Following the links to the supplier's website gives a price of $10,000 for the complete
kit or $2,700 for the chipset. Far cheaper to buy a projector and pull it apart!

I don't think I've ever seen an MSDS for a clamp before.  I see the  
main hazard is from breathing the fumes or dust from the clamp  
(fumes?  dust?), but you should also wash your hands after touching it.

Interesting product.  But "Metal fumes fever"?  I've had "Cat Scratch Fever"
and "Saturday Night Fever", but never MFF!

    Metal fumes fever is something welders get.  Usually it is from welding
something that has been zinc plated (galvanized) with insufficient ventilation.
The vaporized zinc when enough is inhaled will cause a fever.  Other
metals pose similar risks.  This is usually for production welders, who are
welding for a full day of work, five or six days a week. Using these things
with galvanized cable will likely release a superfine dust of zinc which could
pose a similar hazard.

Ductmate says that you must use Ductmate wire rope to get the
specified ratings for the Clutcher.  They do not seem to give any
specs on the diameter of their wire rope.  Ductmate's WR20, which
comes in both 7x7 and 7x19 constructions, has a BS of 1699 lbs., which
would be slightly less than the 2000 BS of a 1/8" diameter GAC.  This
leads me to believe that the Clutcher is designer for a metric sized
wire rope. Too bad, it sounds like a pretty good piece of hardware.

Having done a fair amount of galvanized welding on past projects, I can
add that it's not the superfine zinc dust that causes metal fume fever,
but vaporized zinc oxide.  It's almost like an allergic reaction to the
ZnO, in that if you are working with it for an extended length of days
your body acclimates itself to the presence of the fumes, and one
usually only suffers from the fever after the first day or two of
welding.  Symptoms are basically identical to those of the flu, with a
low-grade fever, fatigue, and general achiness being the most
predominant.  It goes away in about 24 hours, and there's been no
long-term ill effects discovered or described in any of the literature.

Hi all,

I'm looking to get a power sequencer for my audio equipment. It would turn 
speakers, amps, mixers, etc. on and off in the proper sequence.

My research has only come up with one model, by Furman, and fairly expensive 
at that. Does anyone have a particular favorite?  (Chris Babbie?)

Thanks,

This may sound like an awful daft question, but is there a particular reason
why you'd want to have an auto-sequenced power module?
I mean, I know that there IS a correct sequence to turning on audio gear,
and that some items are far more critical than others, but is this really a
justifiable expense, or a 'toy' that you can really do without?

Are you the only guy that will use the gear? If so, YOU know which order to
switch on. If not, wouldn't it be simpler/cheaper to clearly label the items
in order?

To me, I'd have thought there would be other more useful investments to
make.....

Just a thought.

We've had the Furman power ports in our system for 9 years now.  They've been working great.  It's nice to be able to just turn a key to turn the system on and off especially since my amps are located above the stage.

The drawback is that my students don't pick up the first on- last off concept as easily as if they had to do it themselves.

A fun story related to these:  One day at the end of a show my tech was speaking to a friend as the audience was leaving.  While they were talking the mixer and outboard rack shut off.  The friend asked what happened since he didn't see the tech do any thing.  Patrick explained that when we book a group we charge them by the minute and ask them how long the show will be then we set the sound system on a timer.  The guy was impressed at how close we had timed the show.

Middle atlantic products makes a system.  The installation that i have seen 
has been used over the past 2 years without major incedent, and was pretty 
easy to expand.  Not sure of the prices though.

And I am a big fan of power sequencers... especially in an educational 
setting when you dont have 100% control over who is turning the system on 
and off.

I deal with a lot of students and interns. While I try and be involved at 
the start of every show, I can't be in the theater 24/7.  (Been there, done 
that.)  And while I've posted notices on colorful paper and in large print, 
several individuals have made it clear that reading is a skill which 
surpasses their capacity.

So, yes: I'd like to get a system that makes it fairly foolproof.  Over the 
course of several years, the cost of the power sequencer is less than the 
cost of replacing speaker cones and amplifiers.  And it's nice to not hear a 
loud "pop" every time someone else sits behind the board.

If I hadn't already got a fairly decent working system (wireless and 
handheld mics galore), I'd be concentrating on building up my inventory. 
Since I'm already close to where I want to be, I can look at nice shiny toys 
for a change.

Now, when I finally have enough in the lighting budget to trade out those 
last ghastly PAR cans for a Source Four .....

Matt -  

The crux of it is this:  No one who has not been trained and tested  in 
writing (and hands-on) should be touching any of your equipment. PERIOD. This  is 
for your safety as well as theirs... and, as you have already found out, for  
the well-being of the equipment. Test need not be fancy, just needs to show 
that  the operator knows how to safely work with the equipment. Save that test as 
 proof that you did check out the operator. Powering down a sound system is 
not  difficult, it's a fundamental skill of operating the system.
 
If there is no one competent to safely operate the equipment, it should be  
locked up.
 
Add another thing and it's one more component for them to mess up. :)
