Let your 4K HDMI video travel up to 328' over HDBaseT with this KD-X444L 4K/18G HDMI over HDBaseT PoH Extender Kit from Key Digital. The KD-X444L is an HDMI transmitter and receiver pair featuring a low-profile, compact design. It enables you to extend 18 Gb/s video up to 12-bit 4:4:4 UHD/4Kp30 and 8-bit 4:4:4 UHD/4Kp60 up to 328' away from your source.

The KD-X444L features hot plug detection, HDCP 2.2 authentication, CEC pass-through, TMDS re-clocking with signal regeneration, and 15 selectable EDID handshakes. IR pass-through is supported using the included Rx and Tx IR cables that send remote IR signaling back and forth between your remote control and the equipment attached to the receiver.

The kit also supports the HDR10 color profile, and audio profiles include lossless, compressed Dolby TrueHD, Digital Plus, DTS-HD Master Audio, and Atmos. Viewing the unit's status and various control functions is performed using the 3-pin Euroblock RS-232 input. There are also LEDs on the front of each unit to indicate link and power activity. Only one of the units needs to be externally powered using the included power supply since the units support PoH (Power over HDBaseT). Also included are Euroblock connectors and four brackets for mounting the transmitter and receiver units.
