The CS-HDMABOD allows you to take an HDMI® source and de-embed the audio for use on either an optical audio connection or stereo RCA analog connection, all while still passing audio through on the HDMI® output, preserving the quality of sound. This de-embedder can also down mix multi-channel bitstream audio to stereo output to allow you to maintain 5.1 surround audio on the HDMI output. This next-generation product has been engineered with updated functionality to support HDMI® 2.0, HDCP 2 .2 (and earlier versions), and support 1080p, 3D, and 4K/60Hz 4:4:4 up to 18Gbps.
