A 6.0 magnitude earthquake struck Little Antelope Valley, California on the afternoon of July 8, 2021. The tremors reached Sacramento, where Polar Focus rigging is suspending Martin Audio Ltd. line arrays at a House of Worship installation. We received the following email from our client, Keith Wackford, at Sacramento Production Services Inc.
From the Church Sound Engineer:
“I’m happy to report that the Polar Focus and Martin Audio WPS line array rigging did its job during that earthquake that just happened. I looked out and they were swinging away. What a trip.”
Polar Focus supplied a custom rigging system for this venue featuring Spine Frame Adapters, PY-UJ-Post components, as well as PE Stamped Drawings for the State of California. The rigging attachment to the roof structure was rigid, conforming to local building codes. The integral universal joints in the rigging system allowed the line arrays to gently and safely sway back and forth to accommodate the seismic event. Unfortunately, the sanctuary didn’t have video, as we would have liked to see that! Shown here are some still images from the venue.
