# Technical Disaster Inspires Strict Letter

Tonight was amazing fun. Our drama club decided to put on a club-like Comedy Night in our new senior caf. Everything panned out pretty good, with a few minor difficulties. The percussion ensemble was pissed at us because they thought they would be able to have food for their event in the same caf as we were performing in, the woman, however was not aware that there was a difference between the 2 cafs and had signed up for the old one on the master schedule. So they got screwed, but luckily they were out of there before the performance because we needed a "backstage". (The two cafs are connected, out "stage" on the wall adjacent to the old caf.

I am the master lighting tech for our school as of current, so I rigged up a couple pars on trees in the caf, ran them to a dimmer pack and from that straight to the board we took down from the booth. I hooked up everything and everything was golden. So, being that I was performing in the show, I scurried off to get ready for our skit. As our skit starts, there are no lights except the evening light from the skylights. So I knew something had gone wrong and the person I set in charge of the board was unable to fix it. Then, in the middle, the caf lights come up. The switches are in a locked snack shack accessible only from the main hall by a master key. So after my scene, I went to figure out what went up. I find that the dimmer pack overheated and the circuit was cut. After letting the whole thing cool, we were able to reset everything and get the lights back up. So we go an turn out the caf lights. And 5 minutes later, the pack blows again. And after a few minutes, again. So we gave up and finished the show with the lights up. Boo to that.

sounds to me like you're just using the wrong dimmer packs. they may not necessarily be crappy - just not intended for heavy use. 'DJ' dimmer packs usually cannot handle a constant theatrical lighting load.

as far as it being hot, that doesnt sound right at all. you would think it should keep blowing fuses if there is a short or overloading situation.

If the extension cords powering the dimmer are hot then you are pulling too puch power from the dimmers. Make sure to check to see what the max power you can pull per pack. My school borrowed some that allowed only 2400w per pack and 400w per channel. On the other hand our installed NSI Dimmers can handle 2400w per channel.

I beg to differ, we use American DJ dimmers in our theatre and they work without fail.

We have to do a lot of our tech under the table,
Sadly, that's the same here. Originally after the BOE cut the AV position, which controlled the auditorium, the principal said I couldn't be on the catwalk. This is after 30 years of students doing everything on the catwalk. He wanted me to direct maintenance people from the ground, telling them how to focus, aim, etc. So thankfully the musical director told him that was not possible and now I'm allowed to go up there. Honestly, if I had to direct the maintenance crew to aim lights, I'd probably have quit. lol

sorry - thats me

you must be using one of the few models that supports that heavy of a load.
