115

Equipment Locations and Assembly

The P18-I speaker has 3 locations for hanging, 1 on the back and on both sides. The depth of the M10 thread is 14mm (0.55 inch).

To assemble on a distance rod or speaker stand

1. Place the distance rod on the connector plate (M20) of the Sub.
2. Put PLADAPT on P18-I.
3. Put the assembly on the distance rod/monitor stand with a diameter of 35mm. It may require two people to handle P18.

Important guidelines for speaker stand assembly

• The speaker stand must be rated for P18 weight.
• The speaker stand must always be installed on a horizontal surface.
• The stand height and footprint must be defined to prevent assembly collapse.
• Ensure that the audience is not allowed within a safety area with a radius equal to or higher than the assembly height.
• Test the steadiness of the assembly by pushing it in all directions.

FAQ

• Q: How should I select screws and mounting location for the system?
  A: Please select screws and mounting location supporting 4 times  the system weight.

• Q: Can I expose the system to extreme temperatures?
  A: No, to reduce the risk of damaging components, do not expose the system to extreme cold or hot temperatures.

• Q: Can I place the system on an unstable position?
  A: No, do not place the system in an unstable position as it could fall accidentally.

• Q: How should I power on/off the system?
  A: When switching on the installation, power on the amplifier last. When switching the installation off, shut off the amplifier first.
  Q: What should I do if I work in cold temperatures?
  A: If you work in cold temperatures, progressively raise the level to nominal value during the first minutes of use to allow the system components to stabilize.

• Q: How can I prevent hearing losses from high sound pressure levels?
  A: Exposure to very high sound pressure levels may cause permanent hearing losses. It is recommended to follow the specified maximal exposures and take breaks from exposure.

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.
• When flying outdoor systems ensure that the system is not exposed to excessive wind or snow loads and is protected from rainfall.
• In case of wind greater than 8 on Beaufort scale (72km/h – 45mph), a touring system has to be landed or an additional securing has to be implanted.
• For fixed installations, wind loading has to be taken into account in accordance to the national standards
• 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

• Please select screws and mounting location supporting 4 times the system weight.
• 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.
• If the system is used on a tripod, please ensure the tripod’s specifications are adapted and that its height does not exceed 1.40m/55”. Do not move the tripod with the system in position.

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

Amplification

• The P18 speakers must be used with a NEXO processor to handle EQ, phase alignment, crossover and excursion/thermal protection for the system loudspeaker. There are two NEXO processor series supporting the P18 speakers: NXAMP (4 channels) amplified processors and DTD processors (stereo + sub). DTD processors ensure optimal performances when used with DTDAMP power amplifiers.
