Sound engineer & technical help.
I was involved quickly on this project by Magali Vaidye and had very few equipment and time. I used two table to raise speakers on tripods above audience height. I made them as far as possible from each other following the cables i had available. I also used two amplified speakers as a mono centred subwoofer under the stage. The crossover has been made by routing the output of the little 6 channel mixer through a free input, lowering the mid and the high and sending that output through an auxiliary mix on which the two speakers were connected.
The sound quality and bandwidth was surprisingly pleasant and just loud enough for anyone to hear everything from far away in parc Lafond.
Great fun during this wonderful summer day!
