This case study details the audio system upgrade at Ascot Racecourse, located in Perth, Australia. The objective was to enhance digital audio clarity and flexibility while maintaining ease of operation. The solution implemented was the Tesira DSP platform from Biamp, which streamlined audio processing and control, reducing the need for multiple technicians. The system's flexibility allowed for user-friendly operation across various audio zones, including grandstands and outdoor areas. The intuitive Tesira Canvas software enabled staff to manage audio settings with ease, significantly reducing the learning curve. The installation of TEC-1 wall-mounted control panels provided straightforward zone-specific control for staff and visiting technicians. Additionally, the system offered configurable paging capabilities, allowing for urgent announcements across the venue. The upgrade resulted in exceptional audio zoning flexibility and improved speech intelligibility, ensuring that all race calls and announcements are heard clearly, contributing to an enhanced atmosphere at the racecourse.
