LK-HBT3 is a revolutionary 4K@60 4:4:4 HDR HDBaseT Extender using the latest gen3 chipset. It can stream uncompressed HDMI2.0 signal on 18Gbps bandwidth. Deliver a crystal lossless 4K HDR signal transmission without any artifacts and latency.

Instead of using traditional TX/RX extender design, SPROLINK has combined TX and RX on a single hardware. You can use your finger to decide whether it is TX or RX in a specific application.
LK-HBT3 extends uncompressed 4K HDR signal up to 70m(230ft) using CAT6a/7 cable. 1080P signal may be extended up to 100m(328ft). In addition to HDMI 2.0 video and audio signals, LK-HBT3 carries bi-directional IR and KVM for controlling remotely located equipment.

All the advanced function design and remote power capability make LK-HBT3 an ideal solution for long-distance signal distribution of any 4K HDR professional AV display.
