Special Event Services (SES) of Mocksville, NC was recently contracted to supply a major sound system for the LCMS (The Lutheran Church – Missouri Synod) for church’s triennial Youth Gathering in Houston (Texas) across a number of venues. The system had to be capable of delivering live music and, most importantly, perfectly intelligible speech to a very large area containing around 20,000 participants.
With its roots going all the way back to 1847, the LCMS (The Lutheran Church – Missouri Synod) is a traditional, confessional Lutheran denomination with 1.8 million members, making it the second-largest Lutheran body in the United States.
The church’s triennial Youth Gathering is a five-day meeting which has been staged since 1980, providing an opportunity for thousands of young adults to come together as a community of God’s people to learn about the Christian faith and their Lutheran identity. The 2022 event was held in Houston (Texas) across a number of venues, the largest being Minute Maid Park, a baseball stadium which is normally home to the Houston Astros.
A long-time user of Outline loudspeaker systems and no strangers to this kind of application, SES deployed part of its GTO inventory to cover the stadium. Four 15-deep arrays were flown from two ground-support towers close to first and third bases, configured L/R/LL/RR, with low frequency reinforcement provided by 18 LAB 21 Outline infra-subwoofers.
Because no participants were permitted on the field itself, the sound system needed to reach people up to around 300’ (91m) away, in the stands. Jason Farah from Special Event Services commented: “The configuration of the PA allowed me to deploy the system with a sufficient number of tight angles at the top of the array to provide excellent coupling and thus the horsepower necessary to reach that long throw.
“The Smaart traces taken initially at the various seating levels (Levels 100 through 400) were remarkably similar – they basically overlaid each other, demonstrating the inherent performance of the GTO system. While I did have the ability to EQ the individual zones within the array (to even out the possible response curves in the various levels), that was largely unnecessary: the only zone EQ needed was a small HF shelf I put on the bottom three cabinets to reduce the relative ‘sizzle’ in that nearest zone. That single filter was all that was needed to make all the zones’ response curves lay atop each other. Once that was done, I could apply the overall array tuning, knowing that the experience was the same throughout the entire listening space.”
The system relied on a pair of Outline Newton processors, one for each tower: “The Newtons performed flawlessly and the superior WFIR filtering technology made tuning the system effortless,” said Farah. “The result was a full, smooth, totally natural sound at every seat in the stadium. My audio systems assistant, Andrew Steelman, had the opportunity to walk up to the top of the 400-section to the rearmost seats. He reported that it sounded every bit as good there as anywhere in the stadium.”
Barry Dixon mixed FOH at the stadium and he clearly enjoyed his work on this occasion: “From a front of house mix perspective, I was completely impressed on many levels by the Outline GTO system.
“This was an extremely difficult application for any PA. Not only did it have to hang from towers as there was no roof or structure, it was blowing into open mics on three stages and it was hundreds of feet from the audience. It was mission critical to tie the audience to the event by effectively reaching them from an audio perspective with the PA system.
“The overall cohesiveness of the system across the spectrum was very impressive even at the extreme distance to the crowd – it gave me the impression that there was a single full spectrum point source at the right and left towers. There was no sense of ever struggling with the cracks between awkward crossover points or between the different transducers in the individual loudspeakers. The system also presented vocals and speech to the audience very effectively, with emphasis on the word ‘presented’ as one almost got the sense of having the mix served to them. At 300 feet away, it did not sound like one had to reach out and have to work to perceive the spoken word or vocal.
“The subs were astoundingly tight and musical. What do I mean by tight? One example is, when I added a touch of 45Hz to the kick, what I got was a sense of movement in the sternum. In other cases with ‘looser’ subs, adding this frequency just muddies the very low end. So what do I mean by musical? I suppose I’ll summarise that by using more subjective terms like it was ‘warm’ and ‘enveloping’ as opposed to ‘incongruent’ and ‘muddy’.”
Jason Farah concluded: “While we deploy GTO often, it never ceases to amaze me with the results we get. Its power, fidelity, and unsurpassed stereo imaging makes it my system of choice. When it comes to large-format events, nothing compares.”
