Magewell USB Fusion HDMI & USB Video Capture Device - Manual (Page 111)

Setting the Microphone Gain
A microphone can output audio at a relatively low volume. In this case, you can
enable microphone gain for the input to raise the volume. By default,
microphone gain is disabled.
In the VOLUME area, check Mic gain . USB Fusion will automatically gain the
microphone input to the maximum, namely, 40 dB. You can also adjust the gain
in Advanced Settings .
Enabling Microphone Monitoring
To avoid that a user can hear his or her own voice, USB Fusion disables
microphone monitoring by default. You can enable it if required.
In the VOLUME area, check Monitor mic . After enabled, the global
microphone audio will be output to the audio devices connected to the headset
port, WEB CAMERA port, and HDMI OUT port.
This gain currently applies only to the microphone connected through
the headset port, not to the one connected through the WEB CAMERA
port.
