Warnings and Precautions

Select screws and mounting locations that can support 4 times the system weight.
Avoid exposing the system to excessive dust, vibrations, extreme cold or hot temperatures to prevent damage to components.
Ensure the system is placed in a stable position to prevent accidental falls.
If using the system on a tripod, ensure the tripod’s specifications are suitable and its height does not exceed 1.40m/55. Do not move the tripod with the system in position.
Before moving the system, unplug connected cables and power it off.
When switching on or off the installation, power off/on the amplifier last/first.
If working in cold temperatures, gradually raise the level to nominal value during the first minutes of use to allow system components to stabilize.
Regularly check the system condition.
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 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 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:

Number of Hours	Sound Pressure Level (dBA), Slow Response
8	90
6	92
4	95
3	97
2	100
1 ½	102
1	105
½	110
¼ or less	115

Description **

**

The GEOM6 is a loudspeaker that can be stacked or flown with the HF waveguide exit on the left or right side of the front panel. This allows you to broaden or narrow the stereo image depending on your needs and the characteristics of the venue. It is recommended to build a system with the HF waveguide on the outside of each assembly for a larger stereo image.

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 a bass 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 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).

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.

Default Cross over on one box 50 Hz Front Fill, multi-diff, sound reinforcement all short throw application; High SPL Small system using 2x GEOM6 and 2x MSUB12 in 85 Hz;

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

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

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.

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.
