Progressive approach to technology

Since our founding in 1989 as an electronic design consultancy, ASL has been at the forefront of innovation in the audio industry. In 1999, we made our mark in the voice alarm market with our technology-leading evacuation systems for London Underground, and from there, we quickly became a key supplier to the transport industry.

Today, we continue to design and manufacture cutting-edge audio products for customers worldwide, catering to both emergency and non-emergency applications. Our expertise and commitment to excellence are evident in every product we create, whether it’s a voice alarm system for a train station or an audio experience for a stadium.
