KD-DA2x4G and KD-DA2x8G offer sizeable solutions for small & medium scale projects

Mount Vernon, NY – April 18, 2019 – The award winning manufacturer of professional A/V and control systems introduces the KD-DA2x4G and KD-DA2x8G high-performance 18 Gbps HDMI distribution amplifiers providing two HDMI inputs to four or eight respective HDBaseT outputs. KD-DA2x4G and KD-DA2x8G were designed for a superior distribution system without signal degradation, offering the best in quality, performance, and reliability while still remaining cost-effective.

What separates Key Digital’s latest distribution amplifiers from the competition is the front-end switching selection easily enabling different content to be distribution to all four / eight screens up to 100 m / 328 ft away at 1080p resolution or 70 m / 250 ft 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.

KD-DA2x4G and KD-DA2x8G includes a keen assortment of integration tools. 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 RS-232 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 4096x2160 or 3840x2160 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 impressive 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.

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 & 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.
