Stadia

ASL is just the ticket

Stadia and arenas have extremely demanding audio requirements; they are large, require high sound pressure levels, but with high quality audio, and have different operation modes for different events, such as on match and non-match days.

ASL has considerable experience in the stadium industry, and has delivered EN 54 certified systems which perform to the highest audio standards. Our close collaborations with major power amplifier manufacturers and system integrators enable us to unify the sound system for both comfort and safety, to enhance the overall customer experience, and to simplify system delivery and ongoing maintenance.

  • Fire and emergency staff can protect
  • DJs and hospitality staff can entertain

Installation and Operational Challenges

Modern arenas and stadia perform multiple roles, whether indoors or outdoors, and consequently pose considerable security, installation and operational challenges. The requirement for a unified and reliable safety and entertainment system is more essential than ever.

Combined EN 54 & Dante™

Stadia have traditionally used two separate audio systems; one for the main arena – typically a high power line-array system or similar – and a separate EN 54 compliant voice evacuation system for the concourses, bars, and back of house.

Using Dante combined with ASL’s SecureLoop network, ASL meets all the  requirements with a single unified system solution.

Eliminate Downtime

ASL’s decentralized architecture, built-in redundancy and automatic hot standby systems provide high availability, to keep the audio in your stadium operational. However, if something does go wrong, ASL’s modular hot-swap amplifier cards even allow maintenance during an event, while ASL’s ‘hardware bypass’ function enables local emergency microphones to operate even if the router’s CPU and DSP processing have failed.

Challenges

With more than 25 years experience of designing and developing Public Address and Voice Alarm products for critical infrastructure applications, ASL offers peace of mind. You can rely on ASL solutions to work, and to continue working, throughout the life of the system.

Our PAVA systems will deliver the message to where it needs to be heard, when it needs to be heard.

ASL's powerful DSP Digital Signal Processing provides sophisticated EQ Equalisation Controls, while DANS Dynamic Ambient Noise Sensors and continuous noise compensation technology enables broadcast intelligibility to be optimised to cater for varying real-time ambient noise levels.

Stadiums cover large areas, often with equipment room nodes spaced widely apart at opposite sides or ends of the Stadium. ASL’s IP networking capability and Dante both allow equipment installed in remote locations to operate together as a single system, using dedicated failure-resistant redundant copper or fibre IP networking.

Stadiums and arenas are ever-changing and expanding. ASL’s future-proof audio-over-IP architecture and modular design simplifies installation, and allows systems to grow and adapt as your needs change.

Proven reliability: With ASL's first generation systems still installed and running. Long, reliable, product life means lower ownership costs and low whole life costs.

Efficient power supplies and amplifiers reduces lifetime energy usage, and reduces equipment room cooling requirements.

To secure the PAVA system and to ensure uninterrupted operation: ASL’s solution supports full encryption and authentication of control and audio data, including 2Factor authentication for tools and configuration management.

Sector-Specific Products

ASL combines close liaison with our customers and end users, technological innovation, and the comprehensive knowledge of our experienced team to tailor our products to industry-specific requirements, and to set new standards with our dedicated industry specific products. A few key examples are referenced below. All of which were designed to improve the experience of your staff and visitors.

Dynamic Volume Control

ASL’s DANS01 dynamic ambient noise sensor enables the PA volume level to be automatically adjusted in real time. These noise sensors feed audio from their PA zone back to the ASL router, where the DSP digital signal processor separates any broadcast audio from the ambient noise. Thus, the volume can be controlled in response to ambient noise, even during announcements.

This ensures the PA audio is at a comfortable level and intelligible, even if the noise level varies widely during a broadcast.

Dante™ & EN54 Integration

ASL’s hybrid EN 54 and Dante audio system provides EN 54-16 compliant evacuation coupled with the flexibility, programmability and functionality of a Dante entertainment system.

ASL’s integrated Dante audio solution allows up to 32 audio sources to be sent over high quality uncompressed, digital media channels, with near-zero latency and exceptional synchronization across large decentralised systems.

When you consider the advantages of hybrid EN 54 / Dante solutions, more and more use cases come to mind.

High Power Amplifiers

ASL’s D500 500W amplifier card uses a novel design which combines the excellent audio performance of a professional audio system – such as low noise and low distortion – with the high efficiency and low quiescent consumption needed for a battery-backed Life Safety System. This reduces lifetime energy usage, and reduces equipment room cooling requirements.

Where even more power is required, ASL’s Dante integration enables third party professional audio amplifiers to be used in conjunction with the ASL amplification and control equipment.

iVENCS

The iVENCS Control Software is a truly open and intuitive integrated management platform

iVENCS - Integrated Stadium Control

ASL’s enhanced iVENCS Site Management System provides integrated distributed control

The iVENCS Control System has recently received an entire technology and GUI upgrade, consolidating its place at the forefront of the management of the public in large sites.

iVENCS is a truly open and intuitive integrated management platform which offers robust control, monitoring and incident analysis across all safety, security and communications subsystems. Plus, in addition to the standard subsystems and functions, iVENCS provides the flexibility needed to provide custom integrations with industry-specific  and site-specific equipment.

iVENCS provides the ability to integrate and simplify the control of all aspects of stadium management, with powerful and simple to use telecoms and security controls. System control and monitoring can be provided at a central control room and at distributed workstations, all running from multiple redundant servers. Customised staff information screens and stadium overview video walls can be provided, which combine alarm and status reporting with CCTV views.

The award-winning and unique true 3D GUI can show an accurate, fully scaled model of the whole stadium. The model’s pan, tilt, rotate and zoom controls allow the user to move the viewpoint at will, to any part of the 3D model and to any floor, with seamless viewing from any position. This avoids other system’s need to split the stadium GUI into multiple small 2D maps and false-3D building plans, requiring the operators to switch between many different maps in order to operate the stadium’s equipment.

Key Features:

  • Award-winning 3D or traditional 2D GUI
  • System schematics and dedicated subsystem controls
  • Consistent and simple to use functionality, for multiple systems
  • Industry and custom site-specific integrations
  • Ability to provide advertising content onto displays
  • Remote Condition Monitoring
  • Distributed processing with multi-site redundancy
  • Modular system architecture; easily expandable
  • Cross-platform support
  • No ongoing license costs

Stadium operators need to monitor an ever-increasing number of subsystems, from fire detection to CCTV, PA to information displays, access control to intruder detection, and far more. ASL’s award-winning iVENCS Control System empowers both managers and operators to simultaneously control a multitude of systems. Via the intuitive 3D user interface, staff can keep a constant eye on the public and on the status of equipment around the stadium, are able to remotely control devices, and be alerted to any faults and devices that are in need of investigation.

iVENCS makes public and staff communications easier to manage, through auto-scheduled announcements, intelligent message builders, multi-lingual messaging, and information displays.
