KanexPro 18Gbps 4K HDMI Audio Extractor with Dolby Atmos

Experience cinema-quality audio-without-compromise in your living room or professional setup. The KanexPro HAECOAX3 is a next-generation HDMI audio extractor engineered for demanding home theaters and conference rooms. Boasting 18 Gbps bandwidth and full HDMI 2.0 compatibility, it preserves 4K/60 video while de-embedding the HDMI audio stream to versatile outputs. Whether you’re connecting to a high-end Dolby Atmos-enabled AVR, a soundbar, a digital DAC, or traditional speakers, this device delivers pristine sound alongside crystal-clear picture. Designed for simplicity and performance, it helps you consolidate your gear, reduce cable clutter, and enjoy immersive audio without sacrificing video quality.

• 80/18 Gbps bandwidth with HDMI 2.0 compatibility: The extractor is built to handle the latest HDMI 2.0 specifications, ensuring smooth 4K at 60 Hz with wide color depth while maintaining a robust signal for audio de-embedding. This ensures your video remains sharp and free of artifacts even as your audio channels are extracted for separate processing in your AV chain.
• Professional-grade audio de-embedding: De-embed HDMI audio streams from any HDMI source and route them to multiple digital and analog outputs. This means you can feed a modern AV receiver or soundbar with Dolby Atmos-capable audio while your display continues to receive pure video. It’s ideal for homes with legacy audio systems or high-end digital interfaces.
• Dolby Atmos compatibility for immersive sound: The KanexPro HAECOAX3 supports Dolby Atmos pass-through on the extracted path, enabling your compatible receiver or soundbar to decode object-based audio for a truly immersive soundtrack. Pair it with a capable Atmos setup to maximize home theater impact without changing your video wiring.
• Flexible multi-output audio options: Output audio in digital format via Optical (Toslink) and Coaxial (S/PDIF), plus analog stereo via a 3.5 mm or other dedicated line-out depending on model configuration. This gives you flexibility to connect to modern DACs, legacy amplifiers, or compact sound systems with ease.
• Preserved video while extracting audio: The extractor maintains 4K/60 video resolutions and supports the essential video features you rely on, including HDR and high-bandwidth content, so your picture quality stays crisp while audio is routed to your preferred speaker system. This keeps your home theater experience cohesive and compelling without compromise.

How to Install KanexPro HAECOAX3

• Step 1 – Connect the source: Plug your HDMI source (Blu-ray player, game console, streaming device) into the HDMI input of the KanexPro HAECOAX3 using a high-quality HDMI cable.
• Step 2 – Connect the display: Run another HDMI cable from the HAECOAX3’s HDMI output to your television or projector to preserve video quality for on-screen content.
• Step 3 – Attach audio outputs: Connect the digital audio outputs (Toslink optical and/or coaxial SPDIF) to your AV receiver, DAC, or sound system. If you require analog audio, connect the 3.5 mm stereo output to your analog amplifier or speaker system as needed.
• Step 4 – Power up and configure: Connect the power supply to the KanexPro unit and switch it on. If your source or display supports HDR, ensure they are configured to deliver proper color and metadata; the extractor will preserve these signals as it passes video through to the display.
• Step 5 – Test and optimize: Play a 4K60 HDR/Atmos-enabled title or a test disc to verify that video appears correctly on the display while audio streams route to the chosen speakers. If you encounter audio delays or lip-sync issues, adjust your EDID settings or try a different output combination to achieve the best sync with your system.
