NEXO eLS18 18 Inch Passive Install Subwoofer

Product Information

Specifications

• Product Type: eLS18
• Serial Number: DP6766-01a-DI
• IP Rating: IP55

Description

The eLS18 is a compact and powerful subwoofer designed to complement the ePS10 and ePS12. It is equipped with 2 pairs of screw terminal blocks for easy wiring. The permissible cable size ranges from 0.75 mm2 to 3.31 mm2 (12 to 15 AWG) with a maximum outside diameter of 11mm.

To wire the eLS18, slit the membrane of the grommet crosswise, pass the cable through, and make the connection to the screw terminals. Place the IPCOV correctly to ensure IP55 protection.

Warnings and Precautions

Warnings:

• Select screws and mounting location supporting 4 times the system weight.
• Do not expose the system to excessive dust, vibrations, extreme cold or hot temperatures to avoid damaging components.
• Do not place the system in an unstable position to prevent accidental falls.
• If the system is used on a tripod, 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.

Safety Informations:

• Unplug connected cables before moving the system.
• Power off the system before connecting or disconnecting any cables.
• When switching on the installation, power on the amplifier last. When switching off the installation, shut off the amplifier first.
• If you work in cold temperatures, gradually raise the level to the nominal value during the first few minutes of use to allow system components to stabilize.
• Regularly check the system condition.

High Sound Pressure Levels

Exposure to very high sound pressure levels may cause permanent hearing loss. The OSHA (Occupational Safety and Health Administration) American Agency specifies the following maximal exposures:

115

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 INFORMATION

• 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.
