WARNINGSWARNINGS
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 aliquid 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 beimplanted.
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 systemcomponents 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 toanother, but almost everybody will be affected if exposed to high sound pressure levels during a long period of time. The OSHA (OccupationalSafety and Health Administration) American Agency specified the following maximal exposures:

DESCRIPTIONDESCRIPTION→ The L18 is a compact and powerful subwoofer, ideally complementing PLUS serie speakers→ The L18 subwoofer is equipped with two Speakon NL4 connectors, with parallel-wired pins,→L18 uses the 1+/1- pins, (2+/2- through).

→ Amplification•

The L18 subwoofer must be used with a NEXO processor to handle EQ, phase alignment, crossover andexcursion/thermal protection for the system loudspeaker.

PRESETPRESET
Please consult nexo-sa.com for NEXO TD Controllers firmware information.
There are two setting range for surrounding speaker L18:
→ “OMNI” Setups; For a traditional use of the subwoofer in omnidirectional radiation (require at least one subwoofer and achannel of amplifier).
•

Omnidirectional Main setup, with low-pass at 60, 85 or 120 Hz.

•Omnidirectional Monitor setup, with low-pass at 60, 85 or 120 Hz.

→ “CARDIO” Setups; For a directional use (cardioid) of subwoofers (require at least two subwoofers and two channels ofamplifier).
•Cardioid back and front setups, with low-pass at 60, 85 or 120 Hz.
-•

Setup « FR » (Front) for the subwoofer pointed at the audience.
Setup « BA » (Back) for the subwoofer turned around.

The ideal ratio for a directional use is 2x L18 in CARDIO FRONT mode on top of 1x Reversed L18 in CARDIO BACK
mode. From 1:1 to 3:1 ratio can be used.
