Gefen EXT-UHDA-HBTL-RX is a 4K Ultra HD HDBaseT™ receiver with audio de-embedder and POH. This audio receiver features bi-directional power over HDBaseT™ (POH) which provides power to the receiver or a compatible sender unit over the link cable - only one side will need external power. With a small, low-profile enclosure allows this to be surface mountable and can be hidden away.
