Digital/Analog Audio to HDMI Embedder - Replace HDMI audio with external Optical (TOSLINK/SPDIF) or Analog (3.5mm) input using a simple switch—choose Optical, Analog, or original HDMI pass-through without moving cables; note that audio is replaced (not mixed), and the correct input channel must be selected for proper transmission. 4K @ 60hz High Resolution - Delivers up to 18Gbps 4K@60Hz 4:4:4 video quality and also supports 1080p and 720p. Compatible with DVI-to-HDMI cables to merge DVI video with external audio into an HDMI output. Note: Only HDMI or DVI video inputs are supported—DP, VGA, and similar ports do not work with passive conversion cables. Full Audio Support - Supports pass-through of digital/analog audio including PCM, LPCM, Dolby, and DTS through HDMI. Optical input supports Dolby, DTS, and PCM, while the 3.5mm input supports 2-channel stereo PCM. Note: The device does not convert audio formats—audio output matches the original input (e.g., 3.5mm stereo in = stereo out via HDMI). DIP switch options: Line = 3.5mm input, Optical = optical input, Pass = original HDMI audio passthrough. Durable Metal Enclosure - Heavy-duty metal housing protects internal components and provides excellent heat dissipation for stable, long-term use. Compact design enables easy plug-and-play installation. Supports HDMI 2.0, 10-bit HDR, Dolby Vision, and is fully HDCP 2.2/1.4 compliant.
