Device Corrects 18G HDMI Video

Key Digital introduces the KD-FIX418A, a compact HDMI correction device for 18G HDMI video signals that includes audio de-embedding. The device resolves common HDMI integration obstacles related to HDCP, EDID, Hot Plug Detection, bandwidth, and audio de-embedding.

Units may be paired to compress and decompress 18Gbps video signals and extend via legacy 10.2Gbps cabling, or high-equalization may be applied on the HDMI input for repair of degraded incoming signals. Audio de-embedding on the KD-FIX418A enables external connectivity with audio distribution systems, amplifiers, and sound bars. The HDMI input is de-embedded through Analog L/R and Digital Coaxial Audio (PCM) audio outputs. 

The KD-FIX418A offers many different modes to fix 18G HDMI video signal problems. In down-convert mode the unit accepts an incoming 18G signal and down-converts into a 10G signal for integration into an existing matrix or video distribution system. The KD-FIX418A works with HDMI cabling for extension of 4K/UHD signals with HDR10 up to 50 ft / 15 m in and out using traditional copper HDMI cabling with the KD-PROGX series or up to 328 ft / 100 m in and out using Key Digital’s active optical cable KD-AOCH series. The KD-FIX418A offers 4K/UHD support for 4096x2160 or 3840x2160 24/25/30/60hz at 4:4:4(up to 18Gbps bandwidth).

Other features include Full Buffer System technology, which manages TMDS re-clocking and signal re-generation, HDCP authentication to source & display, and EDID handshaking control. HDCP authentication on the HDMI input gives the source the information and file it needs and is 2.2 compliant. Forced Hot Plug Detection enables the integrator or user to choose if the active signal voltage is forced to the connected input device. For more details, checkout the fixer page.
