[QUOTE="Tim McCulloch, post: 34512, member: 67"] Re: Psychoacoustics A few years ago we had a Nexo Geo8 rig on demo. Conveniently coincided with a university fine arts series presentation of Ladysmith Blak Mambazo. We flew the rig from lifts, pretty much right behind the fire curtain line. The group was upstage about 5'. Their engineer asked me to add 3ms of delay, then increment a few 0.10ms until he was happy. Up in the top seats it didn't matter as much, but in the first 1/4 of the hall it had a solid stage image that didn't sound like PA. It was a proper alignment of the PA with the acoustic source for most of the seats where you got appreciable coverage from the singers on stage. He put spike marks on the floor and stand base... In other circumstances and venues this might have not been an issue, but that day in that room it was the right thing for the audience. Frankly I thought it was stunning; it had an intimacy as if the group was singing just a few feet from you and directly to you, a very personal experience. What a great day at work. :D Have fun, good luck. Tim Mc [/QUOTE]
