The Audio Mixer (AM) is refreshingly easy to use. We’ll assume, for this article, that we’re working with six channels of mono audio. The way the AM works is when you park your time bar over any part of your timeline, whatever audio tracks are there will become active in the AM. Now you can simply adjust the slider to the level you like, and you’re good to go. 

If you take a look at the image above, we have two audio channels in our timeline, and can make volume adjustments by adjusting the faders, pan adjustments by adjusting the knobs, or we can group tracks together by clicking on the tape icon at the top of each track. Bear in mind that you can’t rename any audio tracks from the AM. You have to do that from your timeline by right-clicking on a track, and selecting Rename Track.
