Easy Control

ASL’s PA solutions provide operators with freedom to control the music selection and control the volume via wall panels, PC GUIs or third party controllers.

Sophisticated audio routing combined with modular amplifiers with programmable power ratings enables efficient delivery of audio into spaces with changing requirements for different events and uses.

Professional Audio

ASL’s PA systems feature a novel power amplifier and power supply design, which combines low physical size with high efficiency, and with the excellent audio performance expected from a professional audio system – wide bandwidth, low noise and  low distortion.

Dante connectivity enables ASL systems to be integrated with third party equipment to create sophisticated systems, including ASL’s high quality audio and voice alarm functionality.

Scalable and Flexible

ASL’s PA solutions cater for expansive public spaces with ease, using built-in fibre-optic IP networking or Dante connectivity, for fast and reliable audio distribution across many floors, and between buildings.

As commercial sites are constantly changing environments, ASL systems are designed with full flexibility in mind, offering easy expansion options to accommodate newly created spaces.

Multilingual Support

ASL’s iVENCS Control System provides intelligent artificial messaging for hotels and other hospitality venues. The iVENCS GUI can be translated into different languages, and announcements can be stored and played in multiple languages, including text to speech.

ASL’s microphone user interface is also available in a number of languages, and new languages can be added as required.

Challenging Acoustics and Noisy Enviroments

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.

Entertainment and Safety

ASL’s professional audio PAVA systems provide high quality background music, to ensure a relaxing and consistent customer experience, as well as providing the highest standards of safety.

Local control of music source and volume allows tenanted areas to create their own ambience. without the need for a separate system, and without loss of control to the site staff.

Low Operational Costs

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.

Networking and Audio Distribution

Hotels and hospitality sites can cover large areas, often with equipment room nodes spaced widely apart. ASL’s IP networking capability allows equipment installed in remote locations to operate together as a single system, using dedicated failure-resistant redundant copper or fibre IP networking.

Easy Migration to ASL

ASL understands that PA migration come with risks and often happen in stages. ASL systems can readily work with existing third-party PA systems either during a changeover phase or on a permanent basis to manage risk in a predictable way.

Cyber Security

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 customers.

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.

PA Wall Controller

ASL’s WMC01 Wall Mount PA Controller is used to choose from a list of audio sources and to adjust their broadcast volume levels.

The controller is typically installed in restaurants, meeting rooms and hotel lobbies, to allow users to select from a list of different music channels and to adjust the volume.

Building Management

ASL’s PAVA systems can be combined with ASL’s award-winning iVENCS Control System for comprehensive building management. The iVENCS control system is normally run from dual-redundant servers, and allows users at multiple workstations to monitor and control a multitude of subsystems around the building, including fire detection and safety systems, CCTV, access control, intruder detection, information and advertising displays, telecoms, network monitoring and more.


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

iVENCS - Integrated Site 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 site 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 site 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 site. 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 or groups of floors, with seamless viewing from any position. This avoids other system’s need to split the building 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 building’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

Site 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 site, 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.
