THE CHALLENGE
Most audio amplifier development today focuses only on sound quality, while factors such as efficiency, size and reliability are overlooked. Current solutions with advanced features often rely on separate processors, which significantly increase the costs and complexity of the system. This directly depends on the reliability of public address (PA) systems. Many audio amplifiers that are installed in these systems usually depend on wired communication, making it difficult to detect failures or to monitor the system performance.
WHY IT MATTERS
Research about PA system work at bus and train stations in Europe shows 60% of passengers report issues. In order to improve passenger informing, 70% of airports plan full system upgrades by 2030. Upgrading audio systems can directly impact safety, travel efficiency, and the economy.
OUR SOLUTION
Our digital Class-D amplifier design reduces both energy consumption and device size compared to conventional amplifier classes. By integrating digital sound quality control on an integrated processor and using innovative GaN transistors, we overcome the increased distortion which is often linked to this amplifier type. Providing the possibility of wireless communication, our design combines all key hardware and software functionalities into a single compact and accessible device. The implementation of an integrated digital processor enables flexibility, allowing the same device to be adapted through software to deliver specific value across a wide range of applications.
