Harman Professional Solutions technologies, including JBL Professional VTX line arrays and Crown Audio I-Tech HD amplifiers, recently provided powerful sound reinforcement and uniform coverage for the AdvoCare National Success School 2015 at AT&T Stadium in Arlington, TX.
Multi Image Group (Boca Raton, FL) configured and installed the systems, which served approximately 24,000 people attending the training and motivational event hosted in September. AdvoCare is a provider of nutritional, weight-management, skin care and sports performance products.
“As corporate events go, it doesn’t get any bigger than this,” says Edward Gonzalez, director of audio services for Multi Image Group. “The setup was elaborate, with a stage that went lengthwise across the entire stadium floor with a raised platform, multiple large video screens and a sound and lighting truss that spanned the entire stage. It even had pyrotechnics that were launched from each side.”
The size and scope of both the stage and the stadium (which is home to the NFL’s Dallas Cowboys) called for a large-scale, high-output sound reinforcement approach marked by control. “The reverb times are massive,”Gonzalez notes. “We had to deliver concert-level SPL without everything turning into a washed-out blur, and the VTX line arrays worked perfectly. They deliver broad, yet focused, precise and stable horizontal coverage over long distances without exciting the reflective surfaces that could create excessive reverb.”
Multi Image Group deployed 96 VTX V20 line array loudspeakers arranged in four hangs of 24 each, plus two hangs of 10 VTX S25 subwoofers and a row of 12 G28 ground-stacked subwoofers. In addition, two hangs of six JBL VERTEC VT4886 subcompact line array loudspeakers provided side fill.
A dozen JBL F15 stage monitors delivered sound on stage to the presenters and performers, including contemporary Christian artist Michael W. Smith, The Sisters, the Aaron Loy Band, and a number of key AdvoCare executives.
Gonzalez states that there are practical advantages to using the VTX line arrays and subs, primarily the ease and speed with which the equipment can be moved, set up and dismantled. “I didn’t have a lot of truck space do to this show, and the VTX enclosures pack a lot of punch for such compact boxes,” he says. “Also, we were able to put the system up in a relatively short time, and we literally brought the whole rig down in 45 minutes at the end of the event.”
Crown I-Tech HD 4x3500HD amplifiers powered the V20 loudspeakers and S25 subwoofers, with I-Tech 12000HD amps driving the G28 subs. The crossover point for the ground-stacked G28 subs was set at 60Hz and the flown S25 subs were running from 120Hz to 60Hz. Gonzalez set up the S25 subs in cardioid configuration, which helped clean up low-frequency issues as well.
“The ability to precisely control the VTX system and the built-in preset tunings and flexible DSP of the Crown amps were huge advantages for this event,” explains Gonzalez, who also used JBL HiQnet Performance Manager to configure the system. “The VTX system worked wonderfully in a challenging acoustic environment, and the coverage was really outstanding.”
