Bridges the gap between modern eARC-enabled displays and distributed AV systems by extending uncompressed 4K60 4:4:4 video, multi-format audio, USB 2.0, and Gigabit Ethernet up to 328 ft over a single CAT6A cable. The EXT-HDBT3ARC-TX transmitter leverages HDBaseT 3.0 to deliver 18 Gbps of uncompressed bandwidth alongside full eARC/ARC audio return, bi-directional IR and RS-232 control, and configurable USB Host/Device mode — all through one network cable run.

Video passes through at full 4K@60Hz 4:4:4 with HDR10, HDR10+, Dolby Vision, and HLG intact, while the eARC path returns lossless Dolby TrueHD and DTS-HD Master Audio from the display back to the transmitter’s HDMI, analog L/R, or SPDIF output. Bi-directional 24 V POC eliminates the need for a second power supply at the remote end, and the built-in Gigabit Ethernet port lets integrators consolidate AV transport and network infrastructure on a single cable.

  • HDMI 2.0b and HDCP 2.2 compliant with HDBaseT 3.0 standard for uncompressed signal transmission
  • Uncompressed 4K@60Hz 4:4:4 video with up to 18Gbps video bandwidth over a single CAT6A/7 cable
  • HDR pass-through including HDR, HDR10, HDR10+, Dolby Vision, and HLG formats
  • Full audio format support: LPCM, Dolby Digital/Plus/EX, Dolby TrueHD, DTS, DTS-EX, DTS-96/24, DTS High Res, DTS-HD Master Audio, and DSD pass-through
  • Transmission distance up to 100 meters (328 feet) via a single CAT 6A/7 cable
  • eARC/ARC audio return channel support — audio returns to the HDMI IN port, HDMI OUT (Audio Only) port, and SPDIF OUT port of the transmitter
  • SPDIF audio reverse transmission for legacy audio equipment integration
  • Bi-directional IR, RS-232, and Gigabit Ethernet (1000Mbps) signal pass-through for full system control
  • USB 2.0 transmission with configurable Host/Device mode for KVM or peripheral extension
  • Bi-directional 24V POC (Power over Cable) — either transmitter or receiver powers the other unit, eliminating the need for dual power supplies
  • Transmitter supports audio embedding and de-embedding via L/R analog port with front-panel switch selection
  • HDMI loopout or Audio Only output mode selectable via front-panel switch on the transmitter
