The high-performance and long-reach

Kramer WP-789T (KRA-WP-789T-W) HDMI to HDBaseT wall-plate transmitter is for video signals up to 4K@60Hz (4:2:0). The wall plate converts an HDMI signal to twisted pair, HDBaseT signal and transmits it to a compatible receiver. This wall-plate gains power via PoE (or optional 12V power supply) and extends the signals to up to 40m (130ft) at 4K@60Hz - longer for lower HD resolutions. An LED status indicator makes the unit easy maintain and troubleshoot.


  • HDBaseT 1.0 transmitter
  • Powered by PoE or optional supplied power adaptor
  • Up to 230ft at 1080p, 130ft at 4K@60 (4:2:0)
  • Pass–through algorithm ensures Plug and Play operation for HDMI source and display systems
  • Up to 32 channels of digital stereo uncompressed signals for supporting studio–grade surround sound
