The Gefen GF-EXT-HDe-HBT3 HDMI eARC Extender over HDBaseT 3.0 is designed to deliver exceptional audio and video performance over long distances, making it ideal for high-end home theaters, conference rooms, and broadcast environments. Powered by advanced HDBaseT 3.0 technology, this extender transmits 4K Ultra HD content at 60Hz with 4:4:4 chroma subsampling and 8-bit color depth up to 328 feet (100 meters) over a single CAT6a cable. Its robust design ensures that every detail, color nuance, and audio track is preserved from source to display, supporting HDR10, HDR10+, Dolby Vision, and HLG for stunning visual clarity. The system's support for eARC, ARC, optical audio, and PCM 2-channel de-embedding allows for studio-quality sound, including Dolby Atmos, Dolby TrueHD, DTS:X, and DTS-HD Master Audio, providing a comprehensive audio experience alongside high-resolution video. The built-in HDMI loop-out with a 4K-to-1080p downscaler enables local monitoring at a lower resolution, which is particularly useful during setup or troubleshooting. An integrated pattern generator and HDCP toggle facilitate quick diagnostics without the need for external equipment, streamlining installation and maintenance. Additionally, the system supports bi-directional PoC (Power over Cable), reducing cabling complexity by requiring only one power supply to power both units. Control options include IR pass-through and RS-232, ensuring seamless integration with existing control systems. Constructed with a durable metal enclosure and designed for surface-mount installation, the GF-EXT-HDe-HBT3 combines professional-grade reliability with flexible mounting options. Its low power consumption and comprehensive feature set make it suitable for demanding commercial and residential applications where precision and dependability are critical.
