The 7700ADA7-EQ Equalizing Analog Distribution Amplifier is a general purpose amplifier for distributing analog signals. The 7700ADA7-EQ features one balanced input with seven outputs. The 7700ADA7-EQ has been designed to distribute a wide range of analog video signals. It can also distribute other pulses and signals that do not exceed 2V p-p. The 7700ADA7-EQ occupies 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.
