NASHVILLE’S LP FIELD
Company: One Systems Location: Nashville, USA
One Systems recently had its speakers installed at Nashville’s LP Field as part of a complete renovation of the stadium’s sound and video system. LP Field is the 69,143-seat stadium that is home to Nashville’s NFL Titans, the Music City Bowl and various concerts that include the annual CMA Music Festival. Located on 105 acres across the Cumberland River from downtown Nashville, LP Field opened in 1999 and is owned by the Metropolitan Government of Nashville and Davidson County. During last summer, LP Field underwent a series of renovations including the installation of two large HD video displays measuring 157ft by 54ft located on both the north and south ends of the stadium, as well as a new distributed sound system. LP Field’s reconfigured sound system includes 166 One Systems speak- ers, 146 106IM/70’s, eight 108IM/70’s and 12 112IM/70’s. All of the speakers were installed using One Systems’ stainless steel U-Brackets. The stadium’s east and west concourses have overhead cover, but are open air. The north concourse of the stadium is completely open. As such, all the speakers are exposed to a mixture of heat, cold, wind and moisture throughout the year. The 106IM/70’s
WILLIAM D. MULLINS MEMORIAL CENTER ARENA
Company: QSC Audio Location: Amherst, USA
The William D. Mullins Memorial Center Arena is home to the University of Massachusetts at Amherst’s Minutemen basketball and ice hockey as well as the Minutewomen basketball teams. Located on the UMass campus, the 10,500-seat Mullins Center Arena recently unveiled the replacement for its 20-year-old installed PA system. The new system includes a QSC Audio ILA System comprising 72 WL2082-i line array elements and 12 WL118-sw subwoofers driven by 22 Pow- erLight 3 Series PL340 amplifiers, all under the control of two Q-Sys Core 250i units with a Q-Sys I/O Frame. The Mullins Center’s new sound system was designed by Acentech and installed by North American Theatrix (NAT), working with McPhee Electric. Consultant in Acentech’s Audiovisual Systems Group, Scott Jordan said: “The hunt was out to find a loudspeaker that would give us the necessary wide vertical coverage required, keep the weight in check, and most importantly fit within our budget. At this point I took a look at the QSC ILA product, having been familiar other QSC products prior. Once the loudspeakers were put in the model in EASE, it was clear these enclosures would do what I needed them to do. The price point on these also allowed us to add those additional enclosures while staying well within our original budget.” Pat Nelson, Director of Projects at NAT also worked up an EASE Focus model, in consultation with QSC Audio, and confirmed Jordan’s findings. Both predictions were right on the money. “Probably the most rewarding part of this project was when we first fired up the QSC system - it sounded amazing right out of the box,” reported Pat. The ILA System is distributed in eight arrays around the sports arena, three on each side and one in each end zone, as well as three arrays covering the floor.

and 108IM/70’s are installed on the stadium’s main concourses surrounding its 60 concession areas. While the 112IM/70’s are installed adjacent to the stadium’s entrances. The system is used for live broadcasts during games, as well as all announcements from the main PA. One Systems was recommended to LP Field’s management by one of the contractors who bid on the project. Management was familiar with One Systems based on a demonstration they heard in 2011 and WJHW of Dallas, Texas, the consultant for the project, approved the inclusion of One Systems speakers into the project. The audio / video contract for the project was awarded to AVI / SPL of Columbia, MD, who supervised the installation and worked with Amprite, a local electrical contactor and installer. “LP Field is a prime example of a multi-use, large-scale outdoor sports and entertainment venue where One Systems speakers work especially well”, said One System President, Doug MacCallum. “It is always exciting to be a part of such high-profile venues.”

As for intelligibility, he said: “It’s a concrete hockey rink and we’re getting STI [speech transmission index] levels of 0.54 or better - that’s considered good to very good, and well within what we expected. There is no shortage of output either. We achieved 112dB, and we still had headroom in the system.” The new system also includes a Yamaha LS932 digital mixing console fitted with CobraNet output cards feeding two QSC Q-Sys Core 250i processors installed 400ft away in the gridwork high above the floor alongside the QSC PL340 amplifi- ers. Greg Downing at NAT was instrumental in doing all of the programming for the system with Q-Sys. “The Q-Sys feeds are sent to the amplifiers through DataPort, so everything is digital all the way to the amps,” said Pat. “We’ve used the Q-Sys Core 1000 in other arenas in the past, but this was our first time using the Core 250i.” “We have an I/O Frame down in an existing amp room that’s providing a couple of local inputs and outputs,” added Scott. “There are still some legacy audio systems in place in Mullins for the concourse and other public areas we didn’t change, and it was important to have a DSP system in place that could expand as necessary to allow for those eventual upgrades.”
