PureLink 4K 18Gbps HDMI eARC Audio Converter

PureTools PT-C-HDEARC-4K: State-of-the-Art eARC Audio Upgrade for Your Existing AV Receiver

Get your home entertainment system ready for the next generation: The PureTools PT-C-HDEARC-4K is the professional solution to enjoy high-resolution audio formats such as Dolby Atmos and DTS:X even on older AV receivers without eARC support. As a powerful HDMI eARC adapter / extractor, it decouples the audio signal losslessly and forwards it to your sound system with a special 720p black screen, while the 4K video signal remains untouched. 

Product Highlights and Features:

• Future-Proof Audio De-Embedding: Extracts eARC or ARC signals directly from the TV and makes state-of-the-art multi-channel audio formats usable for older amplifiers or soundbars without the need for an expensive new purchase of audio hardware.
• Innovative HDMI Audio Output with 720p Signal: Transmits uncompressed audio together with a black video image, which guarantees permanent stability and compatibility with conventional AVR inputs.
• Lossless 4K UltraHD Performance: Supports full 18Gbps bandwidth for resolutions up to 4K@60Hz including HDR10, HDR10+ and Dolby Vision, so that you do not have to make compromises on picture brilliance.
• Intelligent Signal Management: Integrated reclocking and signal equalizing optimally prepare incoming data, ensuring a stable transmission even over longer cable lengths without loss of quality.
• Flexible EDID & eARC Handling: With the help of DIP switches, the communication between the devices (handshake) can be precisely controlled, which minimizes installation errors and enables a smooth plug-and-play function.
• Full Support for Modern Formats: Compatible with Dolby Atmos, DTS:X, Dolby True-HD and other high-res formats to create an immersive cinema-quality sound experience.
• Seamless System Integration: Thanks to pass-through for CEC signals, the ease of use is maintained, as connected devices can continue to communicate via a common remote control.

Conclusion

The PureTools PT-C-HDEARC-4K is the perfect link for users who want to keep their high-quality, older AV receiver but do not want to do without modern standards such as Dolby Atmos or 4K HDR streaming. It offers stable, professional signal processing that is particularly convincing in demanding setups.

Important Note: Please note that this adapter requires a dedicated HDMI input on the audio device. It is therefore not compatible with soundbars that only have an eARC port (e.g., Sonos Arc/Beam or Bose Smart Soundbar).
