When AVA first met with the staff from St. Matthew’s Church, there was no consideration of sanctuary upgrades. They were simply looking for an installation of A/V in a few classrooms. Prior to leaving, we stopped in the sanctuary ‘just to take a look.’ We became aware that the reason we stopped in was actually, ‘just to take a listen.’ With tile floors, wooden pews/ceiling, multiple speaker locations, and no acoustic treatment – it became apparent why speech was almost unintelligible. We provided some recommendations/suggestions, and needless to say, the sanctuary soon became #1 priority.
AVA supplied an EASE analysis graphic rendering of the room which showed acoustic levels and problem locations. Using calculations, software, acoustic treatments, and strategically placed speakers, AVA was able to significantly reduce echo and make a phenomenal difference in the intelligibility of vocals and the spoken word. The RT (reverberation time) prior to treatment was in excess of 12 seconds. Post-treatment reduced the RT time to slightly above (2) seconds; a six-fold correction. Noise level in the sanctuary was reduced by about 35%.
Acoustic treatment was provided by Sound Management Group who strategically placed (76) panels of Sound Delete Acoustic Wall Treatment along the side and rear walls. All existing Audio Technica Microphones were used in conjunction with the addition of (4) Beyerdynamic hanging choir mics, (2) Renkus Heinz PNX82/9 speakers (custom painted to match wall colors), and Crown CTS4200 Amplifier. All audio processing, distribution, and equalization is achieved through existing BiAmp Audia Processor.
To allow simplified operation of the system, AVA configured a custom Crestron Control System which allows source selection, volume control, and media control through an Apple iPad anywhere in the facility. A BiAmp RED1 allows for volume control at the choir location.
“I can’t believe how good AVA has made our church sound! We cannot thank you enough.” – Matt, Choir Director
