V-9964
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,
a second message may be recorded.
Additionally, up to four V-9964 units may be
chained together to allow up to eight messages
to be simultaneously processed.
