Audio and Infrastructure Upgrade
Project Overview
Grace Church partnered with ProVision Production Design to modernize the audio and production infrastructure in its Long Beach auditorium. The project included the design, installation, programming, tuning, and commissioning of an integrated system encompassing sound reinforcement, mixing, wireless microphones, personal monitoring, system control, networking, power management, acoustic treatment, and lighting control.
Unique Challenges
Built in the 1960s, the auditorium features a 35-foot plaster-and-lath ceiling which was a challenge and took time to get the rigging points exact before creating access holes to reach the structural beams.
The entire loudspeaker system—including the low-frequency system—was flown from the ceiling. Four L-Acoustics KS21 subwoofers were deployed in an end-fire cardioid array for consistent, steerable low-frequency coverage with reduced energy behind the array. Flown A15i main arrays and A10i cross-fill arrays provided balanced SPL, consistent tonal response, and stereo imaging throughout the seating area.
