The 7707CVRA is a VistaLINK® capable, composite analog video and analog audio fiber receiver for broadcast quality video signals. This single card module accepts a fiber optic input from the companion 7707CVTA Composite Video and Analog Audio Fiber Transmitter, demultiplexes the signals, performs D to A conversion and outputs NTSC or PAL analog video and up to four balanced analog audio signals.
The 7707CVRA-2 Dual Composite Video and Analog Audio Fiber Receiver is a dual channel version that accepts a fiber optic input from the companion 7707CVTA-2 transmitter, demultiplexes the signals, performs D to A conversion and outputs 2 NTSC or PAL analog video signals and up to four balanced analog audio signals.
The 7707CVRA and 7707CVRA-2 occupy one card slot and can be housed in the 1RU 7801FR frame which holds up to four single or two dual slot modules, the 3RU 7800FR frame which has a 15 slot capacity, the portable 3RU 350FR frame which has a 7 slot capacity, or a standalone enclosure which holds a single module.
