Magewell USB Fusion HDMI & USB Video Capture Device - Manual (Page 66)

Getting to Know the Audio Mixer
Each scene has its independent audio mixer.
When a scene is selected, at the upper right corner of the App Main UI, tap
> Volume to open the audio mixer for the current scene.
The mixer will display the audio inputs and output involved in the current scene:
Output : Sets the output audio, namely, USB OUT audio, and audio for
monitoring, which is output through the headset port, WEB CAMERA 3 port,
HDMI OUT port.
Controlling Audio
USB Fusion allows you to adjust and monitor the input/output audio, both before and during your presentation.
The following describes how to use the App to adjust volume. You can also adjust volume and configure other audio-related settings on the Web UI. For details, see
Setting the Audio .
By default, the monitored audio does not include the global
microphone audio. If you need to monitor this audio, you need to
enable microphone monitoring on the Web UI.
■
By default, the WEB CAMERA 3 port does not output monitoring
audio. To enable output, you need to select an USB audio output
device on the Web UI.
■
When the HDMI OUT port loops the HDMI 1 or HDMI 2 audio, it
retains the original audio volume and remains unaffected by the
volume settings here.
