First thing- look at the power switches/ supply make sure not bimped off some how, if so
turn back on.

Secondly- check main switch board/ explain what is happening to crowd

Thirdly- fulses etc use back up gear if avail, if not bassicaly ya stuffed 

thanks for that bit of info chris,r u a london based dj? 

plus if you still dont know what to do - LEAR from someone that does

if you are a veteran in the industry you would have already made a list on what to check
to repair as well

just make sure you are always a boy scout  "BE PREPARED"

have a nice day 

Try search tough googel mobile web at search opp's try phone format should find a site
with a app's

I must be Drunk, but did anyone know what this guy is talking about ??? 

djdennis, i'm not entirely sure that HE knows what he was on about!
another point of note that i would make though. if you find the "fault" (be it a bumped
switch, temp power failure or whatever), make sure you turn your gear OFF before
rectifying the fault. if everything is left switched on, and you plug that cord that's
come out at the wall back in, you could quite easily blow stuff (in particular,
speakers). i'd suggest that if your stuff goes down, that you turn off your gear
(particularly your amps, but also your console, tables, cd's and other things that go
bump and boom), find and rectify the problem, then turn stuff back on the requisite order
as if you are starting afresh. pain in the arse i know, but that's what i'd be doing with
my own gear. coming from the owner of a few blown speaker cones!

thanks for the additional notes for others
but...
So how long have you been djing for
??
 
I been in this for over 30+ years so that is why I posted this article
in the first place
no one else was doing
it....
 
remember just because you think you know everything
its like the murphy's Law
 
Murphy must never
have imagined that his casual statement would someday become law! Murphy's Laws symbolize
the error-prone nature of people and processes. Given below is a top 10 list of Murphy's
Laws. These weren't actually uttered by Murphy. They just belong to the category of
quotations that are known as "Murphy's Laws."
 
1. Murphy's Law:
If something can go wrong, it will.
 
 
2. Murphy's
Law:
If anything
simply cannot go wrong, it will anyway.
 
 
3. Murphy's Law:
Left to themselves, things tend to go from bad to
worse.
 
 
4.
Murphy's Law:
Matter will be damaged in direct proportion to its value.
 
 
5. Murphy's
Law:
The chance
of the bread falling with the buttered side down is directly proportional to the cost of
the carpet.
 
 
6. Murphy's Law:
The buddy system is essential to your survival; it gives
the enemy somebody else to shoot at.
 
 
7. Murphy's Law:
Technology is dominated by those who manage what they
do not understand.
 
 
8. Murphy's Law:
The opulence of the front office decor varies inversely
with the fundamental solvency of the firm.
 
 
9. Murphy's
Law:
Tell a man
there are 300 billion stars in the universe and he'll believe you. Tell him a bench has
wet paint on it and he'll have to touch to be sure.
 
 
10. Murphy's
Law:
The first
myth of management is that it exists.
