2. Click ON to mute it. The button turns red and shows MUTE.
3. Click again to turn it on. The button turns green again, showing ON.

## Muted until it goes to PGM

If you want to turn the sound on earlier, click the button: it turns on right away.


## Questions

### What is the difference between MUTE and disabled audio?

MUTE cuts the sound in the mixer, and you turn it back on with one click. Disabled audio (the speaker on the thumbnail) takes the input out of everything: PGM, Preview and headphones.
