Valcom Digital Feedback Eliminator/Message Stacker

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.
