Electro-Voice MTS point-source loudspeaker system installed at Paul Brown Tiger Stadium

The 16,884-seat Paul Brown Tiger Stadium in Cleveland hosts Massillon Washington High School’s football games (Paul Brown played ball and later coached at that school) and is also used for Ohio’s high school playoffs and other major events. When it came time to upgrade the stadium’s sound system, the school invited multiple firms to participate in a loudspeaker shootout.

Cleveland’s NPI Audio Visual Solutions won the job with its demo of the new Electro-Voice MTS point-source loudspeaker system. Driven by Dynacord IPX10:4 amplifiers, the output (up to 155 dB peak) and long throw of the MTS loudspeakers, combined with their dispersion, enabled NPI’s three-zone design to deliver both the control and the intelligibility the venue was seeking.

“This was a three-way challenge for us”, says Dave Goff, the stadium’s Press Box & Media Manager who was also the project manager for the school. “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 with the EV MTS system.”

Designed specifically for large-scale applications, the MTS series combines four 15’’ woofers with dual coaxial mid/high compression drivers via a single waveguide. The cardioid version used at Paul Brown Tiger Stadium adds two more woofers for low-frequency directional control, creating a 40 x 30-degree dispersion to reduce unwanted spill.

At the 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.

Sam Avellone, NPI Director of Sales, designed the system, while Jason Brown managed the project, noting that Paul Brown Tiger Stadium was 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”, says Avellone.

The MTS loudspeakers at Paul Brown Tiger 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. 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 audio at the appropriate volume level to all three audio zones.
