Check channel strip levels
All channel strips feature a segmented level meter that shows the playback or input monitoring level. The input monitoring level is shown when you arm an audio track in preparation for recording.
The colors of the level meter segments provide an at-a-glance overview of individual channel strip monitoring levels:
Amber and yellow: These signals are safe, and will not clip the channel strip output.
Red: These signals are considered “hot” levels, but the occasional peak is nothing to worry about unless the clipping indicator is continually or regularly lit.
For more information about signal clipping, see Peak level display and signal clipping.
Change the level meter scale
You can customize the level meter using two different scales, when Show Advanced Tools is selected in the Advanced preferences pane.
Choose Logic Pro > Preferences > Display.
Click Mixer, then choose a value from the Scale pop-up menu.
Exponential: Provides higher display resolution in the upper level meter range.
Sectional dB-linear: Provides the best possible display resolution across the entire level meter range.
