Here's hoping some of the audio gurus in the community can come up with a best practice for the following situation.

Next week, I will be involved with two panel discussions in Kansas City.

- I will be on the dais as a panelist and have vMix running on a notebook computer in front of me.

- I have three microphones (wired and wireless) that can output either 3.5mm line or XLR mic levels.

- There will be one or two guests brought in via vMix call.

- There is a soundboard in the room, so I can plug our audio and/or vMix output audio into the room's amplifiers (I might also bring a portable speaker).

The potential issues:
1 - My vMix call guests need to be able to hear every microphone except their own (no problem, mix minus is a feature of vmix call)
2 - The folks in the room should not hear a delay imposed by vMix processing. Ideally, I could send a mic feed directly to the room's mixer and mute all but the vMix guest calls' microphones
3 - The folks in the room need to be able to hear any videos and guests from vMix.
4 - I need to record all the inputs.


Here is the equipment that I can bring with me
- xlr combo inputs accept either xlr or 1/4" male plugs
- all devices can supply phantom or plug-in power

a. Mackie 402-vlx3 conventional 4 channel mixer - 2 xlr-combo inputs, 2 1/4' inputs
b. Behringer UMC202HD - 2 channel usb audio interface. 2 xlr-combo inputs, a 1/4" headphone out, and two 1/4" (L+R) outputs.
b. Zoom H6 recorder - has 6 inputs (3.5 stereo and 4 xlr-combo), one 3.5mm line out, and can be used as a usb interface
c. iRig Pro - xlr-combo input, usb out
d. A USB audio adapter with 3.5mm mic in and 3.5mm mic out.
e. My computer has a 3.5mm trrs combo mic/speaker port

So... if you were me (and be glad you aren't) how would you configure the available equipment?

Thanks in advance!

Ovinus,

Thanks for your input... it will take a little thought one how to understand/digest your suggestion...

Other suggestions are most welcome.
