The RS-121 is a 19" 1RU rack mount chassis for a single ARD-1006 transmitter, receiver, AMP-1006 video splitter module or MicroBox computer module. The nine swappable modules provide numerous configurations and functionalities to meet ever changing requirements of ProAV events. The nine swappable modules include HDBaseT 2.0 transmitter, receiver, AV over IP transmitter and receiver with Copper or Fiber interface, computer module and video splitter modules. The RS-121 can also be wall mounted using a wall mount bracket. This provides a significant maintenance advantage and configuration flexibility. In case of a failure, the transmitter, receiver, splitter or computer module can easily be swapped out in seconds.
