Connecting Cables
To use your 4K AVR-Key:
• Connect a HDMI input cable to the HDMI input.
• Connect a HDMI output cable to the AVR/Audio output.
• Connect the AVR-Key power supply.
• Connect any additional HDMI output cable for display pass thru (optional).
As shipped, the AVR-Key defaults to 720p60 for the AVR audio stream on the output port. Make sure
that you are using 600MHz certified HDMI 4K cable if you plan to set up a 4K60 4:4:4 600MHz 18Gbps
link in your setup.
Please note that AVR-Key does not require a display to be connected at the output, you can extract Full
HDMI sound to feed your AVR, without necessarily having a display attached at AVR-Key output.

Power/Status LED
The AVR-Key logo will glow Blue when in use. When the AVR-Key first receives an HDMI signal the logo
will quickly turn on, then off, and then on permanently to indicate that the HDCP handshake has been
completed.
The status of the blue logo may be used for troubleshooting:
[Logo OFF]: Insufficient power or no incoming signals. Use the AVR-Key power supply, make
sure the source and sink devices are correctly connected and ON.
[Logo ON]: The AVR-Key is powered and receiving and decoding a HDMI signal.
