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→ GEOM620 and GEOM6B are a mid-size line array. GEOM620 is a 2 ways passive, with a 6.5’’ LF and a 1’’ HF; GEOM6B is abass extension with a 6.5” driver.
With GEOM620, you can change the HF horizontal directivity from 80° to 120° by adding a pair of flanges.
→ The GEOM6 can be stacked of flown with the HF waveguide exit on the left or the right side of the front panel, allowing tobroaden 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).
→ Versions:•GEOM620: Touring or fix application; Black•GEOM620-PW: Touring or fix application; White•

GEOM6B: Touring or fix application; Black•GEOM6-PW: Touring or fix application; White→ Connectors:•GEOM620/6B: two NL4 connectors, the 4 pins of the 2 sockets are connected in parallel within the enclosure.
-GEOM620: 2+/2-.
GEOM6B: 1+/1-1 //→ Amplification:•The GEOM6 cabinets MUST be used with a NEXO processor to handle EQ, phase alignment, crossover andexcursion/thermal protection for the system loudspeakers.

Please consult nexo-sa.com for NEXO TD Controllers firmware information.
For the GEOM620 or GEOM6B, with or without directivity flanges, the following setups are available:
Passive Mode•

Setup for one stand-alone box, with high-pass at 50, 60, 75, 85, 95 or 120 Hz.

•

Setup for arrays from 2 to 3 boxes, with high-pass at 50, 60, 75, 85, 95 or 120 Hz.

•

Setup for arrays from 4 to 6 boxes, with high-pass at 50, 60, 75, 85, 95 or 120 Hz.

•

Setup for arrays from 7 to 12 boxes, with high-pass at 50, 60, 75, 85, 95 or 120Hz.

•Setup for Stack Monitor, with high-pass at 50, 60 or 75 Hz.

2-3 Boxes

For small flying or stacking configuration, mid throw application used at 60 Hz without MSUB12 and 85 Hzwith set up 50-85 Hz for MSUB12.

For stack configuration using MSUB12 in OMNI or CARDIO mode with 1 Back and 2 Front and GEOM6on top of them, MSUB12 should use the 50-85 Hz setup (85 Hz crossover should be used for GEOM6 aswell). A small overlap could have impact if needed, for example use MSUB12 with 50-120 Hz setup.

GEOM6B-GEOM620

PRESET GEOM64-6 Boxes

For long throw flying application used in GEOM6 at 60 Hz without Sub. MSUB12 should use the 50-120
Hz setup (120 Hz crossover should be used for GEOM6 as well). If a larger stacked Sub is used all
together, MSUB12 should use the 63-120 Hz setup.

7-12 Boxes
HFTT

For very long throw application, MSUB12 should be deployed using the 50-120 Hz setup (120 Hz
crossover should be used for GEOM6).
Don’t forget to put HF Waveguide either to the exterior or the interior of the venue.
