The HDfury team would like to thank you personally for purchasing the 4K AVR-Key!
HDfury AVR-Key is a 4K60 4:4:4 600MHz 18Gbps HDMI2.0b Level A Full HDMI Audio extractor device
built for system integrators and advanced users that will please everyone else as well.
By supporting the max bandwidth and data transfer rate of the HDMI2.0b standard and by extracting
and offering full HDMI audio via a self-generated 720p60 or 1080p60 blanked stream, AVR-Key is set to
support and integrate any AVR from any HDMI revision into any HDMI setup including DV/HLG/HDR10+.

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.

Selecting your Windows PC Driver for USB GUI and Firmware update
Make sure to install the right Silabs driver for Windows PC based on your Windows OS version and USB
port version.
Silabs Driver 4.0.0 for XP/VISTA/WIN7/WIN8/WIN10
Silabs Driver 4.0.0 - ZIP - 9.18 Mo
USB2.0: WIN XP / VISTA / WIN7 / WIN8 / WIN10
USB3.0: WIN10 / Partial support for others Windows version.
Silabs Driver 3.9.2 for XP/VISTA/WIN7/WIN8
Silabs Driver 3.9.2 - ZIP - 1.65 Mo
USB2.0: WIN XP / VISTA / WIN7 / WIN8
USB3.0: WIN XP / VISTA / WIN7 / WIN8
If you are using Windows 10, the Silabs Driver 4.0.0 is mandatory.
However, Silabs driver 4.0.0 only have partial support for USB3.0 on Win8 and previous Windows
version, so you might prefer the 3.9.2 in such case.
For installation simply download from the above link, unzip and then run the .EXE file
Silabs 3.9.2 driver: run the USBXpressInstaller.exe
Silabs 4.0.0 driver: USBXpressInstaller_x86. exe for 32bit or USBXpressInstaller_x64.exe for 64bit.
Once you have correctly selected, downloaded and installed the right driver, you can proceed with
either updating Firmware (p.14) or using GUI utility (p.16)
Both Firmware update and GUI utility provides 2 directories labelled as per Driver version, make sure to
use the right directory matching your driver version.
Ex: If you installed 3.9.2 driver, Use the 3.9.2 directory to run Firmware update or the 3.9.2 directory to
run the GUI utility.
Note: You can install or remove any driver any time:
Control Panel > Program > Remove Software.

FAQ
My display is supposed to accept 4K60 4:4:4 signals but it does not work?
For most UHD TV set we tried, there are always extra configuration options to active in order to achieve
a 4K60 4:4:4 600MHz link. For ex, on samsung: in order to enable the 444 colorspace for 4k in Samsung
TV’s you must go to "settings" and "hdmi" and "UHD color" and enable it. Then also you must assign the
HDMI port1 as "PC" in the tools menu. Only after these two steps will 600MHz be accepted. Similar
activation tricks are required on most UHD TV’s. Additionally, most UHD TV’s only have specific ports
that are 600MHz capable.
I have a PC mode on my TV (or a PC monitor) what resolutions are supported for graphics mode?
All PC graphics mode within the 600MHz bandwidth are supported, including ultra-high resolution such
as WQSXGA, QUXGA, QFHD, WQUXGA, 4K.
What output resolution does the AVR-Key support in HDTV mode?
All known SD, HD, Full HD and UHD formats are supported including: 480i50,480i60, 480p50, 480p60,
576p50, 576p60, 720p50, 720p60, 720p100, 720p120, 1080i25, 1080i30, 1080p24, 1080p25, 1080p30,
1080p48, 1080p50, 1080p60, 1080p72, 1080p75, 1080p96, 1440p50, 1440p60, 2160p24, 2160p25,
2160p30, 2160p50, 2160p60, 4K DCI (these are examples only, anything within the 600MHz bandwidth
is supported.)
What version of HDMI does the AVR-Key work with? Do I need HDMI 1.3/1.4a/2.0a? Does it matter?
It does not matter. HDfury AVR-Key works with any version of HDMI from 1.0 and up to latest.
Do I need to set anything special in my HDMI source device to set the resolution correctly?
No. The HDfury AVR-Key will be detected as 2160p60 4:4:4 capable device by your source and it will
always accept and process the highest quality stream from your source devices. There is no need to set
the HDMI source to any specific resolution.
Is there any latency (delay) introduced to the signal?
Virtually none. The latency added is in the order of a few pixel clocks only. Nothing noticeable at all.
What is the USB port for?
To provide power from the supplied USB power unit and for firmware upgrades when new (additional)
functions and enhancements are offered.
What about long HDMI cable runs? Can I expect issues?
For 600MHz users must use "high speed" cables, or 600MHz/18Gbps certified. For 4K30, 1080p or less
almost all cables are ok. HDfury AVR-Key acts as a HDMI repeater device. So having a HDfury AVR-Key in
the path will amplify and recover the signal. You should not need any passive (or active) HDMI
