Plus 4 Audio 25th Anniversary

Celebrating 25 years at the forefront of the broadcast and events audio world​

2026 marks 25 years of audio design in the broadcast and events industry, and a special thanks needs to go to all our employees, freelancers, designers, producers and special clients that have made Plus 4 Audio the company that it is.

Having started early on in the reality TV and entertainment broadcast industries, Stewart and Plus 4 stamped their mark as the broadcast audio supplier of choice. Looking to redefine the way audio in TV was handled, Stewart led the way in design and equipment deployment.

In 2025 Plus 4 joined the ranks of the Clair Group, denoting a major step forward and with the global reach of the Group forging the way forward, the future looks positive and exciting.

Plus 4 Audio continues to use their resources to continue to grow using the well established formula, alongside innovation and creativity, that has seen the company deliver successful shows since 2001.
