See how this modular product fits in a frame:

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.

Features

  • Passive loop thru
  • Gain Control
  • High common mode range and common mode rejection ratio (CMRR)
  • Jumper selectable AC or DC coupling
  • Cable equalizer adjustment range: 0m to 300m of 8281 or 1694AA
  • Consistent input impedance if card power is lost
  • Module Status/Local Fault
