The Evolution by Vanco EVOSKILLZ is a first of its kind. This patent pending technology gives the ability to pass audio and video from an HDMI source and have the audio switched to a secondary audio source automatically via 3.5mm input. EVOSKILLZ comes equipped with an HDMI 2.0a input for audio and video, a 3.5mm stereo port to provide audio from a secondary source, and an HDMI 2.0a output which can pass the audio and video coming from the HDMI input, or embed the audio coming from the secondary audio source. Capable of passing 4K 60Hz with 4:4:4 chroma, with HDR10 and Dolby Vision compatibility, and can also pass through PCM, Dolby, and DTS audio. The micro-USB port can be used to power the unit or provide any needed future firmware updates. There are also 2 dials on the unit which allows the source sensitivity (gain) and audio time out to be manually adjusted. For embedding any analog audio over HDMI video, the EVOSKILLZ is a great and unique solution!
