Electronic Contracting Company (ECCO) of Lincoln, Nebraska recently implemented a comprehensive sound system at 15,147-seat Pinnacle Bank Arena, the new home of the University of Nebraska Cornhuskers men’s and women’s basketball teams.
Based on specifications developed under the direction of Kevin Day at Dallas AV consultancy Wrightson, Johnson, Haddon & Williams, the arena’s request for proposals (RFP) favored an integrated single-vendor solution. When the proposals were evaluated, the final selection for the arena’s PA were Electro-Voice line arrays made up of compact 3-way XLD281 elements.
In addition to the sound system, security and access equipment from EV’s parent company Bosch was also installed.
“Ten years ago there wasn’t much integration available for large arena systems, but these days we know that the technology is available,” says Chris Chavanu, who oversaw ECCO’s design-assist and installation responsibilities on the project. “So when we issued the RFP for a line array system with satellite speakers, we wanted everything from one source, not just the loudspeakers but also digital signal processing, power amplifiers and amplifier monitoring. That gives us a single company to deal with for communication, integration, support and service.”
The RFP process allowed for a half-dozen of the industry’s leading PA brands to submit proposals. “Most of them were eliminated from consideration,” Chavanu says, “because there were only two that were really able to meet the design guidelines completely by delivering a fully integrated system.”
In the end the Electro-Voice proposal was the choice, particularly fitting because the company has a local manufacturing and service presence right in Lincoln. Lin Buck of Electro-Voice sales, along with technical support engineers such as Stu Schatz, George Georgallis and Chris Aelits, worked closely with ECCO and WJHW to shepherd the installation from design to successful completion.
The core of the WJHW-designed system is six XLD281 arrays of eight elements each, flown around the central scoreboard. The XLD281’s 120-degree coverage pattern allows the short sides of the room to each be covered with a single array facing straight out. The four remaining arrays are each flown at a corner, angled such that the long sides of the room are each covered by a pair of arrays.
“The XLDs do a great job of providing coverage at long distances,” Chavanu says. “They’ve got the high directivity, high output and high intelligibility that we need. There is certainly more performance and value in the XLDs compared to similar-sized models from other brands.”
Power for the arrays is provided by a dozen Tour Grade series TG5l amplifiers “The Tour Grade amps are among the best-performing amps in our industry,” Chavanu states. “They are incredibly stable, very high output, very high efficiency and they sound amazing.”
Each TG5 is equipped with an optional RCM-28 – the latest generation remote-control DSP module from EV. RCM-28 is a dual-channel DSP and control module for Tour Grade amps that supports Bosch’s OMNEO media networking architecture, which combines Dante audio networking with the OCA control networking platform.
Amplifiers with RCM-28 modules installed can be integrated into OMNEO networks that operate over standard Ethernet and can interoperate with Dante and OCA enabled products from any manufacturer. With an RCM-28 module installed, network, audio, and system parameters can be completely supervised and controlled remotely through IRIS-Net software.
