How to run a USB Mic through an External Audio Mixer
Below is a diagram on how to run your wiring between the devices.
Plug your USB Mic into a USB Slot, run an appropriate lead from the Line Out/Headphone Out of your computer into a stereo input channel on your mixer. If your mixer has only mono channels, use channel one for your left, and channel 2 for your right. Next, run wires from the Main Output of the mixer to your Line in/Mic In on your computer, and the physical part is done.
Next, open up Voicemeeter (If you don’t have Voicemeeter you can download it free at VB-Audio.com) and select your USB Mic as the device for channel 1. Make sure “A” is selected/highlighted and “B” is not selected.
All that is left is to open up the app you want to use (eg – Skype, Vidblaster, or some other Web Cam program) and select Voicemeeter’s Virtual Device (Output “B” in Voicemeeter) as the input source audio device.
Voicemeeter can be downloaded FREE HERE at vb-audio.com. Don’t forget to make a donation – the programmer deserves a little something for a program this good!
