What is Feedback?
Feedback is the screeching/squealing/hooting sound heard when there is an accidental loop in the PA system. That is when the sound from a microphone is amplified and fed to the speakers and then picked up again by the microphone, this sound then carries on round and round resulting in the nasty noise. The feedback frequency depends on a number of factors such as: the resonant frequency of the room, distance of microphone and speakers, frequency response of the microphone, characteristics of musical instruments. To reduce or eliminate feedback this loop needs to be broken, here are a few ways of doing that. |

 If you'd like to know about Scan Converters (or Down Converters) then take a look at our scan converter page. This talks about converting a computer signal in to composite video and how it can be mixed with other composite signals

  Many times you want to mix a computer signal (eg a presentation or song words) with a set of video cameras and/or dvd players.
Video cameras etc, generally use Composite video (the little phono connector) and a computer will use higher resolution RGB or even DVI signals and connectors.
How can these be mixxed together, and how about overlaying the text from a computer over the top of the video cameras?
