In the past Noisebridge's AV systems have been randomly put together through necessity without much thought of reliability for others to use after their installations. The projector wouldn't be pointing in the right direction, or moved elsewhere in the space, or a needed adapter and cable would be missing because someone decided to use it on another computer in another room without replacing it.
* Instructions TBD


The idea with the current system is to provide a really easy means of having a presenter or teacher come to the space and start giving a class or talk without needing to figure out how to make the AV system work, or to hunt down missing cables and other components so they could plug in. Everything that's involved in making this system work is now anchored down.
=FAQ=


===But I would like to hack on this system because something is broken or I want to make it better!===
==What do we have?==
Due to the nature of Noisebridge hacking is always allowed, however we're hoping that with how "locked down" this system is, needless hacking that'll end up in a broken system for future teachers and presenters will be discouraged.


If you feel like you want to help make the A/V setup even better or simply want to understand how it all works, there are other hackers willing to meet up with you, show you the insides of the lock boxes and potentially give you access. To contact us please send an email to the A/V mailing list.
We currently have an Epson 2150.

# Ensure the amplifier is powered on.
# Go to the mixer and make sure it is on and that the volume knobs for "Master" and your particular chosen input are higher than 0. NOT TOO HIGH THOUGH! DON'T BLOW OUT THE SPEAKERS!
# Ensure 3/4" cables run from amplifier to each speaker.
# Ensure XLR cables are running from top of mixer (output) to back of amplifier (input)


# Bring down the screen with the remote screwed to the column.
