HDMI splitter features 4K to 1080p down-convert option

Aug. 11, 2021
Key Digital's KD-DA1x2DC is designed for sending 4K video content simultaneously to 4K and 1080p displays.

Key Digital, a developer and manufacturer of digital video processing and video signal distribution products, has introduced its KD-DA1x2DC, a 4K 18G HDMI splitter device with audio de-embed and 4K to 1080p down-convert capability.

The manufacturer says its KD-DA1x2DC - 4K 18G HDMI Distribution Amplifier with Audio De-Embed, 4K to 1080p Down-Convert unit "is engineered to offer quality, performance, and reliability at a cost-effective price point and has been designed for professional audio video installations in digital signage, surveillance monitoring applications, and more."

According to the manufacturer, providing added integration options in both new and retrofit instillations, the resolution down conversion option on the KD-DA1x2DC splitter enables a single HDMI video source to be displayed on two video displays regardless of 4K or 1080p resolution support. When enabled, the 4K to 1080p down-convert feature applies resolution conversion to each output individually based on the EDID from the connected display, therefore removing any guessing as to the display’s supported resolution on the part of the AV integrator, adds the manufacturer.

The KD-DA1x2DC features L/R analog and optical digital audio de-embed ports, enabling ease of integration into amplifiers, distributed audio systems, or sound bars. Audio de-embedding allows audio of the connected HDMI input to be output at the digital optical and analog 3.5mm stereo connectors. Ultra HD/4K video is supported at 4096 x 2160 or 3840 x 2160 24/25/30/60hz at 4:4:4 (signals up to 18Gbps bandwidth); the KD-DA1x2DC is also fully licensed and compatible with HDCP 2.2.

Further, the KD-DA1x2DC features HDR10 and Dolby Vision support to offer more life-like images through a greater range of luminance levels. Video resolutions up to 4096 x 2160p are supported and deep color is supported up to UHD/4K 30Hz 4:4:4/12 bits or 60Hz 4:4:4/8 bit. Also, Key Digital’s proprietary Full Buffer System within KD-DA1x2DC manages TMDS re-clocking / signal re-generation, HDCP authentication to source and display, and EDID control handshake functions.

The unit's EDID management feature includes an internal library containing 15 EDID handshakes including 4K with HDR in addition to native EDID data copied from KD-DA1x2DC output/display 1. EDID handshaking and Forced Hot Plug Detection professional tools help overcome common HDMI handshaking and integration problems for ease of installation in any environment. Digital audio formats supported include DTS-HD Master Audio, DTS:X, Dolby TrueHD, and Dolby Atmos.

The KD-DA1x2DC is priced at $178.00 (U.S.) and is available to ship starting in August 2021 from Key Digital and authorized resellers. Visit Key Digital's KD-DA1x2DC product page for more information.
