2WARNINGS
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:
- Please select screws and mounting location supporting 4 times the system weight.
- Do not expose thesystem to excessive dust, vibrations, to extremecold or hot temperatures, to reduce the risk of damaging
components.
- Do not place the system in an unstable position: it could fall accidentally.
- For fixed installations wind loading has to be taken into account in accordance to the national standards.
- If the system is used on a tripod, please ensure the tripod’s specifications are adapted and that it’s 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:

Page 8/16 DESCRIPTION
5DESCRIPTION
- GEOM1012-I and GEOM1025-I are a compact high-technology line array, 2 ways passive, with a 10’’ LF and a 1.4’’
HF.
You can change the HF horizontal directivity by adding a pair of magnetic flanges.
- GEOM1012-I : 12° vertical dispersion
- GEOM1025-I : 25° vertical dispersion
- Versions :
oGEOM1012-I: fix installations; Black
oGEOM1012-I-PW: fix installations; White
oGEOM1025-I: fix installations; Black
oGEOM1025-I-PW: fix installations; White
oFor Touring applications, see manual GEOM1012 / GEOM1025
- Connectors:
oGEOM1012-I/1025-I: two cable-glands, two fast connectors behind the plate.
▪Remove the connecting plate.
▪Pass the cables through the cable-gland.
•Maximum cable outside diameter 12mm
•Maximum gauge wire:
oSolid cable: 2.5 mm2/ AWG13
oMulti-stand cord: 4 mm2/ AWG11
▪Prepare cable as below:
▪
▪Connect to the fast connectors (+): Brown (or Red) / (-): Blue (or Black).
▪Remount the connecting plate.
▪Tight the cable-gland and adjust the length.
▪Seal the cabinet with the provided blind plug on the unused cable gland.
- Amplification:
oThe GEOM10 cabinets MUST be used with a NEXO processor to handle EQ, phase alignment, crossover
and excursion/thermal protection for the system loudspeakers. There are two NEXO processor series
supporting the GEOM10 cabinet: NXAMP (4-channel) amplified processors and DTD processors (stereo +
sub).
