The VHD5 Constant Power Point Source System is the first major advancement in large scale concert sound reinforcement since the development of the Line Array. The VHD5 Constant Power Point Source System is a true feat of engineering. Over five years in development it brings the benefits of point source technology to large‑scale concert sound reinforcement. The system delivers audio over large areas with clarity and definition simply not achievable from the digitally processed line arrays that are so commonly used today. The system utilises highly advanced point source speaker design, extremely efficient power management amplifier technology and totally unique hybrid signal processing.
