Maîtriser les contraintes techniques pour sécuriser vos installations
Une structure de 200m² supporte jusqu'à 100 tonnes selon l'EN 13814. Mais connaissez-vous les coefficients de sécurité obligatoires ? Les contraintes de vent selon l'Eurocode 1 ? L'impact sur vos autorisations préfectorales ?

Défis des Structures
Scéniques Événementielles
Monter une structure événementielle nécessite bien plus qu'un simple assemblage. Entre normes européennes, réglementations locales et contraintes techniques, chaque projet présente des défis spécifiques souvent découverts trop tard.
Calculs de Charge Complexes
L'addition n'est pas si simple
Votre écran LED de 40m² pèse 800kg. Simple ? Non. S'ajoutent : charge dynamique du vent, coefficients de sécurité γ=1,5, répartition non uniforme, flèche admissible L/300...
L'Expertise Fait la Différence
Nous appliquons les Eurocodes et normes CTS pour dimensionner précisément vos structures. Sécurité garantie, budget maîtrisé.
Contraintes de Site Spécifiques
Chaque lieu a ses pièges cachés
Sol en marbre historique ? Interdit de percer. Parking souterrain ? Charge limitée à 250kg/m². Monument classé ? Distances réglementaires à respecter.
Anticipation = Sérénité
Notre expertise terrain nous permet d'identifier les contraintes en amont. Pas de mauvaises surprises, solutions adaptées garanties.
Météo et Forces du Vent
L'invisible qui fait tomber les structures
L'Eurocode 1 définit des zones de vent : 0,8 kN/m² en ville, 1,3 kN/m² en bord de mer. Une structure de 10m de haut subit plusieurs tonnes de poussée latérale.
Sécurité Sans Compromis
Nous intégrons les contraintes météo dès la conception. Ancrages dimensionnés, protocoles d'urgence établis.
Coordination Multi-acteurs
Quand tout le monde doit valider
Un projet structure implique : bureau de contrôle, commission de sécurité, mairie, préfecture, architecte du site, assurances, autres prestataires techniques...
Coordination = Notre Métier
Nous pilotons l'ensemble des validations pour vous. Un seul interlocuteur, toutes les autorisations obtenues.

Choosing your Providers
Sound System
Not all audio providers are proficient in the same technologies. Here are the essential skills to verify and the right questions to ask to avoid unpleasant surprises.
Essential Technical Skills
Verify that your provider is proficient in these technical areas based on your event type.
Advanced RF Proficiency
Complex RF transmission requires specialized expertise for multi-channel coordination and interference management in dense environments.
Audio IP Protocols
DANTE, NDI, ST 2110 are the new standards for professional audio distribution. Verify your provider's proficiency in these technologies.
Hybrid Events
High-quality audio streaming with remote participants requires specific expertise to avoid latency and ensure real-time interaction.
Support & Monitoring
Real-time monitoring and rapid response capability are essential to ensure consistent audio quality during the event.

Our Approach
Sound Reinforcement Technology
Our expertise in broadcast and RF transmission has taught us that modern event sound reinforcement requires a methodical approach to anticipate and resolve technical challenges.
Ten years of experience in sound reinforcement coordination have allowed us to observe that successful events share a common approach: technical anticipation takes precedence over improvisation.
Our broadcast TV and RF transmission background gives us a different perspective on event sound reinforcement. We apply the rigorous standards of broadcast to corporate events.
This experience allows us to select the right service providers and coordinate technical teams that master current standards: DANTE, RF transmission, low-latency streaming.
Areas of Expertise
Coordination Process
Proven methodology for coordinating the technical aspects of your sound system
Technical Audit
Preliminary RF analysis of the site, bandwidth assessment, identification of specific acoustic constraints.
Vendor Selection
Coordination of specialized service providers according to needs: DANTE expertise, RF transmission, hybrid streaming.
Testing & Validation
Complete technical rehearsal, latency tests, frequency plan validation, team coordination.
On-site Management
Real-time monitoring of audio quality, technical coordination, preventive intervention if needed.
What Sets Us Apart
Our technical approach stems from broadcast and RF transmission experience
Technical Expertise
Broadcast TV background gives us a rigorous approach to sound reinforcement. We speak ST 2110, NDI, DANTE and understand the real synchronization challenges.
Specialized Network
Partnerships with service providers mastering recent technologies. Our network includes DANTE certified technicians and RF transmission specialists.
Preventive Approach
Proactive methodology derived from broadcasting: systematic RF analysis, preliminary tests, contingency plans. We avoid problems rather than endure them.
Human Coordination
Placement of the right skills in the right positions. We know how to identify the technical profiles needed based on the complexity of your event.

Event Sound System FAQ
Frequently asked questions about the technical aspects of modern event sound systems
A preliminary RF analysis of the site remains the crucial step. It identifies available frequencies and potential sources of interference (Wi-Fi, 4G, other equipment).
- Professional RF scan with spectrum analyzer to map the environment
- Calculated frequency coordination with sufficient guard intervals
- Compatible equipment (Shure Axient, Sennheiser 6000) with automatic management
- Preliminary tests under real conditions with all active microphones
With a rigorous methodology, 15 to 32 RF microphones can operate simultaneously without interference.
For real-time interaction, audio latency must remain below 50ms. Beyond that, exchanges become difficult between on-site and remote participants.
- < 50ms: Natural, imperceptible interaction possible
- 50-150ms: Noticeable but tolerable delay for conferences
- > 300ms: Major problem, impossible interaction
Technical solutions: NDI, ST 2110 with PTP, or DANTE to stay below the critical threshold. Conventional platforms (Zoom, Teams) often exceed 200ms.
The choice depends on the complexity of your event and the audio distribution distances.
Prioritize DANTE if:
- Complex distribution: multiple rooms, remote listening areas
- Hybrid event with simultaneous streaming and recording
- Flexibility required: audio routing that can be modified in real time
Stay analog if: simple event, single zone, technical teams not trained in DANTE. The technical complexity must match the actual need.
Basic tests are not enough. You have to simulate the real conditions of your event.
Testing methodology:
- Real-world condition test: same time, same network load as the event
- Load simulation: exact number of participants connected simultaneously
- Stability tests: maintain the flow for the entire duration of the event
- Latency measurement: verify audio-video synchronization in real time
Practical calculation: 2 Mbps per participant for high-quality audio streaming. Allow 30% extra for unstable network compensation.
Technical honesty is better than improvisation. A service provider who acknowledges their limitations inspires more confidence.
Possible options:
- Express training: some service providers can be trained quickly
- Technical partnership: collaborate with a specialist for your event
- Technical simplification: adapt the solution to the available skills
- Change service provider: sometimes necessary for complex events
Our role: to identify these situations upstream and offer solutions adapted to your budget and schedule.
