Shure UHF-R tames RF interference in downtown L.A.

The Cathedral of Our Lady of the Angels stands as the spiritual home of the Roman Catholic archdiocese of Los Angeles. Despite a full audio update in 2001, increasing difficulty in finding viable wireless channels plagued the facility. While the systems installed at that time remain still function, the growing number of DTV stations in the RF-intensive downtown area grew old before their time.

Addressing the issue was the original installer, Bill Lightner of Santa Clarita-based AMS Systems. "The wireless systems were state-of-the-art when they were put in, but interference grew at an alarming rate," Lightner said. "While there is an amazing array of hardwired microphone locations located in the church, everyone uses wireless except for those in the choir loft. With the onslaught of digital television, it didn't take too long before frustrations were constant. It became a serious fight to keep the system running, and the church was clearly not winning."

To address the issue, AMT Systems selected eight channels of Shure UHF-R wireless. Along with its 2400 selectable frequencies over a 6MHz bandwidth, the system offers the benefits of Shure's Advanced Track Tuning filtering technology to maximize isolation from interference. Setup problems are handled through an automatic frequency selection feature with group scan.
