How to use global microphones with USB Fusion?
Global microphones will work throughout a presentation, and do not switch in/out with any scene. USB Fusion provides three ports that allows global microphone
input, namely, the headset port, the line in port, and the WEB CAMERA port. All the global microphone inputs can work simultaneously.
Why is there no audio from the HDMI input source?
Check whether on the source computer connected to the HDMI 1 or HDMI 2 port, USB Fusion is selected as the audio output device. Only when USB Fusion is
selected will the computer output audio to USB Fusion.
The configuration varies depending on the OS system. For example, on Windows 10, choose > , then choose System > Sound , and select the name
containing USB Fusion (instead of USB Fusion USB-C ) from the Choose your output device drop-down list box.
Why is there only noise when I plug a headphone to the headset port?
Check whether your headphone uses the CTIA standard. The headset port uses the CTIA standard, so when an OMTP-compliant headphone connects to the port,
there will be some anomaly. In this case, you need to connect your headphone through an OMTP-to-CTIA converter.
Scene-specific audio includes the HDMI 1 audio, HDMI 2 audio, WEB CAMERA audio, and video file audio.
Audio outputs: USB OUT output audio, monitoring audio (output through the headset port, WEB CAMERA port, and HDMI OUT port). ■
When the headset port is connected with a headphone (with microphone), the microphone can work directly without any configuration. ■
When the line in port is connected with a microphone, the microphone can also work immediately. However, the volume of the microphone input may be low,
because the microphone signal is low compared with line in signal. In this case, you need to set line in gain to boost the microphone. For details, see Advanced
Settings .
■
When the WEB CAMERA port is connected with a device with microphone input, the microphone input is disabled by default and you need to manually enable it
on the Web UI. For configuration details, see Selecting a USB Audio Output Device .
