For each audio source in the Audio Mixer, you can see that source’s levels, as well as a corresponding fader, speaker button, and ‘Audio’ button.
When switching sources, you may notice the different ‘Audio’ buttons turning yellow as you make the transitions.
This indicates that the audio source is heard in Program because its corresponding video input is in Program. It is not heard when the video input is not in Program.
If there is a particular audio source you want outputting to Program at all times, click the ‘Audio’ button; it will turn red.
This locks that input source’s audio into Program. Even if you continue switching video sources, you will still hear that audio source.
Click the ‘Audio’ button again to disable the locking. What you hear will revert to the default setting of following the video source into and out of Program.
If there is a particular source's audio that you do not want to hear at any point, click on the corresponding speaker button.
The button should go from white to black, and the levels will fade from green/yellow to gray. This indicates that the source is muted. You can turn off muting for any source by clicking its speaker button again.
Note: Muted sources can still be monitored through headphones as long as the headphone button is activated.
You can also link audio sources to each other. For example, if you have all audio coming in from CAM1, you may want to link other cameras to that source for seamless transitions.
Click on the name of the source at the top of the audio module. You will notice you have the option to link to any other input source.
Linking an input will cause the linked source to override the audio that had been coming in originally. The mixer will indicate which source’s audio is being heard.
In this example, CAM1 has been linked to CAM2, so viewers will hear CAM1's audio when either CAM1 or CAM2 are in Program. Notice in the image below how the levels are identical and both 'Audio' buttons are yellow (the red bar above the CAM2 label indicates that CAM2 is in Program).
You can link multiple inputs to one audio source for smooth transitions.
Most producers link ‘Record Out’ and ‘Stream Out’ together for consistent Program audio across all output sources. Those two sources cannot be linked to any other source.
To adjust the levels of any audio source, click and drag the corresponding fader for that source.
If audio levels are too high, the mixer's OVR meter for any over-modulating source will blink red.
You can also adjust the gain of each source by clicking and dragging the small gain meter above that source’s level meter.
