The CS-HDMABO3 allows you to take an HDMI® source and de-embed the audio for use on either an optical audio Toslink connection or a 3.5mm stereo analog connection, all while still passing audio through on the HDMI® output, preserving the quality of sound. 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.
