Paul Brown Tiger Stadium, a 16,884-capacity facility that hosts football games and other events at Massillon Washington High School in Ohio, now has upgraded sound reinforcement capability with the installation of a new three-zone system headed by Electro-Voice MTS point source loudspeakers driven by Dynacord IPX10:4 amplifiers.
The project was awarded to Cleveland’s NPi Audio Visual Solutions following a loudspeaker evaluation process with the client. Dave Goff, the stadium’s press box & media manager, handled project manager duties for the school.
“This was a three-way challenge for us,” Goff notes. “The home stands feature an extended roof line that creates intelligibility issues, while the visitor stands require only direct sound. In addition, the team wants the sound on the field to be loud pregame and halftime to pump them up, but we want levels in the stands to be conversational. NPi addressed all these issues effectively with the EV MTS system.”
Designed specifically for large-scale applications, MTS series loudspeakers combine four 15-inch woofers with dual coaxial mid/high compression drivers via a single waveguide in a design focused on cohesive output with strong bass response. The cardioid version used in this design adds two more woofers for low-frequency directional control, creating 40 x 30-degree dispersion that reduces unwanted spill.
At Paul Brown Tiger Stadium, three MTS-6154-43 boxes are secured by custom-designed platforms atop the video scoreboard, with the outside units angled toward the grandstands. This creates separate, controlled audio zones for on-field sound as well as the home and visitor grandstands.
NPi director of sales Sam Avellone designed the system while Jason Brown managed the project for the integrator, noting that it marks the first major installation of MTS in the U.S. “We worked with EASE models and our EV rep, Jason Jacquemain, to finalize the design. Jason was also instrumental in scheduling the MTS demo at the stadium,” Avellone says. “What I love about MTS is getting both an effective point-source system and the ability to direct and control the sound. When we did the demo, using just one MTS speaker, it was stunning. We walked the whole stadium, top to bottom, and were blown away by the coverage and clarity. And of course, the final installation is even better. We’re very proud of it.”
The MTS loudspeakers at the stadium are fully weatherized (partially weatherized versions are also available) and all MTS models are IP55-certified for protection against dust and water ingress. Each of the three boxes is powered by one Dynacord IPX10:4 amplifier. Equipped with OMNEO IP networking architecture enabling Dante and OCA/AES70, IPX models are stated to provide 96 kHz DSP with low latency and a high signal-to-noise ratio, along with technologies for added energy efficiency and system protection. The amplifier rack is housed in a converted ticket booth, allowing the system to work with the Q-SYS front end in the press box as part of the stadium’s Dante network.
To ensure proper operation of the system, NPi provided a simple tablet interface that allows the stadium’s AV team to deliver clear, full-range audio at the appropriate volume level to all three audio zones. “It’s a night-and-day difference from our old system,” says David Wagner, scoreboard operations manager. “What amazed me was the system’s ability to control levels while actually improving clarity in our home stands, especially under the roof. This new EV system really makes the fan experience more enjoyable, which was really the whole point.”
