By default Premiere imports audio as Stereo.
But when I get files with say a boom mike on CH1 and a lav on CH2, I want to bring the audio as two Mono files, so that I can adjust levels -among other things- separately.
Go to: Premiere Pro CC/Preferences/Audio, and set: Default Audio Tracks / Stereo Media to Mono.
Easier than to change it after import.

The Adjustment Layers are great, but they modify all layers that are staked below. How to exclude some layers form the adjustment?
Easy: Select the Adjustment Layer, and "Create Clipping Mask" (Alt+Command+G) and the Adjustment Layer will now clip to the underlaying Layer or Group selectively, without altering other Groups or Layers. Neat.
You can do the same by clicking on the left bottom icon of the Adjustment Layer Properties Panel:
Another way is to hover over the space between the Adjustment Layer and the Layer or Group below it in the Layer Panel, hold "Option" and you will see the Create Clipping Mask small icon. Click on it.
Note that it is reversible: you will now see the "reverse / undo" Create Clipping Mask icon, click on it and the Adjustment Layer is back to "normal" - affecting every layer below - mode.
When round-tripping from FCPX to ProTools (or another audio editing/mixing app) and back, at the end of the mixing session, I bring my stereo DIAlog and MUSic stems into FCPX and sync them up.
Then I check proper sync against the working audio - still attached to the Video clips.
When all is good, it's time to mute the working audio. But how to do it without muting image as well?
Normally you'd mute a clip by pressing "V", this mutes both audio and image.
To mute audio only, select all your clips, and Right Click (CTRL Click) Expand Audio Components
Then select only the audio portion of the clip and hit "V". The audio component is selectively muted. Right Click (CTRL Click) Collapse Audio Components, and Master away!
