If upgraded HDMI 2.0 video equipment makes your older audio equipment incompatible, the HDfury AVR Key HDMI Audio De-Embedder can make the difference. Using its most essential function, the AVR Key de-embeds the HDMI audio stream and outputs it along with a blanked 720p or 1080p video signal over one HDMI output, and loops the original source input through to the other HDMI output. Send the looped signal to your new display, and connect the AVR output to your older receiever. Advanced EDID management for both HDMI outputs is available to ensure compatibility with most A/V setups. A free Windows PC GUI is available for on-screen advanced controls, but most functionality can be adjusted on the device itself.
