What is audio Feedback
A deafening squeal coming from the speakers at a concert or other event that causes everyone in the audience to plug their fingers in their ears and shout, “Make it stop!”
Acoustic feedback occurs when the amplified sound from any loudspeaker re-enters the sound system through any open microphone and is amplified again and again and again.
If you speak one word at the microphone at a level of 80 dB and the loudspeaker returns that word to the microphone at 80 dB, then you can go home. The sound system will repeat the sound all day, “chasing its tail” from microphone to loudspeaker.
Feedback Eliminator
Feedback Eliminator is designed to eliminate acoustic feedback and act as a message stacker. When a voice page is made, the message is digitized and saved. Upon completion of the live page, the message is released for broadcast over the speakers.
