Using 3 or MOre Mics Through a Multichannel Interface?

[KenRyan]

If I had a Focusrite Scarlett 18i8 interface with 4 mic (XLR) inputs, will all 4 mics work in a Zoom meeting? If not, is there a way to use an app or something to combine all 4 inputs into a single channel so Zoom would recognize it?

Thanks!

Hi, @KenRyan 

I have never used that device so I don't know the details, but I checked the manual.
It looks like a mixer-amplifier, so it seems to synthesize the audio from four microphones and output it to the PC through a single USB port.
Generally, such a device is recognized by the PC as a USB microphone, so you can use it by selecting it as the Zoom's microphone.
However, you may need to follow the instructions in the manual for setting up the device and installing the special software.

Hi Ken,

I use the Focusrite Scarlett 18i8 with two mics on Zoom. I also use Ableton Live 10 Lite as a DAW for mixing the Scarlett output. You should have no problem getting Zoom to get its sound from the Scarlett as an audio source, regardless of how many mics you have plugged into it. The Scarlett takes care of all the mixing required.

Thanks Gerry! Yeah, it turned out that it worked just fine, despite all the warnings. :-).

Hi Ken - you can use the Focusrite Clarett 18i8 USB with multiple mics. There are instructions from Focusrite to make a loopback to do that. Check these two links:

The catch here is, I can get 3 mics working but the 4th mic is not heard by Zoom users - yet we can hear it in my studio. If you can get the 4th (or more mics) to work let us know. All the responses so far use only 2 mics which is very simple. The Focusrite video shows how to set up 3 mics but only implies you can set up more. So, any help would be appreciated. Thanks.

Hi. I have a related question. I am using a Blue Yeti mic as my main speaker mic. However, I need to have another USB mic to give to a live audience for questions. Does a Zoom meeting support two USB mics? If Yes how does it work? And does it matter which brand the mic is. I am thinking of getting the Behringer Ultralink ULM300USB.

If you can plugin both mics and select either one in Zoom that says that they are not conflicting at the digital level. If that is true then you can use OBS Studio to mix the 2 mics into a single output for zoom.

there seems no solution to this. I tried to get 2 usb mics into Zoom for almost a year. it doesn't work.

Actually, it is not impossible. Did you try learning to use OBS Studio?  I just plugged in 2 MPOW USB headset mics and linked them in OBS Studio and they mixed fine complete with separate volume controls and mute buttons.
