Anyone who has ever used technology knows one thing: IT FAILS. A LOT. This is more true in the realm of professional audio than in any computer or circuit I have ever worked with. In this instructable, I hope to teach you some concepts that will help you run audio with as little problems as possible. Please note that this instructable only covers VERY BASIC problems you can run into with a sound system. If there is any problem that you would like me to cover, please leave me a comment or contact me.
You can also see my other instructables on sound:
How Sound Works
The Concept Of Sound Pressure (SPL)
Before we go into how to fix problems there are a few things that I strongly believe about sound that you should know.
1. You can't program sound.
2. If it can fail, it will. If there is no way possible for it to fail... then it sill might.
3. You should know your equipment better than the back of your hand before attempting to troubleshoot.
With that in mind, let's talk audio!

Feedback is a howling noise. It can either be on the high end (very high pitched) or low end (very low pitched). Feedback is caused when a mic is too loud and is able to "hear itself" in the speaker. This starts what is called a feedback loop. Tiny imperfections in the mic are amplified, and looped over and over again, causing the howling effect.
You can fix feedback by turning the volume on the mic down (the fader on the sound board), turning the gain down (usually the knob at the top), moving the mic behind the speakers, or turning the main fader(s) down. The preferred way to fix it is to turn the gain down, or the main fader(s). (The main faders affect your gain structure.) If you don't know what mic the feedback is coming from, you should use the main fader(s). To prevent feedback keep your volume and/or gain as low as possible.
