# what do you do when the mains are blown?

I work at a semi-professional theatre. That being said, what do you do when a 'semi-professional' volunteer blows your mains?

I'm not sure how easy it would be to get the cluster to the ground. It is dead hung and concealed by a metal frame covered by fabric. If we take out the center seats in the second row, we may be able to get to the front. This theatre doesn't have alot of down time, so the less amount of time we spend on this project, the better. From the apron of the stage we can get to the back of the cluster on the lift. From what I did see, there is a loaded cab, but I'm not sure if there is a horn in there. Also, beside the cab there are two horns about 2' long and I guess about 20" wide at the front of the bell. Those should be easy to get to. I'm not sure if lowering the cluster will be an option. We would need to have the pro's come in and do it and I doubt they could get it done as soon as we need it. Hopefully the only horns are the ones that are easy to get to.

Well if the horns are easy(ish) to get to I would start there. But whilst you are there just see if you can take a better look at the cab. However, givine that you have two horns in the cluster I would assume that the cab is loaded with drivers only.

Hmmmm.....

I would have this "Semiprofessional volunteer" pick up the bill for your repairs and be made responsible for getting them fixed immediately, or you will file a police report to have him arrested and charged for vandalism, and have the theater SUE him in civil court for damages & repairs, legal fee's and down-time costs of lost revenue the theater suffers, because of his blatent ignorance, negligence and abuse of equipment that is not his own..

Thats what I would do...

That said--sounds like you are stuck with either getting to the horns yourself or hiring someone to do it. From your description of the horns and where they are, they are probably JBL, Altec or Community...either way once you get to them (probably by scaffold or genie-lift with a raised balancer scaffold that goes over seating areas) that is not the hard part--opening them up IS usually the hard part. Most of those long and wide horns are well sealed and use recessed ALLEN screws and sealent in the magnet around the diaphram--in other words its not work you can do easily in the air.

Also keep in mind--If you un-do the rigging to get them down--you are then voiding any warrenty and liability from the original company, and opening yourself up to a liability issues should they fall or have issues later on. Replacing a diaphram in a horn is simple...but getting to them and opeining them up in the air is not. I would suggest you get the original contractor who put the system in to do the repair...or at the very least supply you with the equipment list and drawings of the installation--it may shed some clues on how to proceed and the exact gear or parts you will need to get replaced...plus the theater may have a contract or service warrenty that may still be in effect with this company you may not know about.

Doing the work yourself or with a friend--well that may be risky in liabilities, costs, damages and insurance coverages--should someone fall or be hurt while doing this repair work..or later on if the rigging you un-do should fail....

just a few thoughts.. Good luck...

The horns looked fairly lightweight. I believe they were mostly fiberglass and hung by brackets. So maybe just the horns alone wouldn't be too hard to get out. I wouldn't want to touch the cab, but as Mayhem pointed out, it is probably loaded with drivers only. I'll see if I can get to it sometime tomorrow and determine the caliber of rigging/take-down we will have to do. If it is too heavy, we will have it professionally done. As for the guy who did the damage, I just found out that he was a paid musical director for the current show. So he didn't even belong in the booth, but it was the first day of Tech and the staff was worried that the real sound guy wouldn't show up. I'm not sure if the MD has been told yet, but I'll run it by the Exec's and see what they have to say.
