Does the ATEM 1 M/E have audio pass through? If so, does it pass audio through from each source or only PGM audio? Specifically, if I route 4 different sources to the outputs (1 to PGM and 3 each to AUX) do they all get source audio or PGM audio?
Ideally I would like for audio and video from source 1 to be output through AUX 1, audio and video from source 2 to be output through AUX 2, etc. Is this possible?
Not possible that i've seen. All of the outputs are PGM audio, with the exception of the analog outs, that can now be switched to a 'Monitor' out from the audio panel of the switcher. There is no internal audio routing other than the mixer itself.
You may need a small HDMI or SDI router external from the ATEM to do what you're trying to do.
