SOLUTIONS FOR STADIUMS AND SPORT/EVENT VENUES

The main purpose of the voice alarm system (VA) is to effectively warn the public of eminent danger thus allowing efficient evacuation. The warning and informative functions can be triggered automatically via the fire alarm system or manually using fireman microphones. The audible alarm system is designed to cover all areas of a building to reach its occupants in the event of an emergency.

More importantly, MULTIVES system can be successfully used to fulfil non-emergency functions i.e. it can provide standard public address system functionality. Thanks to its excellent audio setup, in normal conditions it can be used to address public for specific announcements (using either zone microphones or external sound sources) and/or to provide background music in venues such as shopping centres, sports halls etc.

MULTIVES offers advanced sound processing functions and audio signal matrix switching characteristic of professional acoustic systems:
• flexible configuration into separate zones and ease of management
• simultaneous processing of multiple sound sources
• effective use of a full acoustic bandwidth
• high quality transducers and digital processors ensure excellent sound quality and signal dynamics
• fully digitalised transmission
• in-built DSP processors used for sound processing and management of the system
• signal correction at audio inputs and outputs
• ability to define delays on loudspeaker lines
• in-built limiters at each audio output
• elimination of acoustic feedback
• fully configurable messaging system allowing to issue separate announcements to individual sectors within the venue.

MULTIVES is a fully certified system combining the functionality of a voice alarm system and a professional sound system. As such, it provides flexible management of loudspeaker zones covering the sectors, stands and other parts of the venue. Use of MULTIVES successfully addresses technical and legal issues ensuing from installing VA and PS systems in sports halls and event venues.

Communication protocols RS485, TCP/IP and in-built audio inputs/outputs ensure seamless connectivity with external devices such as mixer consoles, wireless microphone sets, translation systems or induction loops for the hearing-impaired.

  • Compliance with EN 54-16, EN54-4

  • up to 44 loudspeaker lines per Control Unit

  • Ability to simultaneously broadcasting nx 11 messages (n-number of CU)

  • Total amplifiers power of 1300 W

  • Cooperation with zone microphone ABT-DMS and ABT-M0x

  • TCP/IP network architecture

  • Up to 254 devices in the network with copper or fibre-optic wiring connection

MULTIVES FLEXIBLE TOPOLOGY

The main role of Voice Alarm System is the implementation of essential evacuation functions and communication of a threat occurrence. In normal conditions, Voice Alarm System fulfils the role of Public Address System and is able to broadcast music or public announcements using zone microphone or other connected to the system source of sound. Public Adress system for transport infrastructure enables broadcast of messages to selected platforms or other infrastructure of the train station in order to inform waiting passengers about any changes to the train schedule or any potential threat.

Integrated audio inputs in each Control Unit and each microphone allow connection of external sound sources and transmission of messages emanating from precedent external communication system.

Integrated message buffering function enables recording higher priority messages, broadcasting them through already engaged, by superior sources, loudspeakers and automatically playing them once the line becomes free.
