12 giotto's? i love the sgm giotto's.. well hey.. lucky your not in india.. i believe they have lot's of DC mains! well.. gensets.... they are fun. i heard a myth of a guy who pissed on a genset earth stake and got fried.. but this tv show mythbusters did that experiment on a electric train rail and busted it. had generator dramas once at a mega laser show on a waterscreen gig (i was just a roadie :), and im not talkin crab lasers, the real 'burn a hole in you, send you blind' kinda stuff' where the laser's not supposed to stop on one spot (like on someone's eye in the audience!) the genset was a 500kVA truck-based rig, but dropped out in the middle of the gig and killed the computers, droped the water-screen and killed all the lights and PA, but the main laser was was on a seperate mains power!! the laser was pointing out into the crowd somewhere!! so someone grabbed some cardboard and blocked the beam until it was reset. the laser burnt holes thru the cardboard like a drill into concrete.. slow but it got there! gig stopped for 10 minutes while this laser guy was pulling his hair out starting all his gear back up! foh was a shipping container on the back of a truck in the middle of a speedway, huge fireworks were going off like 5 meters away from us, for about 10 minutes... monster trucks and stockcar racing... man that was a cruizy gig.. rock on in Jeddah Martin, hip Martin Searancke wrote: >Im currently on a gig in Jeddah (Saudi Arabia) and will never complain about the state of power or facilities in NZ or Australia again. >Its common here to get a Europe, UK, and US socket all in a row (but its all 240V). >We finished one gig last week and on the evening of the second to last night we had a power serge that took out about 12 SGM fixtures.
