Cure Autism Now, in conjuction with the Chaka Khan Foundation, is touring the US to bring awareness to the issue of autism. This particular event was the "Walk for Autism" - a fundraiser walk accompanied by musical performances. Chaka Khan performed a song live for the audience, followed by a live set from The Voltaires. Naturally, PCA Audio provided sound for the massive outdoor event, making use of our new PAS line array system to address 4500 people. A configuration of 6 line array boxes per side along with 3 subs per side were used to fill the main parking lot of the Palisades Center Mall in West Nyack, NY with crisp, clear sound.
