Cardinals Feather Stadium with L-Acoustics

Home of the NFL’s Arizona Cardinals football team, the University of Phoenix Stadium opened a decade ago. Since then, pro audio has advanced considerably and with that in mind, this year saw the facility get a new house audio system before the start of the 2016 NFL season. Designed and specified by the Cardinals, the system consists primarily of flown L-Acoustics K2 arrays permanently installed in July by AV systems integrator Pro Sound & Video.

Phoenix, Arizona (November 15, 2016)—Home of the NFL’s Arizona Cardinals football team, the University of Phoenix Stadium opened a decade ago. Since then, pro audio has advanced considerably and with that in mind, this year saw the facility get a new house audio system before the start of the 2016 NFL season. Designed and specified by the Cardinals, the system consists primarily of flown L-Acoustics K2 arrays permanently installed in July by AV systems integrator Pro Sound & Video.

Over the past 10 years, the music playback needs of the stadium had expanded, requiring better low- and high-end reproduction, according to Jamie Gillespie, systems audio engineer for the Arizona Cardinals.

At the same time, both the stadium and the Cardinals were looking ahead, needing a lighter system to take into account the venue’s structural ratings for its massive truss system, which will be used for a center video cluster for NCAA Final Four games scheduled for 2017. “The K2 box weighs only 123 pounds, but it’s in the same class and has the power and throw of boxes that weigh twice as much,” said Gillespie.

Using L-Acoustics’ Soundvision 3D modeling software, the Cardinals were able to design a simpler system consisting of a total of 10 array hangs: eight arrays comprising 13 K2 enclosures each topped by four K1-SB subwoofers, and two end-zone hangs of nine K2 enclosures each, for a total of 122 K2 and 32 K1-SB.

Installed by AV integrator Pro Sound & Video, the system is rounded out with a dozen Arcs Wide enclosures used to fill the upper seats at the north end of the stadium and end zone, and eight X8 coaxial speakers to fill in a “shadow” area for seats used for special events under the main scoreboard.

A field fill system, using four hangs of four L-Acoustics Kara enclosures each, is hung behind four of the main arrays and used to cover the playing field for the Cardinals cheerleaders’ presentations and other on-field activities. A total of 81 LA8 amplified controllers power and process the entire system.

Despite the fact that this project represented one of the largest fixed installation projects in L-Acoustics’ history, the full system was on-site within four weeks of the official order. “The timeline to perform the installation by the first game was aggressive,” said Pro Sound & Video Executive Vice President David Shoemaker, who led the installation project. “Our immediate concern was whether L-Acoustics was able to deliver 122 K2 cabinets with just a few weeks until our deadline, which was the Copa America Games. We were absolutely thrilled when L-Acoustics was able to ship the entire order at once, giving us plenty of time to put in a temporary system for this world-class soccer event as well as ample time to prep the permanent rig for flying.”
