LDS Conference Center Makes Sound Improvements with L-Acoustics

Poll Sound enhances audio reinforcement with new Karai, SB18i and Kiva arrays

Salt Lake City’s 21,000-seat LDS Conference Centre, the main meeting hall for conferences of the Church of Jesus Christ of Latter-day Saints and summer and Christmas holiday home to the famed Mormon Tabernacle Choir, recently expanded its L-acoustics sound reinforcement system with the addition of new Karai, SB18i and Kiva arrays.

Installed by Poll Sound, L-acoustics’ local Certified Provider for install, rental and distribution channels, the new systems, which are primarily used for speech reinforcement and musical augmentation, complement an existing dV-DOSC and dV-SUB music reinforcement system provided by the same integration team six years ago.

According to Poll Sound General Manager and Lead Sound System Designer Deward Timothy, the most recent install is made up of two parts: an exploded center cluster for the front lower bowl seating and a delay ring for the rear lower bowl seats.

The front lower bowl system features three arrays of 10 Karai enclosures fanned out in an LCR arrangement blanketing coverage to the main aisle approximately 100 feet back. Low frequencies are supplied by two cardioid sub arrays each consisting of three SB18i hung between the KARAi arrays.

A delay ring consisting of seven arrays of four KIVA modules covers the rear lower bowl seats on the backside of the main aisle. With the far rear corners a considerable distance from the center cluster, two more four-element KIVA arrays were installed to extend coverage to those areas. Furthermore, two additional arrays were installed over the rostrum area to provide both front-fill and masking of any remaining rear-of-room reflection.
