by NEXO.
Please always consult a NEXO-accredited technician if the installation needs architectural works and observe following precautions:
Mounting Precautions:
-Do not expose the system to excessive dust, vibrations, to extreme cold or hot temperatures, to reduce the risk of damaging
components.
-Do not place the system in an unstable position: it could fall accidentally.
Connection and Powering Precautions:
-Unplug connected cables before moving the system.
-Power off the system before connecting the system.
-When switching on the installation, the amplifier must be powered last; when switching the installation off, shut off the amplifier
first.
-If you work by cold temperatures, progressively raise the level to nominal value during the first minutes of use, to allow the
system components to stabilize.
Please check regularly the system condition.
HIGH SOUND PRESSURE LEVELS
Exposure to very high sound pressure levels may cause permanent hearing losses. Degrees of hearing losses may be different
from one person to another, but almost everybody will be affected if exposed to high sound pressure levels during a long period of
time. The OSHA (Occupational Safety and Health Administration) American Agency specified the following maximal exposures:

To unlock cabinets, simply lift one of the side handles: cabinets
will unlock with almost no effort.

DESCRIPTION
45N12 Page 5/ 14
DESCRIPTION
→The 45N12 is a monitor which brings all the benefits of line-array technology to the stage;
→HF dispersion:
•Horizontal 30° - Scalable 30° steps when arrayed
•Diagonal (Coupling Plane) 22.5° - Scalable 22.5° steps when arrayed
•Vertical 60° (Asymmetrical -45° / + 15°)
→The speaker is equipped with two NL4 connectors, the 4 pins of the 2 sockets are connected in parallel within the enclosure.
•PASSIVE MODE : 2+/2-
•ACTIVE MODE : LF (1+/1-) –HF (2+/2-)
→Amplification
•The 45N12 cabinet MUST be used with a NEXO processor to handle EQ, phase alignment, crossover and
excursion/thermal protection for the system loudspeakers.
•The following table shows the number of 45N12 usable with each solution.

→Configuring 45N12 for Passive or Active Mode
IMPORTANT 45N12 are factory configured in active mode
In order to change active or passive configuration:
•Remove the TORX screws that hold the rear/bottom metal panel;
•Remove the rear/bottom metal panel to access passive network WAGO connectors.
•In Passive Mode, CNX WAGO connector should be inserted in “Passive In”, and loudspeakers WAGO connectors
should be inserted in connector “Passive Out”.
•In Active Mode, CNX WAGO Connector should be directly connected to loudspeakers WAGO connectors (passive
filter is then bypassed).
