Function Integral 2 shares an HDMI AV signal from an input source (it has "INP0" and "INP1" inputs for two devices) and then directs through the multi-channel audio to an older 4K HDR incapable AVR or soundbar and the 4K HDR video to a 4K UHD F or a PProjector AV splitter mode. To share the AV signal and get the video signal from the output "OUT0" and from the audio signal from the "OUT1" output*, set the slider "SCALE" to "Auto Scaling" and the "EDID" to "Edid Automix Mode". * Select the appropriate input from the remote controls of the AV receiver and TV. HDMI switch mode. A short press of the "INP" button turns the active input source (сan is used when both devices are on). Turning off one of them could be more convenient. Hot plug detection. A short press of the "RST" button creates the "H ot P Lug D detection" (should be used if there is a problem with the identification of input and/or output devices).
