Built in 1963, the cathedral is the home church for the Roman Catholic Diocese of Las Vegas. It serves local families and Las Vegas tourists with its daily masses and other services. Its attractive “A-frame” design features beautiful stained glass windows and polished tile floors. However, combined with a 66-foot height, these features result in a high reverberation time which benefits the choir and organ but detracts from speech intelligibility.
The cathedral’s older sound system was unable to provide acceptable voice quality in this reverberant environment. Guardian Angel’s new system consists of two Community ENT212s on each side of the sanctuary and one on each side of the balcony for a total of six columns. The loudspeakers are progressively delayed to synchronize arrival times throughout the sanctuary.
