Community audio system for US school stadium

Community audio system for US school stadium

Cardinal O’Hara, a Catholic High School in Springfield, Pennsylvania, has upgraded its American football stadium by replacing an outdated paging horn system with a new audio system using Community R-Series Loudspeakers. As the only Philadelphia Catholic League school with a home football stadium on school premises, Cardinal O’Hara’s Lions Stadium has large home and visitors bleachers, an enclosed press box, an artificial turf field and a modern track.

Designed and installed by Tony Albano of Naamans Creek AV in Avondale, Pennsylvania, the system uses three Community R.5 loudspeakers and one Community R.25 loudspeaker. Two of the R.5s are installed at the outside corners of the press box to cover the left and right sections of the home bleachers and a third is installed on a lighting pole behind the press box to cover the visitors’ bleachers. The single R.25 covers the centre section of the home bleachers from the front of the press box. Albano says he could have installed all three of the R.5s on the lighting pole but he wanted to avoid high SPLs on top of the press box where the videographers stand. His design covers all of the audience areas well including a standing area in front of the home bleachers.

For electronics, Albano chose a Rolls mixer and a CTS 4-channel amplifier. He installed a push-to-talk mic in the press box, provided a wireless mic for field announcements and installed a 3.5mm input for portable music players. A Community dSPEC DSP provides loudspeaker management and system equalization. Albano added a switch that reprograms the DSP to turn off the R.5 covering the visitor’s bleachers. This minimises feedback and delay issues during field announcing. The entire electronics system was installed in a portable electronics rack which can be removed between events for security.

Albano says Cardinal O’Hara’s Lions fans love the new audio system. The sound level is very even throughout the audience areas, announcements are clear and music sounds great.
