HDbitT HDMI Over Powerline Extender (3 Zone)

The Lenkeng LKV380Pro uses HDbitT technology to distribute a single 1080p HDMI source to multiple displays over existing mains wiring, removing the need for dedicated AV cabling runs. This 3-zone kit pairs one transmitter with three receivers, making it suitable for homes, offices, or commercial premises where running HDMI cable between rooms is impractical or costly.

How It Works

The transmitter connects to the HDMI source and a mains socket. Each receiver plugs into a mains socket in a different room and feeds HDMI to its local display. The HDbitT protocol carries the video signal over the building's electrical wiring at up to 300 metres, provided all units share the same electrical circuit. The system supports up to four receivers on a single transmitter, so an additional receiver can be added later without replacing the transmitter.

Connectivity & Control

The transmitter includes an HDMI loop-out, allowing a local display to be connected at the source location alongside the remote receivers. The system provides 360° IR pass-back on each receiver, operating between 20 and 60 kHz, so a remote control pointed at any receiver will relay commands back to the source device. AES encryption secures the signal across the powerline link.

Setup

The LKV380Pro uses automatic scan-and-pair operation — plug in the transmitter and receivers, and they find each other without manual configuration. The system is compatible with 100–240V AC mains supplies.
