Dallas Cowboys expand Electro-Voice line array installation at AT&T Stadium

• AT&T Stadium adds XLC line array loudspeakers and TG series amps to upgrade intelligibility for upper seating areas
• NetMax N8000 digital matrix controllers enable seamless scalability for integration of added arrays
• Pro Media Audio Video, WJHW and Electro-Voice team with Dallas Cowboys to keep massive stadium system sounding like new

When the Dallas Cowboys opened AT&T Stadium in 2009, it boasted the world’s largest Electro-Voice sound system in a permanent installation, including over 240 line-array loudspeakers from the X-Line family. The design team, spearheaded by Kevin Day of WJHW, selected EV systems for their audio quality, reliability and depth of control provided by the IRIS-Net processing and monitoring platform. After enthusiastic approval from team owner Jerry Jones, Pro Media Audio Video was enlisted to help coordinate the challenging installation.

Fast-forward to 2019. Noting that the many touring concert acts coming through the world’s largest domed stadium simply do not carry enough PA to provide adequate coverage for the upper seating areas, the audio team decided to take advantage of EV’s scalability to address the challenge.

“We're always working to improve the fan experience for all events, not just on game days,” says Gary French, Audio Engineer in Charge for the Dallas Cowboys. “Most concert tours augment their traveling systems with our EV arrays as the delay system for the upper levels. We decided a little extra coverage would be a big upgrade for those events.”

The Cowboys’ audio team worked with system programmer Richard Bratcher, along with original design and installation partners including Kevin Day of WJHW, head engineer Demetrius Palavos and COO Ted Leamy of Pro Media Audio Video, and the Electro-Voice engineering team. Together, they determined that the 14 XLCi127DVX (compact three-way) delay systems covering the upper level could be scaled up to produce smoother coverage with improved intelligibility.

Ted Leamy of ProMedia Audio Video reports that the upgrade went very smoothly. “This project is a great example of using real-world experience hand-in-hand with predictive computer models to improve a system,” he says. “By listening to the customer, we find ways to improve a system that already sounds great. We’re all extraordinarily pleased at the increased intelligibility we achieved.”

The upgrade includes two added XLC arrays on each side of the stadium, plus the addition of one more loudspeaker element to the 14 existing arrays serving the 400 level, for a total of 54 added boxes. The system is also bolstered with 20 additional Electro-Voice TG series amplifiers, each equipped with RCM-26 remote control DSP modules. One additional NetMax N8000 digital matrix controller was also added. The IRIS-Net platform’s proven stability and scalability was a key factor in the expansion.

“Having used this system for every type of event, it’s amazing how flexible it is,” adds Gary French. “We’ve had no real issues with it this whole time, and Electro-Voice is there for us whenever we decide to tweak something. After 10 years, everything still looks and sounds new and I’ve been really happy with it. You can’t ask for more than that.”
