My DL is fitted in a custom case with my router mounted underneath and PSU permanently plugged in. It has a loop in the cable for strain relief and the whole package is snug and safe.
I lifted the desk up a little last gig to ease the iPad out (the edge of the flightcase fouls it a little). The power cycled and a got a (thankfully) small thump through the PA. It was during the soundcheck so after closing everything down I took a look at the power connectors. The fault lay within the desk, the split centre pin of the power connector was tightly closed, causing too much play. A quick poke with a fine screwdriver opened the centre pin up a bit and it was sorted. The plug had been connected/disconnected five times at most. Just wondering if anyone else has had the same problem?
