Del Valle High School football stadium upgraded with Dynacord/Electro-Voice

Southwest Building Systems (SBS), specialists in outdoor sound systems and big-screen video systems, upgraded the audio system at Del Valle High School’s 4400-capacity Veterans Memorial Stadium. Del Valle ISD is located in suburban Austin, Texas.


SBS Development Manager Brent Thornhill chose the new Dynacord MXE5 matrix mix engine to control all aspects of the system, which includes weather-resistant loudspeakers from Electro-Voice powered by Dynacord amplifiers. Dynacord’s Sonicue sound system software was used to set up and fine-tune the main PA.


Flanking the large video scoreboard beyond the end zone are two arrays of eight XLD291 line-array loudspeakers, each covering the bleachers along one sideline. In addition, a set of four Electro-Voice X12i-128 dual-18” subwoofers is mounted on a platform in cardioid configuration, focusing low-frequency coverage across the entire stadium.


All the end-zone loudspeakers are fully weatherized, with an IP55 rating against dust and water. Three Dynacord IPX10:4 amps power the arrays and an IPX20:4 handles the subwoofer stack. The amplifiers are rack-mounted in the video control room with the network switches and the MXE5. The new Dynacord TPC-1 touch panel controller at Del Valle stadium is located in the press box, providing access to change the system’s power status, presets, input sources and gains.


The stadium announcer’s desk is equipped with an Electro-Voice PC Desktop-12 gooseneck microphone from the PolarChoice series. Two Electro-Voice RE3 wireless systems are deployed, one with a switch-enabled headworn referee system and the other a handheld mic with ND86 capsule for speeches and vocals.


To meet ADA accessibility requirements, a Telex SoundMate assistive listening system was specified, equipped with rechargeable bodypacks and a choice of SCB-1 earbuds or the NLS4, an inductive neck loop for use with hearing aids. The stadium’s video control room sports an Evid-C6.2 ceiling speaker as a confidence monitor, and the production team uses an RTS BTR-800 intercom system.
