=== Feedback === | |||
[[Feedback/Microphone|Feedback]] happens when the sound from the loudspeaker enters the microphone or instrument with pickup only to be re-amplified.

=== Bass Regeneration === | |||
[[Bass Regeneration]] is a special class of feedback, or regeneration, that exists in all live amplification systems. It is a very insidious and hard-to-confront phenomenon, but it is responsible for a lot of bad sound. Resonances of all kind, including those of musical instruments and those of large “boomy” rooms will also contribute to bass regeneration. ...

If placed in a corner, ask if you can be placed in the center or a wall. If you the "short" wall in a rectangular room is wide enough, then that is probably your best choice for the wall behind you (if the long wall is not greater than 100 feet). | If placed in a corner, ask if you can be placed in the center or a wall.
