How can I get ATEM microphone converter to treat each input as a separate MADI channel?
We're having 3 looped converters to feed 11 audio sources into an ATEM Television Studio HD8. But instead of showing up as separate channels every 2 sources appear as left/right on the same channel.
I searched all manuals but could not find a solution.

Any suggestions?

Every stereo pair including MADI may be split into two Mono channels in the ATEM. Go to Settings->Audio->Split MADI. I hope this helps.

Hi Gary,
I'm aware of that and did that already, but that's not the solution I'm looking for.
We're feeding 10 Mics and one line source into the ATEM Microphone converter.
Last week we used 6 individual Shure SLX and 3 individual Shure ULXD wireless system and all mics showed up on separate MADI channels, no need to split anything.
Now we replaced the SLX with ULXD4Q 4 channel receivers and all mics show up as stereo sources.
So instead of having 10 separate MADI channels for the mics, like before, we now have 5 channels with left/right audio.
There was no change in software on any of the ATEM devices, so I don't understand why this is happening.
Splitting is a workaround, but not the solution.

Splitting is the solution. MADI has no real concept of stereo pairs, it's just a bunch of mono channels sent over a wire. Stereo is context added by the source or destination, it's not transmitted over the wire.

In the BMD world, the Microphone converter just sends out four mono channels, regardless of what is plugged into it. The ATEM assumes all MADI / SDI / HDMI / XLR / whatever audio inputs are stereo pairs. There is no way for the microphone converter to tell the ATEM what you plugged in, even if it could somehow work it out itself. You need to take that step and tell the ATEM to split those feeds.

After you had this working last time, unless you saved (and restored for this job) a show file, or saved the startup state, the ATEM will have forgotten that you have split the channels. Equally, if you've loaded an earlier show file before the channels were split, that will have overwritten a config that may have been saved.
