Salt Lake City (May 21, 2007)–Capable of seating an audience of more than 21,000, Salt Lake City’s LDS Conference Center was first opened by the Church of Jesus Christ of Latter-day Saints (LDS) in the spring of 2000. LDS Sound Engineer Trent Walker and others were never happy about the sound, however, so Salt Lake City-based Poll Sound, led by general manager and lead sound system designer Deward Timothy, was tasked with creating a new system that would do the room justice.
An L-Acoustics dV-Dosc PA hangs in the LDS Conference Center in Salt Lake City.There were many challenges to overcome in an acoustic environment that is large enough to hold a Boeing 747. The room has a rounded back wall, so making adjustments to the system to minimize reflections was no easy feat. The left and right PA speaker positions are 120 feet apart – the width of the stage – making it difficult to create an image.
In the end, the decision was made to go with an L-Acoustics dV-Dosc PA. The front-of-house system is set up to be an LCR system with 18 dV-Dosc cabinets flown per side and six dV-Subs for extended low-frequency reinforcement. The foldback system for the choir and orchestra runs 16 discreet mixes, and monitors deployed are combination of L-Acoustics MTD112b and MTD108a enclosures.
When it was time for tuning, Timothy found, “We loaded the L-Acoustics preset file for our processor and, to be perfectly frank, we didn’t change it in the least. We did some minor tuning after the fact, but their factory preset was almost right on.”
The first show in the main hall with the new dV-Dosc system was the American Forces Radio and Television Service’s Christmas broadcast to the troops, which featured contemporary Christian artist Sandi Patti performing with the Mormon Tabernacle Choir and Orchestra. Walker remarked, “The goal was to ensure that we had coverage and that what is heard is the purity of the music, not the speakers. We are now getting a stereo image in a large portion of the room and that has made a huge difference for our audience. We were thrilled and so excited that we went with the dV-Dosc.”
