Digital Feedback Eliminator

Digital Feedback Eliminator/Message Stacker
General Design
The V-9964 is designed to eliminate acoustic feedback and act as a message stacker. When a page is made, the message is digitized and saved. Upon completion of the live page, the message is released for broadcast over the speakers. While a message is being broadcast, additional messages may be recorded with a maximum of 4 messages queued per V-9964. Additionally, up to four V-9964 units may be chained together to allow up to sixteen messages to be simultaneously processed.
