Miami, FL (March 24, 2017)—Miami’s Hard Rock Stadium is home to the NFL’s Miami Dolphins, and now, to a massive audio system of more than 3,000 loudspeakers, designed and installed by Diversified Systems in collaboration with the Bosch/Electro-Voice team
The facility just finished a three-year renovation that included a roof and video displays. While that makes for a more modern facility, however, taking away the open-air design means that crowd noise is higher due to reflections, making coverage critical, both in terms of SPL and frequency response.
The installation delivers sound via 186 XLCi-127DVX line array elements, weatherized and integrated into custom-engineered frames to withstand extreme storm and wind conditions. These are augmented by EVF-1122S front-loaded loudspeakers and EVH-1152D long-throw loudspeakers to cover hard-to-reach zones like corner seating areas. In addition, 48 dual 18-inch subwoofers, custom designed for the project, add a bass element.
To ensure even coverage throughout all seating areas, EASE modeling and intelligibility plots were critical tools in selecting the appropriate loudspeakers and their placement. Two Electro-Voice NetMax N8000 digital matrix controllers allowed the integration team to apply FIR filtering to optimize loudspeakers.
The sound system is also used for mass notification of life safety information coverage in luxury suites, concourses, restrooms, offices, and all public areas throughout the stadium. This task required approximately 1,800 Electro-Voice ZX1i indoor/outdoor loudspeakers and more than 1,000 EVID ceiling-mounted designs.
Despite the massive side of the project, the installation met budget and timing requirements and is expected to serve Dolphins fans for years to come.
