Extends uncompressed 4K@60Hz 4:4:4 HDMI, eARC/ARC audio return, USB 2.0, and control signals up to 328 feet over a single CAT6A/7 cable. The KanexPro EXT-HDBT3ARC-100M is an HDBaseT 3.0 extender kit (transmitter + receiver) that delivers full 18Gbps video bandwidth with eARC/ARC audio routing, bi-directional IR, RS-232, Gigabit Ethernet, and configurable USB 2.0 — eliminating the need for multiple cable runs in long-distance AV installations.
Compliant with HDMI 2.0b and HDCP 2.2, the extender supports HDR10, HDR10+, Dolby Vision, and HLG pass-through alongside Dolby TrueHD, DTS-HD Master Audio, and DSD audio formats. Six eARC/ARC/SPDIF switching scenes provide flexible audio return routing to amplifiers and soundbars. The transmitter supports audio embedding and de-embedding via 3.5mm analog I/O. Bi-directional 24V POC allows a single power supply to power both units.
