Blue Yeti and Snowball series microphones can connect to a Mevo Start via USB-C. Using the cable that came with your microphone, you will need a USB-C plug to USB-A port adapter to connect the microphone and Mevo Start camera.
In the Mevo Settings, navigate to Power and enable Power External Devices. You can learn more about the functions of the USB-C port here. After which, the microphone will appear in the Audio Mixer as “USB Device.” If this is your first time connecting, you may need to edit the input detailed here. Other driverless audio devices can also be connected with the same steps.
