MOUNT VERNON, NY, Oct. 04, 2018 (GLOBE NEWSWIRE) -- Key Digital, the award winning manufacturer of professional A/V and Control Systems introduces the KD-X444L extender kit ideal for installations requiring long range of 18Gbps video signal extension with HDCP2.2. 

KD-X444L will be a crucial tool enabling system integrators to extend UHD/4K video resolutions with HDR10 content over a single network wire.  This was previously not possible as such content could reach 18Gps bandwidth and extension technologies were limited to 10.2Gbps.  However, Key Digital’s award winning Engineers have surpassed the previous limitation and KD-X444L supports extension of 18Gbps signals up to 100m via a single CAT6A shielded twisted pair or CAT7 cable.  IR/RS-232 control signals are extended In addition to HDMI signals, for controlling remote equipment in professional A/V installations.

In applications that do not require UHD/4K resolution, yet have special needs for long distance, audio visual integrators may activate KD-X444L’s Long Range Mode feature.  With Long Range Mode enabled, 1080p resolutions may be extended up to 500t.  This makes KD-X444L a leading component in Digital Signage installations in large venues like airports, stadiums, and campuses.

High bandwidth signal support and long range extension are complimented by Key Digital’s proprietary Full Buffer Technology. 

“KD-X444L has a large assortment of trouble shooting tools ensuring that integrators install the product successfully the first time every time” said Jonathon Ferry, National Training Manager for Key Digital.  “Key Digital products have EDID control allowing integrators to choose up to 16 different EDID handshakes that can be provided to the connected source. The 4K handshakes also feature HDR, which means the installer no longer has to optimize the video settings in the playback devices.  With Forced Hot Plug Detection integrators can activate voltage to the connected source and to the connected display regardless of if signal is actually present which increases reliability for your system. We also have HDCP2.2 with all KD products ensuring that regardless of the source there are no issues integrating into professional video systems.

The KD-X444L features HDBaseT via Single CAT5e/6 UTP/STP extension with fully automatic adjustment of feedback, equalization, and amplification depending on cabling length. The extender set offers 4K support 4096x2160 or 3840x2160 24/25/30/60hz at 4:4:4 with signals up to 18Gbps bandwidth, and offers flexible power over HDBaseT with only one power connection needed with the Tx providing power to the Rx, or the Rx powering the Tx.
