V-9963
DIGITAL FEEDBACK ELIMINATOR
GENERAL DESIGN
The V-9963 is designed to eliminate acoustic
feedback. When a page is made, the message is
digitized and saved. Upon completion of the live
page, the message is released for broadcast over
system speakers. (While this page is being broadcast,
another page can be recorded). This eliminates the
offensive squeal of feedback commonly produced by
telephones or microphones when making a page.
