Key Digital Intros 4K/UHD 18G HDMI Distribution Solution

Key Digital just launched the KD-DA2x4G and KD-DA2x8G 18 Gbps HDMI distribution amplifiers with two HDMI inputs to four or eight (respectively) HDBaseT outputs for distribution to four or eight screens up to 100 meters / 328 feet away at 1080p resolution or 70 meters / 250 feet at 4K. All four / eight monitors are connected via included long-range HBaseT receive units. All receive units are powered by the KD-DA2x4G and KD-DA2x8G, relieving integrators from the troublesome task of plugging in power supplies behind each monitor.

The auto-sensing feature will automatically switch to a newly detected source or from a newly disconnected source via Hot Plug Detection voltage when enabled. Analog and digital audio de-embedding of the selected source enables the distributed video content to also be fed into connected audio systems. Control pass-through enables IR or RS232 signals from a professional control system to control connected monitors or be collected from an Rx unit and sent to the main equipment rack location for control of a selected source.

The KD-DA2x4G and KD-DA2x8G offer Ultra HD/4K resolution support at 4096×2160 or 3840×2160 24/25/30/60hz at 4:4:4 (signals up to 18 Gbps bandwidth), signal extension of 4K/UHD up to 76 m / 250 ft using CAT5e/CAT6/CAT6A/CAT7, and signal extension of 1080p up to 100 m / 328 ft at 18 Gbps bandwidth for the latest HDMI standards.

These distribution amplifiers offer resolution support of all SD, HD, VESA (VGA, SVGA, XGA, WXGA, SXGA, UXGA) up to 4096x2160p, HDCP 2.2 forward and backward compliancy up to HDCP 2.2, High Dynamic Range (HDR) format support of HDR10 and Dolby Vision and deep color support up to UHD/4K 60Hz 4:2:0/12 bits, 60Hz 4:2:2/12 bits. With support of HDR10 (High Dynamic Range) video users are able to experience more life-like images through a greater range of luminance levels. Key Digital’s HDR10 delivery is handled as part of their proprietary Full-Buffer Technology (FBT).

The KD-DA2x4G and KD-DA2x8G features EDID Control with a built-in internal library of 15 EDID handshakes in addition to the ability to copy the EDID data from the display connected to output/display one. The Full Buffer System manages TMDS re-clocking / signal re-generation, HDCP source and display authentication, Hot Plug Management and EDID Control handshake. Supported lossless compressed digital audio formats include Dolby TrueHD, Dolby Digital Plus, DTS-HD Master Audio and Dolby Atmos.
