The 7700ADA6-EQ-L is an equalizing 1x6 Analog Distribution Amplifier with passive loop thru. The 7700ADA6-EQ-L features one balanced equalized input, one passive looping output and six outputs. The module has been designed to distribute a wide range of analog video signals. It can also distribute other pulses and signals that are less than 2V p-p. The 7700ADA6-EQ-L occupies one card 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.
