Key Digital KD-FIX418A-2 HDMI Connectivity Fixer with Audio De-Embedding

KD-FIX418A-2 is a 4K 18G HDMI connectivity repair and audio de-embedding solution for HDMI extension coupling and signal correction in all AV systems applications. Analog and digital audio de-embedding on 3.5mm analog stereo & optical digital connectors enable integration of HDMI signals into distributed audio systems, audio DSPs, amplifiers, or sound bars. EDID handshake management, forced hot plug detection, and optional 4K to 1080p down-conversion tools help overcome common HDMI integration problems for ease of installation. KD-FIX418A-2 supports a variety of SD, HD, VESA and Ultra HD 4K video standards and has HDR header information included in many of the built-in 4K EDID handshakes for an optimized viewing experience.
