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.

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.

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 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 uses 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.

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 applied to the system on an 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

90 6 92 4 95 3 97

100

1 ½

102 1 105 ½ 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.

3 STM AND NUAR NEXO UNIVERSAL RACK

The NEXO Universal Amp Rack (NUAR) provides NEXO users with a scalable, ‘plug & play’, amplified

audio distribution solution of unrivalled power and flexibility. Systems of any size can be configured easily using channel by channel preset selection of any NEXO cabinet, and digital output patching.

The NUAR rack comprises a pair of NEXO NXAMP4X4 amplifiers, twin DMU digital input metering devices, a pair of DPU digital output patching devices and a choice of 110V, 220V or dual-voltage mains distribution boxes providing power to all the components in the rack.

System configuration is simple, using either ESMonitor the new NEXO NeMo iPad® app. NEXO cabinet presets are selected on a channel by channel basis, with selected cabinet names displayed by the DPU for easy output patching.

Digital input metering is provided by the DMU, clearly indicating the presence and status of input signals, including network inputs.

An entirely new library of presets for every single cabinet in the NEXO range delivers linear phase across any system, making it possible to mix and match NEXO cabinets.

Increased efficiency and versatility is inherent in NUAR’s mechanical design. The 14U chassis is suspended within a robust rack case, featuring two sliding doors and an integrated rigging system. This enables up to 3 racks to be flown using an optional bumper and the easy attaching/detaching of a wheel board.

Each NUAR is fully configured and tested at NEXO to provide a truly versatile and tailored ‘Plug & Play’

amplification solution.

3.1 NUAR Components

For a complete description of these units, please refer to NEXO User Manuals.

3.1.1 NXAMP4x4

Among the most powerful amplifiers in the industry, the NXAMP4X4 integrates command, control, amplification and protection functions within a relatively light weight and space-saving 4U rack.

By combining real-time monitoring of temperature, voltage and current with powerful dual-DSP control, the NXAMP4X4 achieves exceptional performance with a high degree of protection for both amplifier and power supply, while simultaneously offering all control parameters required for the speakers.

Page 13

STM AND NUAR NEXO UNIVERSAL RACK Page 13/62

The latest firmware load enables channel by channel preset selection for any speaker in the NEXO range. The result of a 2-year development program, all presets have been revised using FIR filtering to ensure linear phase across any combination of NEXO cabinets, making it possible to mix and match cabinets in a single, coherent system.

EtherSound™ and Dante™ digital networking cards can be installed. Latest generation 24-bit audio converters provide enhanced dynamic range with low latency (500us analogue input to output in ‘flat’ mode), eliminating the need for external A/D conversion.

Improved power efficiency and decreased heat generation comes courtesy of four separate Switch Mode Power Supplies, which ensure high power capacity with low load drive. NEXO amplification technology delivers maximum efficiency in drive performance and power, while providing the audio quality of traditional class AB amplifiers with the heat dissipation of class D amplifiers. This results in a 50% reduction in power consumption, contributing to outstanding sound quality. Converters operate synchronized in the opposite phase, thus cancelling noise.

The NXAMP4X4 delivers 4 x 4000W into 2 Ohm loads, and is available in 110V, 220V and dual voltage versions.

3.1.2 DMU (Digital Metering Unit)

DMU is the ultimate tool for the easy monitoring of any activity on the NXAMP audio inputs. The DMU is totally

driven by the host NXAMP, with signal and power supply coming from the NXAMP’s GPIO port. Front panel

features include 4 analogue XLR inputs plus links, three RJ45 ports for digital audio networking and LED VU meters. Particular care has been taken to ensure minimum insertion losses in the analogue audio signal.

Key Features:

• Intelligent input patch panel offering digital communication with NXAMPs.

• Provides input level meters on all analogue and network inputs.

• Fully passive design on the audio and network paths.

• Powered through the host NXAMP, no need for mains supply.

3.1.3 DPU (Digital Patching Unit)

The DPU is designed to optimise use of the NXAMP’s channel by channel preset selection by automatically routing its outputs to any of 6 output connectors on the DPU front panel. Cabinet names and bridging status are displayed alongside each output, making it easy to wire the system. Security is assured by fully redundant power supplies and dual switching. When connecting DPU to the NXAMP, a routine first checks that the power from the amplifier is coming from the correct channel. If communication is lost with the NXAMP, the DPU retains its configuration until contact is resumed.

Key Features

• Intelligent input patch panel offering digital communication with NXAMPs.

• Provides input level meters on all analogue and network inputs.

• Fully passive design on the audio and network paths.

• Powered through the host NXAMP, no need for mains supply.

NS-1 SIMULATION SOFTWARE Page 21/62

4 NS-1 SIMULATION SOFTWARE

NS-1 software is a R&D simulation tool derived application. It processes measured speaker data with complex mathematical algorithms to assist the user in optimizing system design. Due to the complexity of the interaction of multiple cabinets, it is simply not possible to reliably design curved vertical arrays without using the processing power of a computer to predict the optimum array structure for a given audience geometry. The design logic is far more complex than looking at a section drawing of the venue, measuring the overall angle needed to cover the audience from the cluster location, and dividing by 10 degrees to determine the required amount number of STM modules.

NS-1 is an easy to use tool that allows to shape the energy leaving the cluster to fit the audience. It predicts pressure levels radiated from the system to ensure enough cabinets are provided for the application, as well as mechanical constraints for safe flown systems.

In addition, it provides mechanical information for all clusters in agreement with Structural Analysis Reports (available in the Help section): dimensions, weight, gravity center position, forces, moments, working load and safety factor.

STM Structural Analysis Reports have been conducted by Vom Felde Gmbh, and is currently being submitted to German Certification Organization RWTUV systems GmbH.

NS-1 installation package includes all NEXO User Manuals, Structural Analysis Reports and Certificates PDF files.

NS-1 is a freeware available at www.nexo-sa.com

IMPORTANT

Never install a STM cluster without checking its acoustical performances and mechanical safety in NS-1 prior to installation.

Page 22/62 STM SYSTEM DEPLOYMENT PROCEDURE

5 STM SYSTEM DEPLOYMENT PROCEDURE

Before proceeding with assembly of STM arrays, please ensure that the components are present and undamaged. A component list is appended to this manual. In the event of any shortage, please contact your supplier.

For maximum efficiency the STM rigging system requires three experienced persons for set-up: typically one motor hoist operator, and one STM operator per side of the array. Good synchronisation and crosscheck between the operators are key elements for a reliable and safe set-up.

5.1 SAFETY FIRST

STM Rigging System structural computations and related documents are available in Geosoft2 or at Nexo ([email protected]) upon request.

We include this section to remind you of safe practice when flying the STM system. Please read it carefully. However, user must always apply his or her knowledge, experience and common sense. If in any doubt, seek advice from your supplier or NEXO agent.

This manual offers guidance only for STM loudspeaker systems. References in this manual to other rigging equipment such as motor hoists, steels, shackles etc. are made to clarify the description of STM procedures. The user must ensure that operators are properly trained by other agencies in the use of these items.

The STM Rigging System has been optimised for the deployment of curved vertical or horizontal tangent arrays of STM loudspeakers. Angle adjustment between cabinets has been limited to specific settings to ensure correct acoustic coupling.

The STM Rigging System is a professional precision tool set, and should be handled with extreme care. Only persons who are fully conversant with the operation of the STM Rigging System and provided with suitable safety equipment should deploy GEO Arrays. Misuse of the STM Rigging System could lead to dangerous consequences.

Used and maintained correctly, the STM Rigging System will give many years of reliable service in portable systems. Please take the time to read and understand this manual. Always use GEOSoft2 to determine the optimum angle settings for a particular venue, hang point and curved vertical STM cluster. Applied forces and moments are strongly cabinet quantity and angle configuration dependent. Cluster configuration must be implemented and validated in Geosoft2 prior to installation.

5.1.1 Flown Systems Safety

Always inspect all the rigging components and cabinets for damage before assembly. Pay special attention to the lifting points, and safety clips. If you suspect that any of the components are damaged or defective, DO NOT USE THE AFFECTED PARTS. Contact your supplier for replacements.

Read this manual carefully. Also be familiar with the manuals and safe working procedures for any ancillary equipment that will be used with the STM Rigging System.

Applied forces and moments are strongly cabinet quantity and angle configuration dependent. Cluster configuration must be implemented and validated in Geosoft2 prior to installation.

Ensure that all local and National regulations regarding the safety and operation of flying equipment are understood and adhered to. Information on these regulations can usually be obtained from Local Government Offices.

When deploying a STM system always wear protective headwear, footwear and eye protection. Do not allow inexperienced persons to handle a STM system. Installation personnel should be trained in

loudspeaker flying techniques and should be fully conversant with this manual. Ensure that motor hoists, hoist control systems and ancillary rigging components are currently certified as safe

and that they pass a visual inspection prior to use. Ensure that public and personnel are not allowed to pass beneath the system during the installation process.

The work area should be isolated from public access. Never leave the system unattended during the installation process. Do not place any object, no matter how small or light, on top of the system during the installation procedure.

The object may fall when the system is flown and is likely to cause injury.

Page 23

STM SYSTEM DEPLOYMENT PROCEDURE Page 23/62

Secondary safety steels must be installed once the system has been flown to the operating height. Secondary steels must be fitted irrespective of requirements of the local safety standards applicable to the territory.

Ensure that the system is secure and prevented from pivoting around the motor hoist. Avoid any form of excessive dynamic loading to the assembly (structural computations on STM Rigging System

are based on a 1/1.2 factor for hoist or motor acceleration). NEVER attach any item to the STM system other than the STM accessories. When flying outdoor systems, ensure that the system is not exposed to excessive wind or snow loads and is

protected from rainfall. If wind velocity reaches or exceeds Beaufort 7 (60 km/h – 38 mp/h), the system must be landed. The STM Rigging System requires regular inspection and testing by a competent test centre. NEXO

recommend that the system is load tested and certified annually or more frequently if local regulations require. When de-rigging the system ensure that the same duty of care is given to the procedure as for the installation.

Pack STM components carefully to prevent damage in transit.

5.1.2 Ground Stacking Safety

Statistically, many more injuries occur due to unstable ground stacked PA systems than those associated with flown systems. There are several reasons for this fact, however the message is clear:

Always survey the supporting structure upon which a ground stack is to be built. Always look beneath PA wings to inspect the deck support and if necessary ask for the stage scrims and dressings be removed to allow access.

If the stage surface slopes, as it does in some theatres, ensure that the system is prevented from sliding forwards due to vibration. This may require the fitting of timber battens to the stage floor.

For outdoor systems ensure that that the system is protected from wind forces which might cause the ground stack to become unstable. Wind forces can be huge, especially upon large systems, and should never be

underestimated. Observe meteorological forecasts, calculate the “worst case” effect upon the system prior to

erection and ensure that the system is secured appropriately. Take care when stacking cabinets. Always employ safe lifting procedures and never attempt to build stacks

without sufficient personnel and equipment. Never allow anyone, whether operators, artists or members of the public to climb onto a ground stacked PA

system. Anyone who needs to climb over 2m (6 ft) high should be fitted with suitable safely equipment including a clip-on harness. Please refer to local Health and Safety legislation in your territory. Your dealer can help with advice on access to this information.

Apply the same attention to all safety matters when de-stacking systems. Be aware that safety procedures are as important in the truck and in the warehouse as they are at the venue.

5.1.3 Contacts

Correct training is fundamental to safe practise when working with loudspeakers flying systems. NEXO recommend that users contact local industry associations for information on specialist course.

5.2 General Description

5.2.1 STM Modules

STM SYSTEMS SHARE IN COMMON AN INNOVATIVE PATENTED RIGGING SYSTEM, WHERE ALL ASSEMBLY OPERATIONS ARE DONE FROM

THE BACK OF THE MODULES:

PistonRigTM allows pre-setting of intercabinet angle values on M46 and B112 modules, from 0.2° to 10°

CompassRig™ allows pre-setting of

inter-cabinet angle values between M28 modules, from 0.2° to 15°

REDLock™ handle locks front rigging

points from rear of cabinet

STM rigging hardware allows to fly or stack single column clusters, as well as double and triple column clusters. Each cluster configuration is an assembly of upper and lower rigging parts attached to cabinets in 3 points:

 2 in the front with spring pins fixed inside the bumper,  1 in the back with a quick release pin.

The 2 and 3 columns wide configurations use coupling bars and beams. The entire rigging of the STM is a combination of these different rigging parts. The pages below describe every assembly of STM in flown configuration for single, double or triple column. The array

is always composed of the four modules (M46, B112, S118 and M28) for general description; users will adapt the type and number of cabinets according to their project.

o Lift upper S118 assembly so that next dolly package can roll underneath o Align second dolly package below upper assembly o Lower upper assembly into position, aligning side rigging slots on both sides of the

cabinets

o In order to connect upper assembly to the second set of cabinets, push REDLOCK™

into “LOCK” position; ensure REDLOCK™ safety pins are locked into handle holes

o insert rear quick release pin on the rear hinge so that upper set is connected to lower

set

IMPORTANT

Side locking pins must be flush to rigging plates on both sides of S118

If locking pins appear to be going inwards in relation to rigging plates, S118 must not be flown

Check rear quick release pins are fully engaged and locked

o Repeat the same procedures as before until the full array is off the ground o Install a secondary safety steel between the MLINK or PTILTs and a suitable point in the supporting structure

IMPORTANT

The requirements for secondary safety systems vary with territories. However, the secondary safety steel

MUST have a SWL equivalent to or greater than that of the rigging system
