How to use PA systems
|
||
By the Good Reverend Bill
|
||
|
||
Okay, so you're tired of those amazingly hideous announcements that school administrators
|
||
like to torture you with in the wee hours of the morning when all you want
|
||
to do is get a nap in first period? Want to get even with them for waking you up?
|
||
SIMPLE!!!
|
||
The Public Address systems used my most schools are 1) CHEAP 2) UNPROTECTED
|
||
3) FREE FOR THE TAKING!!!
|
||
It's so amazingly easy to break in to these things, all you need to know is a little about
|
||
how they work.
|
||
The systems run from speaker to speaker at a line voltage of 70 VDC, (30 VDC in Europe)
|
||
The voltage is stepped down using a line tap transformer that sits ontop of each speaker
|
||
in the line. To build yourself an access port, all you need to do is, 1) pop the speaker
|
||
out of the ceiling 2) reverse the transformer 3) toss a cheap audio amp into the
|
||
ceiling 4) add a remote access device (ie, a fischer price walkie-talkie) 5) plug
|
||
the thing into some source of power.
|
||
That's the general overview of all of it. Now for some more detailed info.
|
||
Select a hall speaker, that way no one will notice if it isn't functioning (which it won't after
|
||
you modify it). Go into the building after hours with the following: 1 cheap Radio Schlach
|
||
audio amp, try to get a PA amp if you can (steal it, card it, whatever), 1 walkman or
|
||
tape player that has a remote jack so you can operate it from down the hall by a pushbutton
|
||
(also sold at radio schlach, it's intended to be used as a remote control for the record
|
||
function of the tape player, but if you just push play, it'll serve a different purpose), an AC
|
||
cord so you can get some juice to it, and some hookup wire or something to connect
|
||
it all.
|
||
Now, unscrew the ceiling plate from the speaker and pull it down from the ceiling, take the
|
||
wires off of the speaker and then set the speaker somewhere safe (resist the urge to
|
||
steal or destroy it , you'll need it to cover your handiwork). Take the transformer from the
|
||
speaker and connect two leads from the output on your amp to the lesser input on the transformer.
|
||
Then, take the two wires that came from the ceiling and put them onto the higher output on
|
||
the transformer (the one that runs out at 70 volts). Set the switches on the amp so that it
|
||
will come on at maximum volume when juice is applied. Hook the outputs from the tape player
|
||
into the external input on the amp. Plug the remote into the remote port (duh!). Toss all this
|
||
into the ceiling and find some way to run an extention cord into the whole works to get power
|
||
(you might consider wiring it directly into the AC supply on the wall but be careful that you
|
||
aren't grounded when you do, you can work with hot wire so long as you stay insulated and
|
||
don't touch more than 1 wire at once). Run the remote down the hall and install it in to some
|
||
empty locker or something where it can't be seen (get creative, if they see your dropoff then
|
||
you're fucked). Make sure that the tape player is pushed in to play and that it has power.
|
||
Finally, put the ceiling plate and speaker back up there and make sure that everything looks
|
||
normal. You're finished. Go out and get drunk but make sure that you aren't absent the next
|
||
day.
|
||
Allright, go into school and sometime after class begins, make an excuse to go to your locker
|
||
(you have a sudden urge to piss?).
|
||
Go to your switch, hit it, and get the hell away, maybe go back to class or something.
|
||
Just get away from it to avoid any shit. The thing will stop when the tape stops playing (unless
|
||
you used a REALLY cheap tape player that doesn't have an automatic stop function.
|
||
You can modify the thing with a Fischer Price walkie-talkie so that you can make "live"
|
||
announcements (get your friends out of class, whatever). Just keep in mind that you'll need
|
||
to disguise your voice else take the wrath of the powers that be.
|
||
|
||
Thanks to The Graduate who taught me all of this (Digital Terrorist, we're gonna have
|
||
to use this stuff someday ,you know)
|
||
|
||
And keep an eye out for Channel1.txt, which will describe methods for gaining
|
||
access into that sadistic Channel One system which holds an audience captive
|
||
whilst it feeds their brains with trash and prolefeed.
|
||
|
||
ENJOY!
|
||
THE TAKING!!!
