WARNINGS
PRECAUTIONS
-
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 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.
- cations are adapted and that its height does not exceed
.
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 GEOM6B-GEOM620
DESCRIPTION
→GEOM620 and GEOM6B are a mid-size line array. GEOM620 is a 2 ways passive, with a 6.5
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).
→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-
→Amplification:
•The GEOM6 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 GEOM6 speakers and MSUB12 subwoofers usable with each solution.

PRESET GEOM6
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.
1Box
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;
PRESET GEOM6
Page 6 / 20 GEOM6B-GEOM620
2-3Boxes
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.
PRESET GEOM6
GEOM6B-GEOM620 Page 7 / 20
4-6Boxes
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.
PRESET GEOM6
Page 8 / 20 GEOM6B-GEOM620
7-12Boxes
For very long throw application, MSUB12 should be deployed using the 50-120 Hz setup (120 Hz
crossover should be used for GEOM6).
