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 user­repairable 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 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 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:

DESCRIPTION

Page 4 / 20 GEOM1210-I - GEOM1220-I

DESCRIPTION

 GEOM1210-I and GEOM1220-I are a mid-size line array, 2 ways active/passive, with a 12’’ LF and a 1.4’’ HF.
 You can change the HF horizontal directivity from 80° to 120° by adding a pair of magnetic flanges.
 The GEOM12 can be stacked of flown with the HF waveguide exit on the left or the right side of the front panel, allowing

to broaden or narrow the stereo image depending on your need and the characteristics of the venue. We recommend to
build system with the HF waveguide on the outside of each assembly (larger stereo image).

 GEOM1210-I: 10° vertical dispersion
 GEOM1220-I: 20° vertical dispersion
 Versions:

• GEOM1210-I: fix installations; Black

• GEOM1210-IPW: fix installations; White

• GEOM1220-I: fix installations; Black

• GEOM1220--PW: fix installations; White

 Connectors:

• GEOM1210-I/1220-I: two cable-glands (clamping range, Ø 10 to 17mm), four fast connectors behind the plate.

- Remove the connecting plate.

- Pass the cables through the cable-gland.

- Connect to the fast connectors:

• ACTIVE

o LF (+) Red / (-) Black.
o HF (+) Orange / (-) Grey

• PASSIVE: (+) Orange / (-) Grey

- Tight the cable-gland and remount the connecting plate.

 Amplification:

• The GEOM12 cabinets 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 GEOM12 usable with each solution.
