GEOTechnologyisradicallynewthinking

The GEO R&D Project has, to date, resulted in the following patent applications:

The GEO Hyperboloid Reflective Wavesource™ differs radically from the megaphone-variant type horns you know and love (or

hate). “Tried and true” methods will produce entirely unexpected results. HRW technology produces precise and predictable

results.

The Configurable Directivity Flange. A waveguide that allows the operator to alter its behaviour. An unprecedented NEXO

development that is easy to use –once you know how and when.

The Phase Directivity Device needs no operator input to function, but it is reassuring to know that the coupling of the midrange

of the system is considered as important as the high frequencies…

DSP-driven Directional Sub-bass devices are a new approach to controlling LF/VLF acoustic energy.

GEOisnothardtousewhenyouunderstand how…

The technology behind GEO is revolutionary, but it is grounded in years of practical experience with the problems of delivering

high quality professional sound to large audiences at high SPL levels. The GEO toolbox includes NS-1 - a simple yet powerful

and highly predictive design tool. The array assembly system is keyed to the design software and will easily enable you to

deploy your design with great precision. NEXO Digital TDcontroller technology provide driver protection and system optimization

for the GEO S and LS series.

GEOisahighprecisionsystem

The GEO HRW™ controls acoustic energy more precisely than other multiple element waveguides. It also makes GEO less

forgiving of mistakes. Whilst conventional horns never combine into a coherent array, they may deliver acceptable results even

if the design and deployment of the system is less than optimal. This is not the case with GEO where careless installation

produces catastrophic results.

A GEO Tangent Array is not a “line array”

GEO Technology is equally effective in designing and deploying tangent curved vertical or horizontal arrays. For best results in

a specific application the user needs to know how multi-speaker arrays interact with audience geometry, along with the benefits

and drawbacks of curved vertical arrays and horizontal arrays.

Curvedtangentarraysrequiredifferentdesigntechniques

In the past, sound reinforcement professionals have worked with horizontal arrays that use conventional horns to deliver [more

or less] ‘equal power to equal angles’. Curved vertical arrays are now designed to deliver [more or less] equal power to equal

areas’. When arrays use conventional horns, the lack of precision, overlap and interference masks errors in array design and

aiming. The highly precise GEO wavesource responds accurately, consistently and predictably to the design and deployment

of a curved vertical tangent array. This is why the GEO rigging system is designed to control angular splay to 0.1° precision.

GEOcurvedtangentarraysrequiredifferentoperationaltechniques

Over the years, system designers and operators have developed a number of signal processing techniques to disguise and

partly overcome the limitations of horn design. “Frequency shading,” “amplitude shading,” “High Frequency compensation”, all

of these are tools of the advanced sound system operator. NONE OF THESE TECHNIQUES ARE APPLICABLE TO GEO

TANGENT ARRAYS. Instead of enhancing the array’s performance they will severely degrade it.

Take time to learn how to get great results with GEO Technology. It is an investment that will pay off in more satisfied clients,

more efficient operating procedures and more recognition for your skill as a sound system designer and operator. A

comprehensive understanding of GEO theory, tangent arrays, and specific features of the GEO S Series will help you to operate

your system at its full potential.

PLEASE READ CAREFULLY BEFORE PROCEEDING

BASIC PRECAUTIONS

Do not open the speaker system or attempt to disassemble the internal parts or modify them in any way. The speaker system

contains no user-serviceable parts. If it should appear to be malfunctioning or damaged, discontinue use immediately and have

it inspected by qualified NEXO service personnel.

Water exposure: Do not expose the speaker system to direct rain, do not use it near water or in wet conditions. Do not place

containers with liquid on speaker system as they might spill into openings. If any liquid such as water seeps into the speaker

system, have it inspected by qualified NEXO personnel.

Sun exposure: Do not expose the speaker system to direct sun.

Operating temperature with temperate climate: 0°C to +40°C (-20°C to +60°C for storage).

SYSTEM DEPLOYMENT SAFETY RULES

Read User Manual before deployment. Before use of enclosed speaker system, please ensure that anyone

involved in system deployment understands the rigging –stacking –pole mounting safety rules as described

in the speaker system User Manual. Failure to do this exposes people to potential injury or death.

Please check the web site nexo-sa.com for the latest update.

Always consult qualified NEXO personnel if the device installation requires construction work and make sure to observe the

following precautions:

Mounting precautions

- choose mounting hardware and an installation location that can support 4 times the weight of the speaker system;

- do not use speaker system handles for suspended installation;

- do not expose speaker system to excessive dust or vibration, or extreme cold or heat to prevent possibility of component

damage;

- do not place the speaker system in an unstable position from which it might fall accidentally;

- if speaker systems use a stand, ensure that stand specifications are adapted, and that stand height does not exceed

1.40m/55”; never move the stand while the speaker is in position.

- 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 implemented.

- for fixed installations, wind loading has to be taken into account in accordance to the national standards.

Connection and powering precautions

- remove all connected cables before moving the speaker system;

- turn off AC power of all power amplifier units before connecting the speaker system;

- when turning on the AC power to the audio system, always turn on the power amplifier last; when turning the AC power off,

always turn off the power amplifier first;

- when used in cold conditions, a gradual power ramp up should be applied to the system on a 5 mn period to allow the

loudspeaker components to stabilize during the very first minutes of usage.

Inspect the speaker system periodically.

HIGH SOUND PRESSURE LEVELS

Exposure to extremely high noise levels may cause permanent hearing loss. Individuals vary considerably

in susceptibility to noise-induced hearing loss but nearly everyone will lose some hearing if exposed to

sufficiently intense noise for a sufficient period of time. The U.S. Government’s Occupational and Health

Administration (OSHA) has specified the following permissible noise level exposures: Sound Duration Per

Day In Hours

Sound Level dBA, Slow Response

100

1 ½

102

105

110

¼ or less

115

According to OSHA, any exposure in excess of the above permissible limits could result in some hearing loss. Ear plugs or

protectors to the ear canals or over the ears must be worn when operating this amplification system in order to prevent

permanent hearing loss, if exposure is in excess of the limits as set forth above. To ensure against potentially dangerous

exposure to high sound pressure levels, it is recommended that all persons exposed to equipment capable of producing high

sound pressure levels such as this amplification system be protected by hearing protectors while this unit is in operation.

DISPOSAL OF OLD ELECTRICAL & ELECTRONIC EQUIPMENT

This symbol on the product or on its packaging indicates that it shall not be treated as household waste.

Instead it shall be handed over to the applicable collection point for the recycling of electrical and electronic

equipment. By ensuring this product is disposed of correctly, you will help prevent potential negative

consequence for the environment and human health, which could otherwise be caused by inappropriate

waste handling of this product.The recycling of materials will help to conserve natural resources. For more

detailed information about recycling of this product, please contact your local city office, your household

waste disposal service or the shop where you purchased the product.
