I run vMix with PTZOptic cameras and Magewell HDMI to NDI with no issues. My audio is noisy because I have to run 4 channel analog audio snake through 30' section of Cat6 with Radial XLR adapter going into my Presonus USB audio interface. The audio is coming from an analog PA system so no mixing is needed on the feed to our vMix system. I was thinking of getting one of the following audio Dante interfaces to capture the signal and route to vMix through Dante Virtual Sound Card. Has anyone had success with this? I am hoping I don't need any other receiver on my end with the vMix PC. I was looking at the RDL RU-MLB4P or the Tascam MM-4D.
My other option is using a Blackmagic CONVMCAUDS2 Audio to SDI Mini Converter and embed the four channels with one of my camera signals.
If no one has the answer, I may be the test subject.
Thanks,
Alan

i havent personally used Dante with the virtual soundcard but ive heard good reports from others.. if your audio from the PA is already mixed do you need it to be a 4 channel converter ? Audinate make their own adapters which are stereo XLR and might be cheaper option..
something else to keep in mind... if you do need four channels and you used SDI, im not sure you can seperate those four channels as independent mono inside vMix ? someone in another thread was asking about this, maybe its possible but if its not then you have more limited control.. you may not be able to do stuff like add VST plugins to each channel etc..

If you're thinking of the thread I think you are, the issue wasn't that they couldn't separate them out--it was that they had more channels than there were buses & they wanted a way to do it without tying up all of their audio buses.

30 feet isn't really a big ask. I've used XLR to CAT adapters on longer runs with no problems.
Are you using shielded CAT cable? Without the shield present, you're essentially running unbalanced audio since that shield carries pin 1 of all four XLR connectors.

Recommended solution. This solution is working great. https://youtu.be/lo8doTIS0F0?t=880

I installed a Tascam MM-4D with XLR in using Dante Virtual Soundcard (DVS). It seems that vMix can't record all 4 tracks separately or as two stereo wav pairs or as a 4 channel audio file. Unless I am missing something. I can mix as two stereo pairs into vMix to the master stereo. If I switch to 4 mono inputs from DVS into vMix, the audio slows in half and is long (my voice came through an octave lower in pitch with significant delay). I did reduce the Tascam bit depth to 16, keeping it at 48k.
I can use Tracks Live by Waves separately and record all 4 tracks individually.

my reference to that thread was to indicate how you dont have independant control without needing to separate the audio first, but i realize he was happy to use busses for that purpose and just didnt have enough of them..

I can use Tracks Live by Waves separately and record all 4 tracks individually. so as 2x stereo input in vMix it works ok but as 4x mono it lowers the pitch ? that might be a problem with how vMix handles channels/sample rates.. is there an option to change the 4x mono to 96khz in DVS ? that is not the right solution ultimately but maybe it will help get a better idea where the problem lies ? also is there anything in DVS which refers to "interleaved" or "non interleaved" if so try changing those settings and see if it works.. I would also try another program like Reaper or something and if (along with Tracks Live) it consistently works in other dedicated audio applications it suggests something around vMix audio handling..
